RO reverse osmosis is a key component of pure water treatment equipment. After preparation and treatment, the source water specified by the reverse osmosis membrane is transformed into pure water after RO reverse osmosis filtration. Therefore, it is important to ensure the quality of pure water in the maintenance and upkeep of RO reverse osmosis.

The phenomenon where the salt content on the surface of a reverse osmosis membrane is higher than the concentration value in the main liquid during the entire process of operation is called channel effect. The adverse effect of channel effect is that some salts deposit on the surface of the membrane, blocking the safe channel for reverse osmosis membrane water production and reducing the membrane water production rate. When the organic matter in the water supply is not continuously washed away or cleaned off on time, it will accumulate on the surface of the membrane, especially some positively charged reverse osmosis membranes that attract energized organic matter and stick it to the membrane surface.

The accumulation of organic matter on the membrane surface poses a more serious threat to the membrane than the deposition of salt on the membrane surface, and sometimes such harm is inevitable. The concentration values of organic matter and various acid salts on the surface of the membrane are much higher than those of the flowing water, which provides rich and colorful nutrients for the breeding of pathogens.

Many microbial communities not only block the safe pathway for water production, but also due to the fact that reverse osmosis membranes themselves are organic matter, they can be dissolved by microorganisms, leading to inevitable damage. Reducing chemicals such as permanganate index in water aggregate on the membrane surface. When they reach a certain level and exceed the concentration that the membrane itself can bear, the reverse osmosis membrane will undergo oxidation and decomposition.
