Normally use on first stage. It can remove microbes, solid sediment such as rust, sand, lime clay and jelly.
UDF/GAC Coconut shell carbon function
Normally use on second stage. It can remove chlorine, trihalomethanes, pesticides, color, smell, odor and other organic chemicals.
CTO carbon block function
Normally use on third stage. It can absorb of water color, odor, chlorine, bleach, pesticides and chemical organic pollutants and inhibit the breeding of bacteria in the activated carbon.
R.O. membrane function
0.00001UM superfine small aperture can completely remove all substances contained in the water, such as heavy metals arsenic, cobalt, cadmium, mercury and other substances, bacteria and viruses.
Resin cartridge function
The resin has exchanges ion characteristics. It absorbs and substitutes calcium and magnesium ion, which greatly reduces raw water hard degree, so as to achieve the purpose of softening. Resolving high hardness tap water brings fouling, towels hard and taste problems.
KDF (metal powder) is a high-purity copper / zinc alloy particles, it can remove chlorine and hydrogen sulfide and water dissolved lead, mercury, copper, nickel, cadmium, arsenic, antimony, aluminum and many other soluble heavy metal ions and compounds. It has outstanding performance in inhibition of bacterial, fungus, dirt, algae and microorganisms.
High pressure switch function
- High pressure switch connect with RO membrane outlet water. The function is to react tank water full or not. The started working pressure is lower than 20~25 psi. Closing pressure is 30~35 psi.
The function of low pressure switch
Low pressure switch normally connect with first stage inlet or outlet water, the function is to react whether water coming or not to first stage, the started pressure is around 5 psi.
Solenoid valve function
It’s a closed electronic controller. Once the water power start to work, solenoid valve will open and let water flowed. If tank water is full, solenoid valve will stop working to make water stop flowed.
Four ways valve function
Using water pressure to control the water, to make water not keep running. The function same as solenoid valve, but solenoid valve needs electricity, four ways valve doesn’t.
