Installed on the water discharge pipe into the sewer after the reverse osmosis membrane. Serves to limit the flow of discharged water into the sewer. A small hole inside the part limits the discharge of water from the membrane into the sewer and, due to increasing pressure, the reverse osmosis process itself occurs. It has the most convenient and common quick-release connection type - John Guest. Designed for a standard 1/4" hose (Ø 6 mm).

After the reverse osmosis membrane, the flow restrictor is the most important component of the reverse osmosis system. The flow restrictor controls the regeneration of the water treatment plant (i.e. the amount of water treated compared to water discharged to the sewer). The flow restrictor must be designed in such a way that it controls cross flow around work surface osmotic membrane so that it remains clean. If the flow restrictor is small, the cross-flow velocity will be small, resulting in clogging of the reverse osmosis membrane due to sedimentation chemical substances, accumulation of pesticides, or both. But with small flow restrictors, less water goes into the drain, and this is very important for those consumers who have a small cesspool. Because the pure water separated from the incoming stream, the concentration of pollutants increases in proportion to the length of the reverse osmosis membrane. If the cross-flow rate is too low, contaminants will not be flushed from the surface of the reverse osmosis membrane.

If you want to get more performance from reverse osmosis filters, then simply installing an osmotic membrane with a higher capacity may not be effective. You will initially get increased performance, however, the RO membrane will become very clogged due to too much water passing through it and not being long enough to allow the cross flow to clean the surface of the RO membrane. This means that the flow restrictor is selected based on the performance of the installed membrane. For example, if you had a 36G membrane in your system, and you installed a 50G, then the flow limiter must be replaced from 200 to 300. Otherwise, the new membrane will not be sufficiently washed, which will shorten its service life and can lead to complete contamination.

If you initially had a 75G membrane, and you installed a 50G, then in this case it is not necessary to change the flow limiter, since the new membrane is less productive, accordingly, the old flow limiter will continue to discharge water into the sewer in the correct volume.

Limiter characteristics:

• Throughput (water flow): 420 ml/min
• Membrane matching: 75G
• Connection type: John Guest quick release
• Connection size: 1/4" (hose Ø 6 mm)
• Working pressure: up to 8 atm.

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 capable of purifying water from salts and other undesirable impurities.

The principle of water purification using reverse osmosis is 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, and its acid-base balance is normalized. The output is ultra-filtered water, completely suitable for drinking and cooking.

Increasingly larger particles of the source water are retained and sent through the reverse osmosis system to the drainage system.

What to check in a reverse osmosis system if the filter is not working correctly

Structurally, this filtration system consists of several cartridges with carbon filters and a membrane, as well as a tank for purified water.


Reverse osmosis systems, like any other filter elements, can become clogged over time, and individual elements may not work correctly, causing filter performance to decrease.

If the filter makes strange sounds, vibrates, works slowly, does not drain water, or, conversely, sends a large number of water into the drainage, you should check the following parameters:

• Water pressure in the water supply- the most common cause of reverse osmosis filter malfunctions. It should be at least 2.5-3 atmospheres (at different manufacturers different requirements to this parameter). At lower pressure, the performance of the system drops sharply - water is drawn into the tank very slowly. In this case, a large amount of water will go into the drainage.
• Passability of pre-treatment cartridges. In case of any interruptions in the operation of the reverse osmosis system, it is necessary to measure the pressure before and after the pre-filter, since clogged pre-filters reduce the pressure on the membrane.
• Tank pressure. Initially, all tanks are inflated at the factory (in an empty tank, the pressure should be in the range from 0.25 to 0.6 atm). Depending on the pressure in the water supply, it may be necessary to adjust the pressure when the tank is empty.
• Operation of the valve that shuts off the water discharge. When the tank with purified water is filled, the discharge of water into the drainage should stop. If water continues to flow down the drain, then the problem is in the valve.

Typical malfunction cases and methods for correcting them

If serious problems occur (damage to the membrane, leakage of the tank, etc.), it is required reverse osmosis repair. However, very often the faults are local in nature and you can fix them yourself.

Here is a list of the most common problems and ways to solve them:

1. Water constantly flows into the drain.

Possible reasons:

• insufficient pressure - if the actual inlet pressure is lower than what the filter manufacturer requires, then it is necessary to install a booster pump;
• Replaceable filter cartridges are clogged - they need to be replaced;
• faulty shut-off valve- if with the tap closed storage tank Even after a few minutes, water continues to flow out of the drain tube; the shut-off valve needs to be replaced.

1. Leaks.

Possible reasons:

• not a hermetically sealed connection of the tubes - the edges of the tubes are cut unevenly or they are not inserted all the way;
• loosely tightened threaded connections- check and tighten all existing nuts;
• there are no connections O-rings- install;
• high pressure (above 6 atmospheres), sudden surges - install a reduction gearbox in front of the first prefilter;

1. The tank is not filled completely.

Possible reasons:

• first connection of the system - the tank is filled within one and a half to two hours;
• cartridges and/or reverse osmosis membrane are clogged - replace them;
• clogged check valve in the flask, unscrew the membranes and rinse under running water, put them in place;
• flow restrictor clogged drainage water- make a replacement;
• too high or insufficient pressure in the tank - drain all the water from the tank and use car pump Check the pressure in the nipple with a pressure gauge. At high blood pressure in the pipeline (3.5-6 atmospheres), the pressure in the tank can be 0.5-0.6 atm. If there is no more than 2 atmospheres in the water supply, then in the tank it can be reduced to 0.25-0.4 atm. High inlet pressure can cause noise and vibration during system operation. If the pressure in the water main is below 2.5 atm, filter manufacturers recommend additionally installing a booster pump.

1. Water flows very slowly:

• low pressure on main pipeline- if the inlet pressure is lower than required according to the instructions, it is necessary to install a booster pump;
• low pressure in the tank - check and adjust;
• tubes are pinched - check, eliminate kinks;
• cartridges and/or reverse osmosis membrane are clogged - replace them;
• too much cold water at supply - operating temperature - +4-40°C.

1. From the tap water is coming white - a sign of the presence of air in the system; after a few days of osmosis operation, the problem will disappear.

1. Water after filtration has an unpleasant taste (color, smell).

Possible reasons:

• the order of connecting the tubes is incorrect - compare with the diagram in the instructions, correct if necessary;
• the membrane is clogged and/or the cartridge life has expired - replace it;
• not all the preservative is washed out of the tank - empty the tank several times and refill it again.

1. Noise and vibration during system operation, water does not flow into the drainage:

• high pressure (more than 6 atmospheres), sudden surges - it is necessary to install a reduction reducer in front of the first prefilter;
• The water flow restrictor into the drain is clogged - remove the blockage or replace the restrictor.

VIDEO INSTRUCTION

Checking the operation of the membrane

A reverse osmosis membrane may fail before its stated service life for the following reasons:

1. too contaminated source water.
2. low pressure (in this case, an excess amount of water passes through the membrane).
3. The concentrate flow limiter is faulty.

To check the performance of the membrane, you should measure the amount of water going to the drain and the amount of purified water. Considered normal Reverse osmosis efficiency 5-15%, i.e. 85-95% of the water goes into drainage.

The easiest express way to reliably check the performance of the membrane is to purchase a TDS meter. This small salinity meter, costing about 1000 rubles, allows you to find out the content of impurities in water.

After osmosis, the TDS meter should show no more than 15 units. If the indicator is higher, then the membrane is not working effectively and needs to be replaced.

The flow restrictor (restrictor) creates back pressure on the membrane to improve performance and cleaning quality. The flow restrictor must be selected for the specific membrane to prevent damage.

A water flow restrictor is an integral part of residential and commercial reverse osmosis systems. If the flow restrictor is faulty or missing, normal operation of the reverse osmosis filter is impossible.

The appearance of flow limiters may be different, but they all work on the same principle - they limit the rate of water discharge into the sewer (drainage).

Flow limiters are included with all reverse osmosis systems available on Russian market, including water treatment systems:

• Atoll
• GEYSER
• AQUAPHOR
• BARRIER

Flow limiters are available on the market with different capacities, which are usually indicated on the label. The choice of limiter directly depends on the performance of the reverse osmosis membrane.

*Membrane performance

A flow restrictor is required to create enough pressure inside the reverse osmosis system to force filtered water through the membrane.

The flow limiter operates smoothly for many years and fails very rarely. The reason the flow restrictor may need to be replaced is that over time it can become clogged and stop flowing water.

If, during long-term operation, the drainage flow limiter becomes clogged, and water with concentrated impurities stops draining into the drain, these impurities will begin to precipitate on the surface layers membrane, thus significantly reducing its service life.

If the drain flow restrictor becomes clogged, the water filtration rate will gradually decrease and the performance of the reverse osmosis system will begin to decline.

To restore normal reverse osmosis performance, a clogged flow restrictor should be replaced. The new flow restrictor should be connected to the drain line taking into account the direction of water flow. The arrow on the limiter should be directed towards the drainage hole (sewer drain).

Important!

Lack of water or low water pressure in the drinking tap may indicate more than just a faulty flow limiter. If water stops flowing into the drinking tap, this may be a sign of:

• Clogged.
• Faulty.
• Low pressure V .
• Incorrect connection.
• A combination of several factors.

To determine the exact reason for the decrease in the rate of water purification, it is necessary to check everything possible reasons, incl. pay attention to the correctness.

The flow limiters that come with them may be mentioned in information sources under other names. For example, a drainage controller or a restrictor.
