Under normal circumstances,reverse osmosis element membrane can be used for about 2 to 3 years. In order to prolong the service life,reverse osmosis element membrane can be cleaned, which is usually divided into two methods: physical flushing and organic chemical flushing. Both methods can clean the membrane reasonably. Among them, physics uses the power of mechanical equipment to eliminate contaminants on the membrane surface, and the entire process does not produce all chemical changes. When physical washing cannot repair the characteristics of reverse osmosis element membrane, chemical washing should be performed.
5. Membrane damage, misalignment of the central tube of the series membrane element, and inadequate sealing of the O-ring of the pressure vessel cause the concentrated water to seep into the fresh water.
As mentioned above, the environmental pollution of ro purifier membrane is a key factor that endangers the working efficiency and service life of the reverse osmosis system. Therefore, in order to increase the service life, cleaning must be carried out.
