Reverse Osmosis Water Treatment Equipment, Water Filter

 Primary process is quartz sand multi-medium filter, mainly used to remove hazardous substances over 20um sediments in the water, e.g. manganese, corrosions, colloidal materials, mechanical impurities, suspended solids etc

Secondary process is active carbon filter, mainly to remove pigments, peculiar smells, biochemical organics in the water, to lower the residual chlorine value, remove pesticides and other harmful pollutants in the water.

Tertiary process is cationic resin soften of water, mainly to eliminate the hardness of water.

Quaternary process is 5micrometer aperture ultrafilter to further purify water, optimize the turbidity and chromaticity of water to accord with the inlet water requirements of RO system.

The host system of purification equipment uses RO reverse osmosis technique for desalination, the pore size of the membrane is only 0.0001 micrometer, able to remove harmful resolvable solids, bacteria and viruses etc. The desalinization rate is above 99.6%, providing purified water conforming to state standards.

The pasteurization normally choose ultravoilet or ozone for sterilization of water, all the bacteria can be exterminated within 0.5-1 minutes. It can be applied for sterilization and smell-removing.

Normal tap water can reach a conductivity of below 10 µs/cm after RO reverse osmosis filtration, the desalinization rate is between 90-99%. For lower conductivity, or conductivity of raw water is beyond 500 µs/cm, secondary reverse osmosis can be introduced, the conductivity of outlet water is under 5 µs/cm. With EDI continuous deionization and anion-cation exchange mixed bed, the conductivity will be under 1 µs/cm.
