How long to change the consumables of water treatment system(2)?

Nowadays, the water treatment equipment used in the water treatment industry is closely related to our domestic water. In order to make the service life of reverse osmosis pure water equipment longer, it is necessary to carry out regular maintenance and replace consumables. The consumables of reverse osmosis pure water equipment mainly include quartz sand, activated carbon, softened resin (after inhibitor), PP filter element and reverse osmosis membrane.

Precision filter element (5u PP cotton filter element)

Replacement cycle: the normal service life is about 10-30 days. 

The precision filter is used to remove the residual suspended solids, non straight particles,colloids and other substances in the water, so that the RO system can operate more safely and reliably.The filter element is 5um melt blown filter element. The purpose is to prevent the upper filter unit from missing impurities greater than 5um.Prevent the it enter into reverse osmosis device,then damaging the surface of the membrane, thus damaging the desalination performance of the membrane.

Reverse osmosis RO membrane

Replacement cycle: the normal service life is about 3-5 years

Reverse osmosis RO membrane is usually made of polymer materials. Such as cellulose acetate membrane, aromatic polyhydrazide membrane, aromatic polyamide membrane. The diameter of the surface micropores is generally between 0.5 nm and 10 nm, and the permeability is related to the chemical structure of the membrane itself. Some polymer materials have good salt repellency, but the water permeability is not good. Some polymer materials have more hydrophilic groups in chemical structure, so the water permeability speed is relatively fast. Therefore, a satisfactory reverse osmosis membrane should have a appropriate penetration or desalination rate. The pore size of reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms and organic matters in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and simple operation. The commonly used brands are: HYDRANAUTICS, DOW, TORAY, SAEHAN, etc.
