Reverse osmosis is the most common deep cleaning technology today tap water... It is based on the use of a partially permeable membrane, which is able to purify water from salts and other unwanted impurities.
The principle of water purification method reverse osmosis quite simple: under pressure, water molecules pass through a "sieve" of a semi-permeable membrane, then through finishing carbon filters, where foreign odors and tastes are finally removed from the water, its acid-base balance is normalized. The output is ultrafiltered water, completely suitable for drinking and cooking.
All larger particles of the source water are retained and are sent through the reverse osmosis system to the drainage (sewer).
Structurally, this filtration system consists of several cartridges with carbon filters and a membrane, as well as a reservoir for purified water. 
Reverse osmosis systems, like any other filter elements, can clog over time, some of its elements may not work correctly, which reduces the filter's performance.
If the filter emits extraneous sounds, vibrates, works slowly, does not drain water, or, conversely, sends a large amount of water to the drain, then the following parameters should be checked:
If serious problems arise (diaphragm damage, tank leakage, etc.), it is required reverse osmosis repair... However, very often malfunctions are local in nature and you can fix them yourself.
Here is a list of the most common problems and how to fix them:

The reverse osmosis membrane may fail earlier than the declared resource for the following reasons:
To check the performance of the membrane, you should measure the amount of water sent to the drain and the amount of purified water. It is considered normal Reverse osmosis efficiency 5-15%, i.e. 85-95% of the water goes to drainage.
The easiest express way to reliably check the performance of the membrane is to purchase a TDS meter. This small salt meter, which costs about 1000 rubles, allows you to find out the content of impurities in the water.
After osmosis, the TDS meter should show no more than 15 units. If the indicator is higher, then the membrane is not working efficiently and needs to be replaced.
Don't even open
There will be no photo of the parcel, some pimples, tracks and other crap. Mail works! All parcels to me in Moscow reach a maximum of a month and a half.
.And a few more points from the experience of operating such systems:
1) Be sure to thoroughly check the entire system once a year for microcracks, the integrity of the gaskets, etc.
2) After 3-4 years, I recommend replacing all three lower plastic flasks (I had two cases when the flask was pulled out along with the thread, the upper part burst). The solenoid valve, if installed in front of the entrance to the system, will save your apartment from a flood!
3) I recommend installing the solenoid valve at the inlet of the first dirt filter (in most systems, the crab is set to cut-off between the first and second filters) See item 2!
4) UPD! A very common mistake: "inflate" the storage tank! Many people believe that pumping will increase the pressure in the filter. Yes, they will, but not in the filter, but in the tank itself. As a result, less water will be filtered into the tank.
The storage tank has a built-in rubber bulb that separates the air (lower part) and clean water (upper part). By increasing the pressure at the bottom, you reduce the usable space at the top. There is a label on the storage tank indicating the working pressure (100psi = 6.9 atm). This is what you need to leave!
5) UPD! Another common mistake is replacing the "crab" in the hopes that it will raise the pressure. Any new "crab" (this is how it works) with a gradual filling of the storage tank GRADUALLY reduces the inlet pressure to the filter. The option I proposed solves this problem as well!
You can check the filter like this:
Remove the "crab" from the system (accordingly, you need to restore all connections, you will need spare tubes)
Close the storage tank
Turn on the water. See how water flows out of the faucet at the sink. There should be a continuous trickle with a thickness of 1-2 mm.
At the same time, you can fill some container with this clean water, and put the tube that goes into the sewer into another container. So you can estimate the approximate water consumption.
If the trickle is very thin or dripping, then the OO membrane may be clogged.
And it is possible and really the pressure in the water supply system is very low. But here you can't cure it with any settings, just set it. But such an upgrade is quite overhead (about 4000 rubles: the pump itself + relay high pressure+ relay low pressure+ fittings and tube).
Alternatively, abandon osmosis and install an ultrafiltration membrane. She needs much less pressure. Filters slightly worse. It is installed in the same housing as the OO membrane. And the storage tank and all the OO piping (check valve, crab, flow restrictor) are removed.
I did not plan to do a review, I wrote in a hurry
If you have any questions, I am glad to suggest.
I plan to buy +52 Add to favourites I liked the review +38 +78The reverse osmosis system constantly drains water down the drain.
Check if this is really the case. Shut off the water supply to the tank. In order to close the water tank, climb under the sink and close the lever on the tap (blue) at a right angle (90 degrees) to the water flow (hose). If after 30 min. the water is still discharged into the drain, it's either in pressure, or in the reverse osmosis membrane, or in the valve after the reverse osmosis membrane, or in a four-way valve.
Close the tank and open the tap on the sink. Reverse osmosis should purify water bypassing the tank. If the flow of purified water is small, about the size of a trickle as thick as a pen shaft, the membrane works normally.
Check the outlet water pressure just before the reverse osmosis membrane. If the pressure is more than 6 atm. wait until the water supply pressure of your home has equalized, or install a pressure reducer. The cost of a reducer that equalizes pressure from 250 UAH. up to UAH 350 depending on the country of manufacture. For the operation of the reverse osmosis system, a pressure of 3 - 4 atm is required. If the water pressure is less than 3 atm, install a pump, the cost of a pump set is from 1500 to 2000 UAH.
Check the four-way valve, it should shut off the water supply to the system after a few minutes, with the tap on the storage tank closed. If it does not overlap, replace the four-way valve (cost 69 UAH).
If the check valve is faulty, the tank with purified water is full, but the discharge of water into the drainage does not stop. Replace the non-return valve (cost 45 UAH).
Bad taste of water after the reverse osmosis system. If the water after cleaning with a reverse osmosis filter has a taste, then the matter is most likely in stagnation of water. Complaints about the bad taste of water after additional upper cartridges of a mineralizer or a bioceramic cartridge are not related to the fact that these filters add something to the water, but to improper operation of the water filter. The water treatment cartridges contain up to three glasses of water. This water, like the water stored in the tank, must not stagnate. To eliminate foreign taste and odor, you must either use a mineralizer (bioceramic cartridge) every day, or drain the first few glasses of water.
If all the water after the filter has unusual smell or taste(from both tap wings, or in cases where the mineralizer is not installed), the water stagnates not in the filter cartridges, but in the water tank. Here the most common cause of the problem is the missed period for replacing the post-coal cartridge (once a year), or incomplete use of the tank resource (accumulator). If you cannot fully use its volume during the operation of the filter (tanks are of a capacity of 15 liters - 12 liters, 11 liters - 8 liters and 8 liters - 6 liters), it becomes necessary to artificially renew the water in the tank once a month. You can turn off the tap in front of the filter and gradually use the excess purified water, you can collect a large container or simply drain all the water from the tank down the drain. If the filter will be used by 1-2 people, the smallest tank (8L) is recommended during installation.
Low head from the tap in the reverse osmosis system... The low pressure from the tap of the water filter is most likely due to improper operation of the tank. The rate of water purification by a reverse osmosis filter is small. It can be thought of as a trickle as thick as the shaft of a pen. In order to immediately be able to pick up a large vessel or at least a glass, a storage tank (hydraulic accumulator) is provided in reverse osmosis systems. If water does not flow into the tank, the filter is idle. When you open the tap, water sprinkles and immediately flows in a trickle. If nothing interferes with the flow of water into the tank (the pipes are not pinched and the tap on the tank is open), then the problem is in the improper operation of the tank.
The tank is empty and no water flows into it... Open the tap on the tank by turning the lever on the tap (blue) parallel to the water flow (hose). Check the inlet water pressure just before the reverse osmosis membrane. If the pressure is less than 3 atm. wait until the water supply pressure of your home is equalized, or install a pump. The cost of a pump set that increases pressure for a water purification filter is from UAH 1,500. up to UAH 2000 depending on the country of manufacture.
The tank is full and no water comes out. Open the tap on the tank by turning the lever on the tap (blue) parallel to the water flow (hose). If the tap on the tank is open and there is no mechanical blockage of the flow of water, which should be drawn in and out of the tank, it is a matter of the internal pressure of the water tank. If the tank was initially working and it was not exposed to any external influence, it is necessary to increase the internal pressure of the water tank. Unscrew the cap on the side of the tank. Under the cap there is a conventional nipple for pumping air, the same as on the tires of a car or bicycle. Pump up with a pump to a level of 0.5 - 1.0 atm. If the water tank still does not draw or dispense water, replace the tank. The cost of an iron water tank of 8 liters is 570 UAH.
Reverse osmosis system slowly picking up water... Open the tap on the sink. If the flow of water is small, about the thickness of a pen rod, reverse osmosis works fine. Check the degree of contamination of the pre-filter water cartridges by appearance if you have transparent flasks, or unscrew the flasks and check the degree of contamination directly. If, due to the service life, or the deterioration of the quality of the water supplied to the reverse osmosis, the pre-treatment cartridges are out of order, replace them. Check the inlet water pressure just before the reverse osmosis membrane. If the pressure is less than 3 atm., Wait until the water supply pressure of your house is equalized, or install a pump. The cost of a pump that increases pressure is 1500-2000 UAH. Press the ring onto the fitting in front of the post-coal cartridge and pull the hose out. If the flow of purified water is as thick as the handle rod, then there is a mechanical blockage on the way from the reverse osmosis membrane to the tap. Check all connections of the water filter downstream of the membrane step by step. If the flow of purified water occurs drop by drop, then the reverse osmosis membrane, due to the service life, or the deterioration of the quality of the water entering it, is out of order. The cost of a reverse osmosis membrane is from UAH 350. up to UAH 700 depending on the speed of cleaning the reverse osmosis membrane.
The correct operation of a reverse osmosis system as well as its performance depends on several variables:
So, for example, with a deterioration in the quality of the incoming water (high total mineralization of more than 500 ppm) and a decrease in its temperature (in winter water in the water supply system is less than 15 ° C) for the effective operation of the reverse osmosis system, an inlet pressure of at least 4 atm is required. At lower pressures, a pressure boosting pump kit must be installed.
Total mineralization 500 ppm, temperature 15 ° C, pressure 3 atm - THE SYSTEM WORKS EFFICIENTLY.
Total mineralization> 500 ppm, temperature<15 °C, давление 3 атм - THE SYSTEM DOES NOT OPERATE EFFICIENTLY.
Total mineralization> 500 ppm, temperature<15 °C, давление >4 atm - THE SYSTEM WORKS EFFICIENTLY.
Osmosis is an integral part of the life of living organisms and plants. Which ensures the metabolism at the cellular level. In this article, we will consider the reverse osmosis system: the principle of operation, its application, as well as the advantages and disadvantages.
There are two types of osmosis:
1) Direct osmosis system
2) Reverse osmosis system
Direct osmosis is a one-way diffusion of solvent molecules using a special membrane towards its lowest concentration. If the membrane were absent, then there would be just concentration equalization in the vessel. The transfer is caused by osmotic pressure. Pressure, as a rule, depends on the type of solvent, composition and concentration of dissolved impurities.
Reverse osmosis is necessary to apply external pressure to a solvent, usually water. Water passes through the membrane towards a lower concentration of the solution and is thus purified. Dissolved substances settle in the solution, increasing their concentration. With the help of pressure, in this case, two tasks are solved at once:
1) Pressure stops direct osmosis, and in its absence, the direct osmosis process inevitably begins to function.
2) With the help of pressure, the productivity of the installation is increased.
The amount of external pressure directly depends on the conditions and purposes of use. The higher the external pressure, the higher the filtration rate. In order to purify water in the plumbing system, the pressure should be 3 - 3.5 atm. In the event that it is necessary to resort to desalting sea water, the pressure will be in the range of 70 - 80 atm. In practice, a special pump (pump) is used to obtain the required pressure.
Reverse osmosis system - application :
1) Reverse osmosis system for water desalination.
2) Reverse osmosis system for water purification from all kinds of impurities in industry and everyday life.
3) The reverse osmosis water purification system makes it possible to obtain ultrapure water for medicine.
4) The reverse osmosis water purification system is used in the food industry.
5) The reverse osmosis desalination device is used on large ships and submarines.
6) The reverse osmosis system is necessary in heat and power engineering for water treatment systems.
The reverse osmosis system found its use in 1970 and was the most common in water purification by reverse osmosis. This system is divided into two types: for household appliances and industrial systems. These two groups have a lot in common (osmosis and water purification are inextricably linked). All systems are implemented in the form of several modules, each of which performs specific functions.
This is explained by the following :
A) All modules have different service life, therefore, replacement takes place at different times.
b) Mechanical impurities more often clog the membrane, therefore this filter must be replaced first.
The reverse osmosis system does not remove all impurities; chlorine is especially unpleasant and dangerous, which destroys membranes. Chlorine is removed by installing 1-2 carbon filters, which are placed after the mechanical water purification filter. Also, this filter removes all organic compounds and iron (it is dangerous for membranes).
After the reverse osmosis filter, a mineralizer is usually installed, which allows you to add the necessary minerals and salts, but removed by the filter. Further, the purified water is treated with ultraviolet light, which makes it possible to rid it of microorganisms by 100%.
The reverse osmosis installation diagram is as follows: mechanical water purification filter --- carbon filter for water purification # 1 --- carbon filter # 2 --- reverse osmosis water purification filter --- mineralizer --- sterilizer (UV). The number of cleaning stages can be up to 6-7. As a result of cleaning, the water is divided into two channels:
A) Purified water enters household systems and consumers, or into a water storage tank.
b) Water (brine) with a high salt content is discharged into the sewer system.
A reverse osmosis water filter is a reverse osmosis membrane. Modern membranes are made from a synthetic polymer composite material.
The surface membrane creates a special layer of water that does not dissolve the salts that it contains, and also prevents them from passing through it. Depending on what the membrane is intended for, the method of its execution (plate or roll material) depends.
By its design, the membrane of a reverse osmosis water purification filter is a porous structure made of composite material. The main requirement is that the membrane must pass only water through itself, while retaining dissolved impurities. For water, the pore diameter should be 0.0001 microns, but for substances such as chlorine, oxygen and fluorine, it is not an obstacle.
The reverse osmosis membrane has two main parameters, such as the degree of purification (99% for almost all substances) and productivity (depends on the pressure).
The reverse osmosis water purification filter purifies the first water in composition close to distilled, and the second purifies by 96-98% (from solutes) and 100% from microorganisms. The third water, despite the fact that it has high efficiency, is also not without its drawbacks.
Reverse Osmosis Water Purification Filter Advantages :
1) Has a high degree of purification
2) Has a wide range of applications
3) High performance
4) In heat power engineering, it has a low consumption during operation, when compared with ion-exchangers. Does not require regeneration and reagent stock.
Reverse Osmosis Water Filter Disadvantages :
1) It has a very high degree of purification, which in some cases requires the mineralization of purified water, especially drinking water.
2) Very sensitive to some impurities that destroy the reverse osmosis membrane (chlorine, fluorine, iron, manganese, hardness salts).
3) Pretreatment of the initial solution is required.

On the one hand, it is not difficult to install a reverse osmosis filter on your own, but in fact it is not entirely true, this requires certain skills, knowledge and tools.
Installation of a reverse osmosis filter often takes place in several stages:
You can order a standard osmosis installation by calling or pressing the button to call the wizard and fill out the form.
Under not The standard installation means: non-standard arrangement of the filter (+ 300 rubles), drank wooden passages (+ 400 rubles), the use of an additional fitting not included in the delivery set, the choice of a filter (+ 200 rubles), re-analysis of the drain line (+ 200 rubles)
Timely replacement of reverse osmosis filters is very important because this affects the quality of the water you drink and the longevity of osmosis.
You can replace the cartridges on your reverse osmosis filter on your own, but it is better to use the services of professionals in this matter. this process is not as simple as it seems initially.
Replacement of cartridges in reverse osmosis takes place in several stages:
Washing and disinfection of the clean water tank and filter housings should be done at least once every 3 years, or if foreign tastes and odors begin to appear in the treated water. Here is a detailed instruction if you decide
do the flushing of the tank in osmosis yourself.Are you not leaking water from your filter? Is water constantly running down the drain? Are there any foreign odors in the filtered water? Is your reverse osmosis filter leaking?
No matter what happened to your reverse osmosis filter, our experts will always help!
Installing a flow-through filter is not a particularly complicated process and if you have certain
With the skills and tools you can install, your flow filter, and yourself. But if you want to be guaranteed to be sure that the flow filter is installed correctly and the water is filtered as expected, then it is better to use the services of professionals in the installation and maintenance of filters.Timely replacement of cartridges (filters) in the flow filter is very important. After all, cartridges that have exhausted their resource can throw out into drinking water the dirt that they have accumulated in themselves and, in addition to just 6-12 months, a colony of bacteria begins to appear in the filter cartridge. Turning to our specialists, you will find out which cartridges, when to change and which cartridges are suitable for water purification in your region, and our experts will install the cartridges with high quality and in the required sequence.
Regeneration of cartridges is the restoration of the filtering properties of the cartridges (only those filter elements, the regeneration of which is provided by the manufacturer). Our specialists will be happy to regenerate your cartridge and it will work like new again.
If your filter for water purification has become unstable, i.e. does not pick up the tank, slowly filters, leaks, etc. In most cases, it is possible to diagnose the malfunction in the telephone mode, but sometimes this can be done only after the visit of the master to your home.
Installing a main filter is a rather laborious process that requires certain knowledge and skills, as well as the availability of a tool. Before installing the main filter, it is necessary to inspect the installation site to understand the dimensions required for installation. Next, you need to choose a place where it will be convenient to maintain the main filter in the future. Only after that the master starts installing the filter with high quality and with a guarantee.
Replacement of cartridges in the main filter.
Replacing the cartridges in the main filter is not difficult. But you need to be able to correctly replace the cartridge, because often the main filters are in a hard-to-reach place and only a qualified specialist can minimize the amount of spilled water and the likelihood of flask leakage after replacing the cartridges.
Installing filters for the whole house (softener filter, column-type filter, cabinet-type filter, high-performance reverse osmosis systems, etc.) requires a huge amount of knowledge and tools, not so much installation as setting up and running the filter. But our specialists will help you in this matter too.
This service means the replacement of the filtering load in the filter for the whole house (column or cabinet type). Replacement frequency from 12 to 60 months.
Salt delivery for filter regeneration.
We deliver salt for the regeneration of reagent filters (softeners and complex filters). The delivery cost is indicated for the quantity up to 9 bags, if you need to deliver a larger quantity, please coordinate the delivery cost with our operators.
Installation of a boost pump for osmosis
The master will install a pressure boosting kit for the correct operation of the reverse osmosis. Start up and check the correct operation of the system with a step-up pump. Also, this service implies the replacement of the current reverse osmosis pump. This work involves a household system.
Dismantling the input unit (input tee)
In cases where a transfer of the system is required, or your water filter is being replaced, or you need to replace the tee connecting your filter with the water supply, then this service will do.
Replacing the storage tank osmosis, diagnostics, pumping
When you need to set the required pressure in the storage tank of your household reverse osmosis filter, or you just need to replace it - disconnect the old one, drain the water, connect a new one, check the work (the old container is not disposed of and is not taken out by our company). This service is also suitable for installing an additional osmosis tank. You do not need to pump up a new container!
Moving a filter to another address
Rental apartment? Have you bought a new one? Are you moving? Our company is pleased to offer the service of transferring the filter to a new address. This service includes: departure of the master to the 1st address and dismantling of the old system, transportation of the filter to the new address, installation of the filter at the 2nd address. In this case, you may need to replace the cartridges with new ones, you may need some inexpensive fittings to connect. With a decrease in the filtration rate of an industrial installation, or with an increase in pressure on the membrane blocks, it is recommended to carry out a chemical cleaning of the membrane elements. Our company uses only high-quality chemistry tested by experience. The quality of the chemical flushing is very much dependent on the degree of contamination of the membrane elements, therefore we recommend not to start the chemical flushing intervals. Depending on the pollutants, we use five-stage flushing, or six-stage flushing, the time required for flushing takes one working day. This service is available at the office of our company.
