1, Salt water purifier​ Quartz sand filter

Quartz sand filter mainly removes suspended solids, colloids, sediment, clay, rot plants, particulate matter and other impurities in water, reduces

the turbidity of water, and achieves the purpose of water quality clarification. After treatment, the water pollution index SDI≤4 can prevent

membrane Surface fouling (including CaCO3, CaSO4, SrSO4, CaF2, SiO2, iron-aluminum oxide, etc.), prevention of fouling of colloidal

substances and suspended solid particles, prevention of fouling of organic substances and microorganisms, and protection of reverse osmosis

membranes.

2, Salt water purifier​ Activated carbon filter

Activated carbon filter mainly uses activated carbon to have a large number of functional groups such as hydroxyl and carboxyl groups, which

can chemically adsorb substances of various natures to remove odor, organic matter, colloid, iron and residual chlorine in water, and reduce

the color and turbidity of water. , reduce pollution to reverse osmosis, residual chlorine after treatment ≤ 0.1ppm

3. Salt water purifier​ Softening device

The sodium ion on the ion exchange resin exchanges calcium and magnesium ions in the water to reduce the hardness in the water while

regenerating the ion exchange resin with the salt.

4, Salt water purifier​ Security filter

The 5 micron polypropylene wound fiber filter is used as the filter element, mainly to remove the particles of more than 5 micrometers that have

not been removed by the pretreatment system, and to remove the filter material lost before the treatment, thereby protecting the RO membrane

from being less polluted. Whether the filter element can reach normal use conditions will affect the normal working conditions of the membrane.

5, Salt water purifier​ Reverse osmosis system

Including high pressure pumps, reverse osmosis membranes, membrane shells, cleaning systems and related piping, valves, measuring

instruments, etc. The reverse osmosis membrane adopts the ULP series ultra-low pressure composite membrane element which is imported

from American Dow Company. The first-stage desalination rate is above 99%, and the reverse osmosis water conductivity is less than 15μS/cm.

The reverse osmosis membrane element is compounded by a three-layer membrane, the surface layer is made of aromatic polyamine, and has

a thickness of about 2000 angstroms and is supported by a layer of microporous polysulfone layer, which is resistant to mechanical tension and

chemical attack. The assembly has a large membrane area of ​​370 feet and a relatively large water production flux.
