Washable coarse filters. Washing water filter - device and principle of operation. Advantages and disadvantages of direct flush strainers

The main reason for the breakdown plumbing equipment and household appliances in our homes is low quality tap water. Water flowing through many kilometers of main pipelines collects scale, sand, clay, hemp fibers, etc. on its way. It is good if the muddy, rusty stream of water does not clog your taps. In the best case, small stunted streams of water will still flow from the tap for some time, in the worst case, you will have to change all the plumbing at once, which adds up to a “penny”. Unfortunately, the situation with rusting pipelines will not change for the better soon, because, according to independent experts, more than half of all main pipes in Moscow need to be replaced, the average life of which is 40 years. In other cities, the situation is much more deplorable. And replacing all the pipes in an apartment or even a whole house will not work. Therefore, mechanical impurities deposited inside the pipelines lead to their premature corrosion. Owners of individual sources of water supply (wells, wells) also cannot do without mechanical cleaning water coming with particles of sand or clay and leading to the gradual disrepair of expensive plumbing. What to do in this situation? It turns out that plumbing equipment (showers, faucets, especially imported ones), washing machines and dishwashers will continue to break down due to poor quality water? But the way to deal with dirty water exists - before installing a sink, bathtub, toilet or other plumbing or household appliances on water pipes it is necessary to install mechanical filters. They will protect your equipment from dirt and save your nerves.

Mesh (washing) filters for mechanical water purification are designed to remove suspended particles, sand, silt and mud deposits from water. This allows you to significantly extend the life of the water supply system at home and plumbing equipment. Wash filters consist of a filter element ( metal mesh), enclosed in a flask made of durable material (plastic or brass). Mechanical impurities accumulate on the filter mesh and at the bottom of the bowl, and are easily removed when the flushing mode is turned on. During the flushing process, the flow of water captures mud deposits, which are removed either into a substituted container or into the sewer. Naturally, having bought the simplest and most inexpensive washing filter, you will have to take control over the degree of contamination of the filter element and wash and clean the mesh in a timely manner. The operation of disassembling and cleaning the filter is not very laborious, but dirty and requires free time. Therefore, the choice of the mechanical cartridge filter you need should be carried out from the tasks that need to be solved, and, of course, from your financial capabilities. To find out what degree of cleaning you need, look at technical documentation appliances connected to tap water. For example, for most plumbing and household equipment, a cleaning degree of 100 microns (microns) is suitable, but if you have expensive imported plumbing fixtures (jacuzzi, waterfall faucets, etc.), then it is better to take care of finer mechanical cleaning.

There are washing filters from various manufacturers on the market, such as Italian filters RBM, ITAP, VALTEC and etc.

We recommend washing filters for mechanical cleaning of the German manufacturer HONEYWELL(produced at the BRAUKMANN plant in Germany). HONEYWELL is a world leader in the development and implementation of the latest technologies in the field of space exploration, aircraft construction and the creation of new materials. Made with traditional German quality, the filters feature impact-resistant bowls, durable stainless steel filter meshes, and tight-fitting seals and connections. The degree of filter cleaning depends on the mesh size of the meshes used in Honeywell filters, which can be from 20 to 500 microns. The standard kit comes with a mesh with a mesh size of 100 microns. The smaller the cell, the better the degree of purification. Our company presents automatic washing filters and with manual washing. Dirt filters may be used before Honeywell fine wash filters, which extend the life of the filter components.

How Honeywell filters work with once-through flushing

The principle of operation of flush filters with direct flushing is similar to the operation of cartridge filters: during filtration, all mechanical impurities are retained by the filter element (mesh), and the water purified from mechanical impurities is supplied to the consumer. But there is also a significant difference from cartridge filters - the cartridge does not change, but is washed with untreated water (it is not necessary to disassemble the filter housing). At correct operation The washing filter and, taking into account the characteristics of the filtered water, the filter mesh is usually enough for 1-2 years. Direct flush filters have a drain hole at the bottom that is opened with a ball valve. A drain fitting is mounted in the ball valve, to which a flexible hose is connected or plastic pipe. When washing the filter, the ball valve of the drainage hole opens, and the water washes away the mechanical impurities deposited from the filter mesh. In order to prolong the service life of the filter mesh, it is recommended to periodically (after 5-6 washes) disassemble the filter and wash the mesh and flask more thoroughly with a brush, since water removes mechanical impurities from the surface of the mesh, and the particles stuck between the cells of the mesh remain intact.

How Honeywell Backflush Filters Work

Honeywell Braukmann has its own patented backwash technology that allows you to provide the consumer with a constant supply of filtered water, even while the strainer is being backflushed. The backwash filter mesh consists of a main lower section and an additional upper section. In filtration mode, the upper section is closed and water flows through the large lower section from outside to inside. When the ball valve is opened, the filter backwash mode is activated, in which the entire mesh element goes down. In this position, the water flow stops and it begins to pass through the small upper section, where, after cleaning, the water flow is divided into two: one for consumers, the other for backwashing. The backwash flow spins the turbine, and, passing through it with acceleration, cleans the lower section of the strainer from the inside to the outside. Thus, the main lower section under incoming pressure is completely cleaned over the entire surface of the mesh. After closing the ball valve, the flush filter automatically returns to filtration mode.

The built-in pressure relief valve operates on the principle of force equalization. The pressure force of the diaphragm in the filter is balanced by the pressure force of the adjusting spring. This means that the pressure at the outlet of the filter increases until the forces of the diaphragm and the adjusting spring acting in opposition are balanced. The inlet pressure does not affect the opening or closing of the valve. Therefore, a change in inlet pressure does not affect the outlet pressure. During filter backwash pure water continues to reach consumers.

Mesh washing can be carried out both manually and in automatic mode. In the manual version, there is an indicator to remember the date of the next flush. With automatic flushing, the drive can be started both in accordance with a predetermined time interval, and according to the pressure drop in the flushing filter or another external signal management.

What is the difference between co-current and backwash?

In the direct flushing process, water washes only the walls of the filter element and the filter bowl. This means that all the dirt collected in the flask will be washed away, but foreign bodies that have clogged into the cells of the grid cannot be removed. Over time, with direct flushing, the filter mesh will clog and the filter efficiency will drop. You will have to change the grid, which is associated with additional costs and downtime of the filter.

During the backwash process, water flows through the filter element in the opposite direction. Moreover, it does not just flow, but swirls with the help of a special impeller, and under pressure knocks out foreign particles stuck in the grid. Therefore, the backwash process greatly increases the life of the filter mesh.

The filter can be mounted on both metal and plastic pipes.;
The device is installed exclusively on a horizontal section of the water pipe with the bowl down(this allows for maximum filtration efficiency);
Mounted downstream of the water meter and shut-off valves in accordance with DIN 1988 part 2(this makes it possible to maintain the filter without dismantling it from the pipeline);
Provide Free access to the backwash filter for contamination control, pressure gauge readings and maintenance ;
It is recommended to leave a straight stabilizing section of the water pipeline after the combined filter with a length of at least five times the nominal connection size.

Purification of water entering the apartment from various mechanical impurities is very important. Not only the final quality of the liquid used for drinking depends on it, but also the service life of all kinds of household appliances. Ordinary ones, as a rule, require periodic replacement of cartridges after the filter element has exhausted its resource. A washing filter for mechanical water purification is much more convenient, as it allows you to restore, at least partially, the characteristics of the cleaning element in a short time. In some cases, it does not even need to be removed.

Principle of operation

Advantages

The advantages of water filters without replaceable cartridges are obvious:

Significant monetary savings, since there is no need to purchase replacement elements that have limited time services.
Maintenance of such units is much more convenient and must be carried out after a longer period of time.
The cleaning process does not require stopping the water supply in the apartment.

The disadvantages of self-flushing devices include a rather high cost and demands on the parameters of water supply to the room.

Kinds

According to the size of the trapped impurities, they distinguish:

Fine filter capable of capturing pieces of rust and sand with a size of 20-50 microns.
Coarse cleaning devices that allow filtering elements with a size of 100-500 microns.

According to the cleaning method, self-cleaning filters are:

Washed by hand. This does not mean that you have to remove the filter element from the system. The procedure can be carried out even without stopping the water supply. But manufacturers still recommend removing and washing the mesh separately. Although this is not a very convenient procedure, it will have to be performed much less frequently than replacing replaceable cartridges. In addition, it does not require any financial costs.
Semi-automatic. For such models, you will only have to manually give a command for cleaning, the system will do all the work itself. AT different models Different manufacturers self-cleaning filters are cleaned in different ways, much depends on the type of cleaning element and the design of the unit.
Automatic. The process is triggered by indications various sensors. Another option - cleaning is performed according to a pre-set timer.

The last two varieties are rarely seen in a separate apartment. Such self-flushing units are more often used on high-pressure main water pipes, which serve to supply water to swimming pools or entire houses.

Get better self-cleaning filters well-known manufacturers. You can rely on the reviews of friends and acquaintances. This will save you from unnecessary surprises, save money and time.

With water from a tap, in addition to the liquid itself, foreign particles, such as rust, grains of sand, and hemp fibers, can also enter pipes and household appliances. They settle in pipes and surfaces of household appliances in contact with water, which invariably leads to blockages and breakdowns. Suspended particles larger than 100 microns on the mixers leave micro-scratches. Constant contact with the surface leads to the fact that it gradually becomes thinner and begins to leak. AT this case way out of this situation can be mesh filters for direct flush water.

The principle of operation of the washing filter for water

It is quite possible to solve the problem with a “leaking” tap at the “prevention” stage. In this case, a flush water filter is installed, which is suitable for city apartments. There are also main filters designed for high performance. The main task of any filter of this type– protection of household appliances and plumbing from large impurities.

The principle of operation of this filter is quite simple: particles passing through the filter with water are retained on the steel mesh. Gradually, pollution accumulates on the surface of the mesh. To keep the filter in working condition, it must be washed.

Rinsing is carried out using a direct stream of water, which flushes contaminants into the drain. The process is started with a simple turn of the valve knob. It should be noted that during this process no water is supplied to the system. But this minus is smoothed out by the fact that the washing procedure itself takes no more than three minutes. The liquid after washing is drained either into a separate container or into the sewer. The latter requires an additional inset.

This method of cleaning does not give 100%, and therefore 1-2 times a year it is necessary to clean it yourself with a toothbrush. If this method does not help to clean the element of dirt, then you need to buy a new mesh and install it in place of the old one. As a rule, the cost of this part does not exceed 500 rubles. But if the cleaning is done in a timely manner, then the mesh is replaced no more than once every three years.

Advantages and disadvantages of direct flush strainers

As previously noted, during flushing, water is not supplied to the system. But the process is optimized so that cleaning does not take much time. Also similar systems (an example would be honeywell direct flush water strainers) in individual models equipped with a valve that lowers the pressure, which will protect the system from possible water hammer. It also allows you to set the same pressure level for both hot and cold water. But this factor is possible only if filters with a gearbox are installed on the cold and hot lines. This advantage will also greatly simplify the process of adjusting the water temperature with the help of a mixer.

But if we talk about the disadvantages, then often such a filter is simply not enough for high-quality water purification, since not only suspended particles, but also dissolved elements, gases, and microorganisms can be present in the liquid. Therefore, the issue of high-quality water purification is approached comprehensively. This is especially true for apartments. Water, before reaching your faucet, passes through old rusty pipes, in which harmful elements and microorganisms accumulate for years. Therefore, they are used different systems water treatment and water treatment. They provide the highest quality water purification, depending on the indicators of the chemical analysis of the water sample and the method of use.

The dimensions of such filters are small, and therefore, in a limited space, they are quite easy to embed with the water supply system, without taking up extra space. The thicket of the filter for cold water is made of impact-resistant transparent material, and for hot water it is made of brass. The maintenance process does not require dismantling the filter from the pipeline, thus ensuring easy replacement of elements.

It should be noted that such filters can not only remove large impurities, but also absorb iron and manganese, softening the water.

For all their merits, such filters are not very expensive, remaining accessible to all segments of the population.

Combined Methods

Combined nodes

The flush water filter is designed for more or less large contaminants. Smaller, dissolved elements, microorganisms, it does not delay. Therefore, quite often with mechanical cleaning, they use:

Reagent Methods
Reagent-free methods

The filtration process itself already belongs to the reagentless methods. But an additionally equipped water treatment system with special systems makes it possible to obtain a clean and useful water. It is also useful because the purification process not only does not make the water distilled, but in some models it also enriches it with additional trace elements, bringing the liquid to an ideal state.

An example of the use of self-cleaning water filters in integrated approach can become a system reverse osmosis, which is considered one of the best in the field of water treatment.

Heavy metal salts, hardness, nitrates, bacteria and much more are removed by such systems not only quickly, but also qualitatively. According to studies, the degree of such purification can reach 99%.

From mechanical impurities - one of the most common things that can be encountered when consuming water, even from a water supply system (which has already passed the stage of water treatment, ideally) There are many options for how to deal with such pollution.

1.1 Types of filters for cleaning from mechanical impurities

Another model of flush type filter, inlet diameter ½ inch

The main types are as follows:

Coarse cleaning methods are used (particles ranging in size from 20 to 100 microns are removed);
Fine purification methods are used (they purify water from particles of 1-5 microns in size).

Separately, the so-called “mud filters” (including industrial ones) are considered, the task of which is to keep dirt from entering the system (here we are not talking about fine cleaning, they can be used when water is supplied from a well).

In this case, the filters are mounted mainly at the outlet of the well. This is done so that the water is purified on the approaches from the well, and already enters the system in a usable form.

In the case of using a well as a source of water, coarse cleaning will be indispensable in the water treatment system (as well as fine cleaning products).

Filter cleaning methods are divided into:

Flushing (usually - main);
Non-flushing (usually a cartridge is used).

A feature of filters in which a cartridge is used (including fine cleaning) is precisely the inability to rinse the filter cartridge; after the end of its service life, it must be replaced.

At the same time, cartridges for filtering hot and cold water are not interchangeable, since the temperature is higher than that for which the housing is designed, deforms it or the cartridge.

In addition, it should be borne in mind that the life of the cartridge may vary depending on the composition of the water, and if it is necessary to replace it, you will have to shut off the water supply.

The flushing filter (including the main one) involves certain methods of cleaning the filter element.

The same blocks for hot water are usually opaque and metallic. The transparent housing of the filter for cold water sometimes allows you to "assess its condition by eye".

2 Which wash filter for mechanical cleaning should be chosen?

If you buy a main hot or cold water filter using coarse or fine cleaning methods, for domestic use, a model with the possibility of backwashing will be more convenient (also suitable for supplying water from a well).

Despite the fact that the main filter can be washed in one way or another without shutting down the system, it is recommended to flush the mesh separately (that is, still turn off the system for a while), but this is done much less frequently than you need to change the cartridge.

If we compare the types of filters (regardless of whether they are designed for hot or cold water and what methods they use) - mesh or disk - it is often mentioned that disk type filter under similar conditions, greater productivity due to the larger filtration area.

But, only the difference in the size of the filtration unit can provide a big gain, and with similar sizes, both the mesh and disc filters show the same indicators for the water passed through them (including in the case of fine cleaning).

At the same time, a coarse or fine disc filter may be more demanding on the pressure of incoming water than a mesh one, and also be more expensive.

Before buying, you should decide on the parameters of the system on which the filter will be installed using coarse cleaning methods, and it is planned to use it for hot or cold water.

If the main filter is installed separately, it is necessary to check that the pipe connections and the diameter of the pipe and filter connections are compatible (or take care of their fitting).

If a cartridge type filter is installed in a block filtration system, care must also be taken to ensure that all blocks are compatible.

Accordingly, the choice is based on the following parameters:

Is the filter standalone or will it be installed in a multi-stage system. Sometimes the main filter is installed on the pipeline in a separate apartment, for example;
What type of filter will be installed and whether it is compatible with the piping system (filter working methods);
Depending on the type chosen, the manufacturer and cost are determined.

Directly from the products of various manufacturers, we can mention filters (coarse and fine cleaning) Honeywell or Atlas, and from the manufacturers of the CIS countries - the Russian Geyser.

The products of the Danish company Honeywell are distinguished by reliability and build quality. Filters of the described type from Honeywell are usually equipped with a backwash system. And also from Honeywell filters you can expect and additional equipment(with a built-in pressure gauge, for example).

Honeywell filters are also highly resistant to wear and pressure surges because the filter housing is made of solid brass (a feature of this Honeywell product). The downside here can only be the cost, that is, less Honeywell filters are less available.

Water purification filters from the company, according to the manufacturer, compete with European counterparts and are used both in Russia and in European countries.

Under the brand name Geyser, both separate types of filters for mechanical cleaning and entire systems for various purposes are produced ( complex cleaning water for cottages and country houses, purification technology for enterprises).

As a result, several specialized Geyser solutions compete with more universal counterparts. The Geyser company produces both mesh filters and filters where a cartridge is used. A comparative advantage of the Geyser is also the price (compared to the previous manufacturer).

Thus, Geyser products will be more budget option. Therefore, when choosing between Geyser and Honeywell, we will prefer Geyser in terms of cost, and Honeywell in terms of quality.

2.1 Demonstration of the operation of the wash filter (video)

Wherever you take water from, it will contain various impurities: sand, small stones, as well as waste that is generated as a result of our life. If the water contains debris particles, the pipes will begin to clog and deteriorate, which means that the plumbing will need to be repaired. To prevent such problems, water must be purified using special washing filters.

From this article you will learn:

How to install such a filter

What needs to be done to make the wash filter last longer

What is a water filter for?

Main flush filters are necessary to remove various clogging particles that are suitable for all water temperatures. The cleaning result directly depends on the size of the cells in the wash filter.

How the mesh washing filter works, we think, is clear to everyone. It consists of:

Cases with openings for the inflow and outflow of water.
A filter mesh in the form of a cylinder.

The main disadvantage of using such washing filters is the clogging of the mesh itself. Pollutant particles settle on its surface, which becomes slagged over time, and, as a result, water does not pass well. Cleaning requires rinsing with water different directions, and then the garbage accumulated after such processing is removed through a hole with a tap.

There are forward and backwash filters. In the first, the water that removes contaminants from the grid moves in one direction - from top to bottom. Cleaning occurs due to the strong pressure of water, which washes away all the slags into the container. Stops this process after turning the valve lever. The second type of washing filters for cleaning involves the movement of water while removing contaminants from the bottom up.

Wash filters are simple and complex. The cleaning of those that are simpler is started by the user. More complex equipment, as a rule, is equipped with special devices and can be automated. Devices can show time and pressure, as well as independently switch to flushing mode.

We want to note the backwash filter. Its design allows you to clean the mesh without stopping the process of water purification. Flushing should always be of the highest quality, therefore, manufacturers of cleaning systems also offer devices for:

suction of contaminants;

automatic washing;

manual washing.

Filters can be cleaned for a certain time (by a timer) or according to the indications of a special device that measures pressure. Flushing water filters with a pressure gauge are able to automatically switch to backwash mode in case of significant clogging.

The washing filter is applied to cold and hot water.

Nets for washing filters are made from:

steel sheet;

woven threads;

polymers.

The durability of mechanical washing filters is influenced by the quality of the mesh itself and the reliability of the entire structure for water treatment. Reliability depends on the following indicators:

cleaning quality;

slip coefficient.

Particles can move irregular shape, which are sometimes arranged in such a way that the grid does not hold them. The flush water filter will not be reliable enough if the angle between the mesh and the flow is straight. With an increase in the speed of water movement, the resistance of the washing filter mesh increases. This indicator affects the quality of the device used for cleaning.

As the water velocity increases, the likelihood of a breakthrough increases, and therefore, fewer debris particles fall on the flush filter mesh. To reduce the speed, you can increase the grid area, but this is difficult.

You can use laser punching, then the washing filter will purify the water more efficiently. The mesh must prevent the formation of rust, since the filter is necessary to purify water of various temperatures. If there are substances in the water that contribute to the dissolution of metals, the likelihood of corrosion on the grid increases.

Stainless steel meshes are often used for both industrial and domestic flush filters. The polymer mesh is less strong, but debris particles will not stick to it, which means that it is easier to wash it, and the device itself will work more efficiently.

How to install a water filter

Firms producing washing filters for water, in the documents attached to these devices, describe all the stages of their installation.

The installation of a flush water filter requires compliance with safety regulations when carrying out work related to the installation of main flush water purifiers, as well as hygiene and technical requirements to the filtration system. The flushing filter must be installed in a heated room to avoid water freezing. The device is installed with the flask down, the pipeline can be horizontal or vertical. It is necessary to comply with the conditions of installation and construction. In addition, it is very important to pay attention to the direction of the water flow (this information can be seen on the filter cover). When installing a device with automatic flushing, it must be connected to the mains.

How to clean the water filter

The main flushing flow filter for water has an additional hole (at the bottom of the flask). There is a rotary valve on the lower outlet, which is closed during normal operation of the appliance. When dirt accumulates in the flask, impeding the movement of water, the valve must be turned. This increases the flow of water, and the blockage goes into the drain from the grid and from the bottom of the flask. After the flushing filter has been cleaned, the valve must be turned again and left in this position until a new flush is required.

Sometimes an empty bucket is placed under the hole, but more often they do it differently. Now they produce such washing filters, to the hole of which a hose can be connected (for this, the design implies the presence of a fitting). From the hose, water goes straight into the sewer. This cleaning scheme makes this process as simple as possible, you just need to turn the valve a couple of times, and the water itself will wash everything.

Important! Often, one or two pressure gauges are included in the design of washing water filters. The dial of this device, located at the top of the filter, is not a decorative element. When water passes through the filter, its head and pressure decrease somewhat. With an increase in the pollution of the grid, the water pressure at the outlet decreases. The degree of contamination can be determined by the difference in pressure at the inlet and outlet. If this value is more than 0.5 atm, the filter must be washed. This is very important when the flask is opaque and otherwise it is unlikely to be able to determine whether cleaning is needed. However, such a check can also be done empirically: observe the pressure of water in the tap. But this method does not always give an adequate assessment, since the water pressure can change due to the fault of the local water utility.

Flushing flow-through main water filters can be self-cleaning, but the mesh may deteriorate during operation. Small particles of debris will accumulate in the appliance, which over time will lead to the formation of a large number clogged cells, throughput decrease. In this case, simply turning the valve will not solve the problem.

The most extreme measure in this case is the replacement of the washing filter. Some manufacturers sell fixtures with spare grids. In addition, the grid can be cleaned on its own, but its original characteristics will never return to it. There are filters with backwash, they are not afraid of clogging the cells. In the process of direct flushing, water moves down along the grid, and during reverse washing, it flows from the inside of the grid to the outside. Water has such a pressure that the slag is washed out of the cells, and then it is removed from the flask through the drain fitting.

The backwash mechanism, which cleans the filter when water moves from the inside of the mesh to the outside, can be implemented in different ways.

Wash filters for mechanical cleaning are different. There are universal models that can be used to clean hot and cold water, their body is made of brass or bronze. Also, wash filters can be designed only for hot or cold water. In devices for low temperatures the flask is transparent, made of plastic, which allows you to visually determine whether cleaning is required on this moment. The plastic from which the filter bowls are made is durable and can withstand pressure up to 16 atm. Models with brass bowls are suitable for both hot and cold water.

Important! The cleaning of the washing filter must be approached carefully, it is necessary to control this process: open the valve in time and drain the water with the collected dirt. It is possible to make this process carried out completely independently.

And it's real! In fact, you can choose a model of a water flush filter that has an automatic flush drive built into it (the filter must be connected to sewer outlet). You just need to set the required interval, and the system will switch to cleaning mode on its own. Power is supplied from the mains or from batteries.

Optionally, a differential pressure switch can be connected. It will measure the difference in water pressure between the inlet and outlet of the flush filter and automatically turn on the flush actuator when this parameter exceeds a user-defined value.

What you need to know in order for the washing filter of mechanical water purification to last a long time

Always make sure that the temperature of the treated water matches the operating conditions. The flush filter should not be installed near heating systems(over 35–40 °C).

It is very important to monitor the working pressure. If the norm is exceeded, the entire system can be damaged, and a lot of financial costs will be required to repair it.

The filter should be cleaned at least once every six months. You can determine the need for it both by the difference in water pressure, and visually, simply by looking at whether the flask is transparent.

To clean the wash filter, you must use the amount of water specified by the manufacturer, passed per unit of time in a safe mode. Do not exceed this value, otherwise there is a high probability of equipment failure.

Washing water filters can be purchased in various configurations, while prices will also differ. In addition, prices may not be comparable for the same product. different manufacturers. Therefore, if you want to purchase the most economical option, choose high-quality equipment.

There are many companies on the Russian market that are developing water treatment systems. It is quite difficult to choose one or another type of water filter on your own, without the help of a professional. And even more so, you should not try to mount a water treatment system yourself, even if you have read several articles on the Internet and it seems to you that you have figured everything out.

It is safer to contact a filter installation company that provides a full range of services: specialist advice, analysis of water from a well or well, selection of suitable equipment, delivery and connection of the system. In addition, it is important that the company provides and service maintenance filters.

This is the Biokit company, which offers online wide selection reverse osmosis systems, water filters and other equipment capable of returning tap water to its natural characteristics.
