Reverse osmosis equipment cleaning method

Jan 27, 2020

Under normal operating conditions, the reverse osmosis membrane may also be contaminated with inorganic scale, colloids, microorganisms, metal oxides, etc. These substances deposited on the surface of the membrane will cause a decrease in the output of the reverse osmosis device of the water purification equipment or a decrease in the desalination rate and pressure difference The increase may even cause irreversible damage to the membrane. Therefore, in order to restore good water permeability and desalination performance, the membrane needs to be chemically cleaned.

Generally, it is cleaned every 3 to 12 months. If you have to clean it once a month, it means that the pretreatment system should be improved and the operating parameters adjusted. If it needs to be cleaned once every 1 to 3 months, it is necessary to improve the operation level of the equipment. It is difficult to judge whether it is necessary to improve the pretreatment system.
