4040 Reverse osmosis membrane cleaning method type

Reverse osmosis membrane cleaning program is divided into physical method and chemical method, both methods can effectively clean the membrane.

Physical method: This method uses mechanical force to remove contaminants from the membrane surface. The whole cleaning process does not occur any chemical reaction.

Chemical method: The use of certain chemicals and the membrane surface of the filter cake chemical reaction to achieve the purpose of cleaning the membrane. 4040 Reverse osmosis membrane cleaning physical methods


—————————————————————————————————————————————————————————————————————————————————

1, manual scrubbing method

This method is relatively primitive but effective. The mother method is to gently wipe the dirt on the surface of the disassembled flat film with a soft substance (such as sponge), and rinse it off with water while wiping. This method can effectively remove a large amount of dirt on the surface of the film. But there is nothing to do with the finer impurities that penetrate deep into the membrane pores.


2, isobaric hydraulic washing method

Ultrafiltration components of any configuration can be cleaned using this method. The specific practice is to close the water production valve, open the concentrated water outlet valve, and wash the film surface by increasing the flow rate, which is effective in removing a large number of soft impurities on the film surface. The effect of isobaric flushing is also related to the frequency of continuous flushing.


3, reverse washing method

Backwash method is a method of washing from the back of the membrane (porous support layer) to the front (dense layer). This is a proven method of cleaning. After the reverse washing of the film, the isobaric hydraulic washing method is carried out, and the cleaning effect is very obvious.


4, hot water flushing method

The use of heated water (30 ~ 40~C) to wash the surface of the film, the removal of those sticky and hot soluble impurities (such as sugar) is obvious.


5, water and gas mixed cleaning method

The purified compressed air and water are sent into the ultrafiltration device, and the water-gas mixed flow will produce a violent agitation effect on the membrane surface to remove the more stubborn impurities. The effect is also better.

4040 Chemical method for reverse osmosis membrane cleaning


4040 The principle of selecting chemicals when cleaning reverse osmosis membrane: first, it can not have any chemical reaction with the membrane and other component materials, and the second is that it can not cause secondary pollution because of the use of chemicals. When using chemical cleaning methods, isobaric washing and reverse washing are often combined, which can more effectively remove contaminants on the surface of the film.


The oxidizing cleaning agent uses 1% ~ 3%H2O2, 500 ~ 1000mg/LNaCl0 and other aqueous solutions for 4040 reverse osmosis membrane cleaning, which not only removes dirt, but also kills bacteria. H2O2 is a commonly used fungicide.


Enzymatic detergent cleaning such as O.5% ~ 1.5% pepsin, trypsin, etc., in the 4040 reverse osmosis membrane cleaning to remove protein, polyessence, polysaccharide, oil pollution substances effective.


The 4040 reverse osmosis membrane element is an important component of the water treatment system, so regular 4040 reverse osmosis membrane cleaning is essential.
