Soften the resin
Cationic resin for water softening, mainly used to remove water hardness.
The hardness of water is a major calcium (Ca2 +), magnesium (magnesium 2 +) ion composition, when including raw water hardness ions through the resin layer, Ca2 + water, magnesium 2 + resin exchange adsorption, and other objects at the same time the release of Na + sodium ion mass flow from a water softener to soften water hardness ions.
In order to prevent reverse osmosis membrane fouling effectively.
Microporous membrane filter.
In water, remove particles, particle size of sand filter can remove small colloidal particles in the water, turbidity reach 1 degree, but still per ml of water for hundreds of thousands of colloidal particle size from 1 to 5 microns, the filter to remove the water pressure in 100 micron particle size or less of small particles, further reduce the turbidity,
The next process to protect the next long-running process.
