Pure water extraction equipment how often to replace the filter media supplies

The osmosis device mainly includes multi-stage high-pressure pumps, reverse osmosis membrane elements, membrane shell (pressure vessel), bracket and other components. Its main role is to remove impurities in the water, so that the water to meet the requirements of use. In order to make the reverse osmosis water purification equipment long life, it is necessary to regularly maintain it and replace consumables. Reverse osmosis water equipment consumables mainly include quartz sand, activated carbon, softening resin, PP cartridge, reverse osmosis membrane

Quartz sand: quartz sand filter media in reverse osmosis water equipment to play a role in filtration, like water through the gravel penetration into the ground, used to retain suspended solids in the water colloids and other particles impurities, mainly for those fine suspended solids, so as to play a filtering role.

Normal service life is about 8-24 months. Quartz sand are used quartz sand, pure white color, quartz sand filter media in strict accordance with the standard production and processing of filter media for water treatment.

Activated carbon: the normal service life of 8-24 months or so, the role is mainly to remove macromolecules of organic matter, iron oxides, residual chlorine. Activated carbon has the ability to retain suspended solids from the surface area provided by the activated carbon. When the flow rate is low, the filtration capacity of the reverse osmosis water purification equipment mainly comes from the sieving effect of activated carbon, while the flow rate is fast, the filtration capacity comes from the adsorption effect on the surface of the activated carbon particles, in the filtration process of the activated carbon particles provided by the surface area of the larger, the stronger the adhesion to the suspended matter in the water.

Softening resin: softening resin normal service life of about 8-24 months. Cation exchange resin is a polymer with corresponding functional groups. In general, the conventional sodium ion exchange resin with a large number of sodium ions. When the content of calcium and magnesium ions in the water is high, the ion exchange resin can release sodium ions, functional groups and calcium and magnesium ions combined, so that the content of calcium and magnesium ions in the water is reduced, the hardness of the water decreases, and the hard water becomes soft water.

PP cotton cartridge: replacement cycle: the normal service life of 10-30 days or so, the use of precision filters in the incoming water residual suspended solids, non-curved particles and colloids and other substances removed, so that the RO system and other subsequent equipment to run more safely and stably.

RO membrane: replacement cycle: the normal service life of about 3-5 years. Reverse osmosis RO membrane is generally made of polymer materials. The diameter of the surface microporous generally between 0.5 ~ 10nm, the size of the permeability is related to the chemical structure of the membrane itself
