Popular Science】 【common reverse osmosis equipment and solutions

The application of sewage treatment reverse osmosis equipment is more and more widely. The equipment adopts advanced reverse osmosis membrane separation technology and is an important equipment to remove most of the salt, bacteria, virus and other impurities in the raw water, and is also the key process to ensure the effluent quality of the equipment . How to ensure the better operation of reverse osmosis equipment? Here to take you to understand the reverse osmosis equipment failure and analysis.

1, booster pump, high pressure pump is not absorbent

Solution:

If the 380v voltage, check the booster pump, high pressure pump is reversed, if found to reverse the pump should be replaced by two of the three power terminals, if not reverse the need to pump the exhaust valve open deflated or Note Full of water.

220v voltage booster pump, high pressure pump will not reverse phenomenon, as long as the pump exhaust valve open deflated or to the pump body can be filled with water.

2, booster pump does not start

Solution:

First check the host whether the power to enter the thread loose, fall off, the relay is closed.

3, high-pressure pump does not start

Solution:

Check the high-pressure pump docking relay is closed, the thread plug is loose, off or water indicator light;

Such as water indicator light, indicating the source of raw water booster pump is not enough, in order not to idle high-pressure pump thus damaging the high-pressure pump, so the use of water cut off the high-pressure pump power supply protection, which play a protective role of high-pressure pump.

If sufficient water supply is provided, the pressure of the water-cut protector reaches the working pressure of the high-pressure pump, and the indicator of the water-cut protector is off to start the high-pressure pump.

4, high pressure pump abnormal sound

Solution:

Check high-pressure pump is idle, and sometimes high-pressure pump does not fully enter the water will be issued when some abnormal sound, usually 1 to 3 minutes automatically disappear, such as in 3 minutes after the disappearance of the case should be high-pressure pump exhaust Valve open, deflated or water filled.

5, pipe burst

Solution:

Due to poor water quality and impurities in some areas, or due to the long time without replacing the velvet jet filter and RO membrane cleaning, the RO membrane will be blocked, causing the pressure in the pipeline to increase, causing the pipeline to burst.

When this happens, you should first check whether the velvet filter has been cleaned or replaced, and then clean the RO membrane.

Poor quality of raw water will lead to RO membrane often blocked, then we should add ion exchange equipment or in the raw water to add scale inhibitors to eliminate impurities in water to improve water quality and increase the life of RO membrane.

6, the amount of water getting smaller and smaller

Solution:

Some device users will find out that the equipment is getting smaller and smaller (basically, this phenomenon does not occur in equipment using tap water as raw water) because some of the groundwater has poor water quality and impurities and partially clogs the RO membrane. So that equipment to reduce the amount of water.

At this time, we should periodically reprocess the pretreatment, replace the velvet filter, clean the RO membrane, or change the raw water from poor quality groundwater to tap water (in the case of tap water, configure a set of ion exchange scale System, will basically eliminate the occurrence of such phenomena).

7, pure water appears fine white or black suspended particles

Solution:

This is because the pipe is contaminated, resulting in the breeding of bacteria.

This situation should be dissolved in caustic soda into the precision filter, the operation of the valve will be closed, the pure water to the high point, start the high-pressure pump, the pure water outlet of the water flow into the precision filter cycle call 30 minutes.

Equipped with a pipe sterilizer equipment should promptly open the pipe sterilizer disinfection of pure water pipe.
