The following are common causes of malfunctions and how to resolve them.

Water from the system is always drained into the sewer

To verify this, you must first close the tank - turn the lever under the sink 90 degrees relative to the pipe. If after half an hour the water also goes into the drainage, you need to look for the reasons:

• For proper operation of the system, a pressure of 3-4 atmospheres is required. If it is higher, then it is better to purchase a gearbox that aligns it. With low pressure, put the pump.
• Membrane reverse osmosis normally, it should pass water in a thin stream - no thicker than the little finger. Otherwise, it should be replaced;
• The 4-way valve stops the flow of water into the tank if the tap is closed. When this does not happen, a new valve is required;
• The check valve of the system must prevent the water from draining when the tank is full. Needs to be replaced if it does not perform its function.

Purified water has an unpleasant taste

The most common cause is stagnation of water in the cleaning cartridges or in the tank itself. In the first case, it is necessary to drain about 1 liter of water before use, or use a bioceramic cartridge daily.
If the taste of water is still unpleasant, then the water has stagnated in the tank. The post-carbon cartridge needs to be replaced urgently. Or completely renew the water in the tank, which must be done monthly. In general, it is worth calculating the estimated water consumption - for two people, an 8-liter tank is enough.

Weak water pressure from the system faucet

Perhaps this is due to the operation of the tank itself, because the cleaning system is slow and for a large number a reservoir is required. If there is no water in the tank, the reverse osmosis water filter works in vain. You should check if there are any obstacles to the water supply to the tank, fully open the tap to it. If everything is in order, then the tank itself is faulty.

Water is not drawn into an empty tank

The reason may be in the pressure, which can be increased with a pump.

Water does not flow when the tank is full

You should check the serviceability of all taps - if everything is in order, then the pressure inside the tank is too low. Outside, on the side of the tank itself there is a cap, under it there is a nipple for air supply. You can thus pump up the pressure up to 1 atmosphere.

Slowly draws water from the tap of the system

Main reasons:

• The time has come to replace the filter - due to heavy pollution, the water passes through the system too slowly;
• Low water pressure in the system. Again, you need to install a pump.
• The membrane in the system is faulty;
• Blockage in the filtration departments after the membrane. When water flows normally up to the membrane, it is necessary to clean all parts of the filter after it.

The main criteria that should be considered for the correct operation of the reverse osmosis system

To prevent system malfunctions, important aspects must be considered before installation:

1. Hardness of water;
2. General mineralization of water;
3. Pressure (3-4 atm);
4. t ° of water when supplying (from 15 to 25 degrees)

Standard installation of a reverse osmosis filter - now free of charge! (for models more expensive than 8500 rub., for osmosis models up to 8500 rub. installation = 500 rub.)

On the one hand, it is not difficult to install a reverse osmosis filter on your own, but in fact this is not entirely true, this requires certain skills, knowledge and tools.

Installing a reverse osmosis filter often takes place in several stages:

1. The master inspects the installation site of the filter and the faucet for clean water.
2. Next, you need to check the water pressure in the water supply. for correct operation osmosis without a pump requires a pressure of at least 2.7 atmospheres. If the pressure in the water supply is less than this indicator, you must either upgrade your osmosis by installing a more efficient membrane or a pump to increase pressure.
3. Next comes the preparatory assembly of the filter and checking the tightness of all connections.
4. After the osmosis is assembled, the master mounts a faucet for clean water at your sink (in a place agreed with you, taking into account the recommendation of the master).
5. Next, a tie-in to the water supply is mounted (a tee with a faucet that cuts off the water supply to the filter).
6. After having passed preparatory work the master connects all filter nodes to each other.
7. Next, the master proceeds to start the filter and flush the pre-treatment water cartridges.
8. After the filter is started, the master again checks the tightness of all nodes and, using a TDS meter, checks the correct operation of the filter.
9. After the osmosis is installed and the master is 100% sure that it is working correctly. The master teaches you how to properly operate your filter, fills out a warranty card.
10. When all the work is completed, the master fills out the warranty card and you pay for his services.

You can order a standard osmosis installation by calling the phone or by pressing the button to call the wizard and fill out the form.

Under not standard installation means: non-standard filter arrangement (+300 rub.), drank wooden passages (+400 rub.), use of an additional fitting not included in the delivery set, filter selection (+200 rub.), re-analysis of the drainage line (+200 rub.)

Replacing filters in reverse osmosis.

Timely replacement of filters in reverse osmosis is very important. this affects the quality of the water you drink and the longevity of the 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 at first.

Replacing cartridges in reverse osmosis occurs in several stages:

1. First of all, the master checks the correct operation of the reverse osmosis membrane with a TDSmeter (a device that is designed to test water quality) and if the TDS meter readings are high, then it is necessary to replace the reverse osmosis membrane.
2. Next, there is a replacement of 3 cartridges for pre-treatment of water, a post-filter (aka post-carbon) and a mineralizer, if the time for replacing these modules has come.
3. After the new cartridges are installed, the master flushes these cartridges, eliminating the clogging of the membrane with coal dust.
4. Next, the filter is launched into working condition.
5. After the filter is started and the master is sure that your filter is working correctly, he makes notes in the passport of your osmosis and you pay with it.

Tank flushing, for clean water, in a reverse osmosis system.

Rinsing 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 purified water. Here detailed instructions if you decideDo your own tank rinsing with osmosis.

Reverse osmosis system repair.

Is your filter leaking water? Is the water constantly running down the drain? Foreign odors in filtered water? Is your reverse osmosis filter leaking?

No matter what happened to your reverse osmosis filter, our experts will always help!

Installation of a flow filter for drinking water.

Installing a flow filter is not a particularly complicated process and if you have a certainWith your skills and tools, you can install your flow filter, and on your own. But if you want 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.

Replacement of cartridges in the flow filter.

Timely replacement of cartridges (filters) in the flow filter is very important. After all, cartridges that have exhausted their resource can be thrown away, in drinking water the dirt that they have accumulated in themselves, and in addition, after only 6-12 months, a colony of bacteria begins to emerge in the filter cartridge. By contacting our specialists, you will find out which cartridges, when you need to change them, and which cartridges are suitable for water purification in your region, and our specialists will install the cartridges in a high-quality manner and in the right sequence.

Regeneration of cartridges.

Regeneration of cartridges is the restoration of the filtering properties of cartridges (only those filter elements, the regeneration of which is provided by the manufacturer). Our specialists will gladly regenerate your cartridge and it will work like new again.

Diagnostics (filter failure detection).

If your water filter has become unstable, i.e. does not fill the tank, slowly filters, leaks, etc. In most cases, it is possible to diagnose a malfunction over the phone, but sometimes this can only be done after the wizard visits your home.

Installation of the main filter.

Installing the 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 service the main filter in the future. Only after that the master proceeds with the installation of 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 replace the cartridge correctly, 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 the flask leaking after replacing the cartridges.

Installation of a filter for the whole house.

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 experts will help you in this matter.

Replacement of the filter loading.

This service refers to the replacement of the filter load in the filter for the whole house (column or cabinet type). The frequency of replacement is from 12 to 60 months.

Delivery of salt for filter regeneration.

We deliver salt for the regeneration of reagent filters (softeners and filters of complex cleaning). The shipping cost is indicated for a quantity of up to 9 bags, in cases where a larger quantity is needed, 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 reverse osmosis. Start up and check the correct operation of the system with a booster pump. This service also includes the replacement of the current reverse osmosis pump. This work provides a domestic system.

Dismantling the inlet assembly (inlet tee)

In cases where the transfer of the system is required, or your water filter is being replaced, or you need to replace the tee connecting your filter to the water supply, then this service is suitable.

Replacing the osmosis storage tank, diagnostics, pumping

When it is required to set the required pressure in storage capacity your household reverse osmosis filter, or you just need to replace it - turn off the old one, drain the water, connect a new one, check the operation (the old container is not disposed of and is not taken out by our company). This service is also suitable for installing an additional tank for osmosis. There is no need to pump up a new container!

Moving a filter to another address

Rental apartment? 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 a new address, installation of the filter at the 2nd address. In this case, you may need to replace the cartridges with new ones, some inexpensive fittings may be required to connect. By reducing the filtration rate industrial plant, 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 proven by experience. The quality of chemical flushing depends very much on the degree of contamination of the membrane elements, so we recommend that you do not run chemical flush intervals in time. Depending on the contaminants, we use five-stage washing or six-stage washing, the time required for washing takes one working day. This service is available at our office.

- operating principle and application

Osmosis is an integral part of the life of living organisms and plants. Which provides metabolism at the cellular level. In this article, we will look at 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 in the direction of its lowest concentration. If there were no membrane, then the vessel would simply have an equalization of concentration. Transfer is caused by osmotic pressure. The pressure, as a rule, depends on the type of solvent, composition and concentration of dissolved impurities.

Reverse osmosis is required to apply external pressure to a solvent, usually water. Water passes through the membrane towards a lower concentration of the solution and is thereby purified. Solutes settle in solution, increasing their concentration. With the help of pressure in this case, two problems are solved at once:

1) Pressure stops direct osmosis, and in its absence, the process of direct osmosis inevitably begins to function.
2) With the help of pressure, the productivity of the installation increases.

The magnitude of the external pressure directly depends on the conditions and purposes of the application. The greater the external pressure, the greater the filtration rate. In order to purify the water plumbing system, the pressure should be 3 - 3.5 atm. In the event that it is necessary to resort to desalination of sea water, then the pressure will be in the range of 70 - 80 atm. In practice, a special pump (pump) is used to obtain the necessary 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 applied in the food industry.
5) The reverse osmosis desalination device is used on large ships and submarines.
6) A reverse osmosis system is necessary in the thermal power industry for water treatment systems.

The reverse osmosis system found its application in 1970 and was the most common in reverse osmosis water treatment. This system is divided into two types: for household appliances and industrial systems. These two groups have much in common (osmosis and water purification are inextricably linked). All systems are implemented in the form of several modules, each of which performs certain functions.

This is explained by the following :

A) All modules have a different service life, in connection with this, the replacement takes place at different times.
b) Mechanical impurities clog the membrane much more often, so this filter must be replaced first.

The reverse osmosis system does not remove all impurities; chlorine, which destroys membranes, is especially unpleasant and dangerous. Chlorine is removed by installing 1-2 carbon filters, which is placed after a mechanical water purification filter. Also, this filter removes all organic compounds and iron (which is dangerous for membranes).

After the reverse osmosis filter, as a rule, a mineralizer is installed, which allows you to add the necessary minerals and salts removed by the filter. Further, the purified water is treated with ultraviolet light, which makes it possible to rid it of 100% of microorganisms.

The scheme of reverse osmosis installation is as follows: mechanical water purification filter --- carbon filter water purification No. 1 --- carbon filter No. 2 --- filter reverse osmosis water purification --- mineralizer --- sterilizer (UV). The number of cleaning steps can be up to 6-7. As a result of purification, 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.

The 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 are present in it, and also prevents their passage through it. Depending on what the membrane is intended for, the method of its execution (plate or roll material) depends.

By its design, the reverse osmosis water purification filter membrane is a porous structure made of a 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 µm, 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 performance (depends on pressure).

The reverse osmosis water purification filter purifies the first water in composition close to distilled, and the second purifies 96-98% (from dissolved substances) and 100% from microorganisms. The third water, despite the fact that it has high efficiency, is also not without 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 thermal power engineering, it has a low consumption during operation, when compared with ion exchangers. Does not require regeneration and a supply of reagents.

Reverse osmosis water purification 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 necessary.

The principle of operation and scheme of reverse osmosis filtration

Don't even open

There will be no photo of the parcel, pimples, tracks and other crap. Mail works! All parcels to me in Moscow reach a maximum of a month and a half.

Recently, a colleague contacted me with a request to help/see the purchased OO filter. She was worried about the constant noise under the sink. I already knew the answer :(
background
This was about seven years ago.
In order not to buy bottled water (expensive) installed in the office
Everything would be fine, but after about a month I noticed that the system was constantly making noise, i.e. there is a constant discharge of water into the sewer, even when storage tank full.
I began to understand, it turned out that the matter was in the ill-fated membrane (sometimes it is also called a crab, in the review mentioned above, the TC mistakenly called it an auto switch)
As soon as he did not try to treat: he pasted adhesive tape and bicycle patches. Didn't help.
I had to change the whole crab, but a month later the membrane broke again. Dog The problem was buried in the high water pressure in the system.
It was then that the idea of ​​\u200b\u200bmodernizing this node came to mind.
First a little theory
It is known that the OO membrane works best at high water pressure in the system (this is what models with a pump are sold for). If the pressure in the system is less than 3 atm, then water simply will not be forced through the pores of the membrane and will flow into the sewer.
But if the water pressure is too high, then, as happened in my office, the membranes in the cut-off valve simply will not withstand.
The valve works according to the following principle:
While the storage tank is empty, there is no pressure in the "clean water line". But as soon as the tank is at least half full, the (conditionally) upper large membrane starts working and through the pusher begins to put pressure on the lower small membrane of the “dirty line” (filter inlet), thereby closing the incoming flow. And as soon as the tank is filled, the upper membrane completely presses the lower one, which blocks the inlet flow.
But with the gradual filling of the tank, the inlet pressure drops and, accordingly, the efficiency of the filter.
It was decided to kill two birds with one stone: get rid of the problematic "crab", and increase work efficiency / filling speed / reduce water consumption.
Implementation
Removed crab. Instead of him
a/ put in a clean line .
b/ at the entrance of the system to a dirty highway put
s / connected to the chain 220v-relay-EM valve.
I bought (for convenient placement of the valve) tubes and 4 plastic fittings for the relay and the EMC valve.
The result completely satisfied: Nothing is torn, excess does not leak into the sewer, the effective operation of the membrane throughout the entire process of filling the storage tank and the speed of full filling.
The only negative - you need 220v.
Let's go back now
Since I already knew the answer to the problem, it only remained to find spare parts for repairs. I didn’t find it in my city, therefore, having warned a colleague that “it’s not going to be done soon”, I got on eBay.
And found!
According to the parameters on the seller's page:
Material: Brass
Power: 220v
Type: Normally (i.e. without voltage) closed
Max pressure: 1.0MPa (10atm)
For water
Were also purchased (but already in local stores), and
(I provide links to eBay for help on how to search if you can’t find it in local stores)

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 the presence of microcracks, the integrity of the gaskets, etc.
2) After 3-4 years, I recommend replacing all three lower plastic flasks (twice I had cases when the flask pulled out along with the thread, it bursts top part). The solenoid valve, if installed before entering the system, will save your apartment from the flood!
3) I recommend installing the solenoid valve at the inlet of the first mud filter (in most systems, the crab is set to a cut-off between the first and second filters) See p2!
4) UPD! A very common mistake: "inflate" the storage tank! Many people think that by pumping up, they will raise the pressure in the filter. Yes, they will raise it, but not in the filter, but in the tank itself. As a result, less water will be filtered into the tank.
A rubber bulb is built into the storage tank, which 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. The storage tank is labeled with the operating pressure (100psi=6.9atm). This is what should be left!
5) UPD! Another common mistake: replacing the "crab" in the hope that it will raise the pressure. Any new "crab" (as it is arranged) with the gradual filling of the storage tank GRADUALLY reduces the inlet pressure to the filter. The solution 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 stream 1-2 mm thick.
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 consumption of water.
If the trickle is very thin or dripping, then the RO membrane may be clogged.
Or maybe the pressure in the water supply is really low. But here you can’t cure it with any settings, just set it. But such an upgrade is quite expensive (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 a little worse. It is placed in the same housing as the OO membrane. And the storage tank and all the piping of the OO are removed ( check valve, crab, flow restrictor).

I didn’t plan to do a review, I wrote in a hurry

The reverse osmosis system constantly drains water into the sewer.

Check if this is true. 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 still drains into the drain, it's either pressure, or the reverse osmosis membrane, or the valve after the reverse osmosis membrane, or the four-way valve.

Shut off the tank and open the faucet that is installed on the sink. Reverse osmosis should purify water bypassing the tank. If the flow of purified water is small, about the thickness of a pen shaft, the membrane is working properly.

Check the outlet water pressure just before the reverse osmosis membrane. If the pressure is greater than 6 atm. wait until your home's water supply pressure equalizes, or install a pressure reducer. The cost of the reducer that equalizes the pressure from 250 UAH. up to 350 UAH depending on the country of manufacture. The reverse osmosis system requires a pressure of 3 - 4 atm. If the water pressure is less than 3 atm, install a pump, the cost of a pump kit 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 block, replace the four-way valve (cost 69 UAH).

With a faulty non-return valve, the tank with purified water is full, but the discharge of water into the drain does not stop. Replace the check 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 it is most likely that the water is stagnant. Complaints about the bad taste of water after additional upper mineralizer cartridges or bioceramic cartridges are not related to the fact that these filters bring something to the water, but to improper operation of the water filter. There are up to three glasses of water in the water treatment cartridges. This water, like the water stored in the tank, must not be allowed to stagnate. To eliminate extraneous taste and smell, 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 faucet valves, or in cases where a mineralizer is not installed), water does not stagnate in filter cartridges, but in a water tank. Here, the most common cause of the problem is that the period for replacing the post-carbon cartridge was missed (once a year), or the resource of the tank (hydroaccumulator) was not fully used. If you cannot use the entire volume of the filter during the operation of the filter (tanks are available with a capacity of 15l. - 12l., 11l.-8l. and 8l.-6l.), 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 fill up a large container or simply drain all the water from the tank into the sewer. If 1-2 people will use the filter, the smallest tank (8l.) is recommended during installation.

Low pressure from a faucet in a reverse osmosis system. Low pressure from the water filter faucet is most likely due to improper operation of the tank. The speed 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 collect a large vessel or at least a glass, a storage tank (hydraulic accumulator) is provided in reverse osmosis systems. If no water enters the tank, the filter runs idle. When you open the faucet, water squirts and immediately flows in a trickle. If nothing interferes with the flow of water into the tank (the tubes are not pinched and the tap on the tank is open), then the problem is that the tank is not working properly.

The tank is empty and no water flows into it. Open the faucet on the tank by turning the lever on the faucet (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 your home's water supply pressure equalizes, or install a pump. The cost of a pump-action kit for increasing pressure for a water purification filter is from 1500 UAH. up to 2000 UAH depending on the country of manufacture.

The tank is full and no water comes out of it. Open the faucet on the tank by turning the lever on the faucet (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 that must be drawn in and out of the tank, then the point is the internal pressure of the water tank. If the tank was originally working, and it was not subjected 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 an ordinary nipple for pumping air, the same as on the tires of a car or bicycle. Pump up the pump to a level of 0.5 - 1.0 atm. If the water tank still does not fill or dispense water, replace the tank. The cost of an iron tank for water 8 liters 570 UAH.

reverse osmosis system slowly picks up water. Open the faucet on the sink. If the flow of water is small, about the thickness of a pen shaft, reverse osmosis works fine. Check the degree of soiling of the pretreatment 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-filter 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 equalizes, or install a pump. The cost of a pump that increases pressure is 1500-2000 UAH. Press the ring against the fitting in front of the post-carbon cartridge and pull out the hose. If the flow of purified water is as thick as a pen shaft, then there is a mechanical blockage on the way from the reverse osmosis membrane to the faucet. Step by step check all connections of the water filter after the membrane. If the flow of purified water occurs drop by drop, then the reverse osmosis membrane, due to the service life, or the deterioration in the quality of the water supplied to it, has failed. The cost of a reverse osmosis membrane is from 350 UAH. up to 700 UAH depending on the rate of purification of the reverse osmosis membrane.

The correct operation of a reverse osmosis system as well as its performance depends on several variables:

1. The quality of the incoming water (the norm of total mineralization is 200-500 ppm =<1500 мг/л, норма жесткости воды <10 мг-экв/л)
2. Incoming water pressure (norm 3 - 4 atm)
3. Inlet water temperature (standard 15 °C - 25 °C).

So, for example, when the quality of incoming water deteriorates (high total mineralization of more than 500 ppm) and its temperature decreases (in winter, the 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. For lower pressures, a pressure booster 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 WORK EFFICIENTLY.

Total mineralization >500 ppm, temperature<15 °C, давление >4 atm - THE SYSTEM WORKS EFFICIENTLY.
