Reverse osmosis element membrane cleaning cycle

Author:Huamo Water treatment materials FROM:Water filter membrane manufacturer TIME:2021-12-10

Whether you use osmosis membrane filter or other dissolved air flotation equipment, these machines require regular maintenance. If it is not maintained, various problems will appear after a long period of time, and the damage rate will be accelerated. For the maintenance of the machine, the most important thing is to clean and replace reverse osmosis element membrane.

reverse osmosis element membrane

1. Features of reverse osmosis element membrane

①. The source of raw materials for film making is simple, the production and processing are simple, and the cost is low.
②. Has high impact toughness and service life.
③. It can fully play its role under the lower actual operating burden.
④. It should have high efficiency under high flow rate.
⑤. Can withstand the hazards of organic chemistry or biochemical functions.

⑥. Less harmful by PH value, temperature and other factors.

2. Cleaning cycle of reverse osmosis element membrane

After a period of application, residues are adsorbed on the surface of reverse osmosis element membrane, which leads to clogging, resulting in a decrease in permeability coefficient, generation of bacteria, corrosion and damage to the membrane. Therefore, it should be cleaned as soon as possible. Generally, it should be cleaned under the following conditions:
. The main parameters of water seepage increase significantly within a certain period of time and must be cleaned.
. When the water seepage temperature is constant, the working pressure at the inlet and outlet of the high-pressure pump is increased by more than 5-8% to ensure that the membrane diffusion coefficient remains unchanged and must be cleaned.
. After a period of application, if it is more than half a year, it must be cleaned.
In addition, reverse osmosis element membrane must be replaced every 2-3 years.

When osmosis membrane filter occurs in the above situation, it indicates that the reverse osmosis membrane must be cleaned. Of course, the cleaning cycle does not need to be too frequent. Excessive cleaning will also cause the characteristics of the membrane to decrease, so as to affect the final use effect. It is necessary to carry out regular cleaning in accordance with the above description.
