The process flow

1. PLC touch screen-- intelligence and color;
2. Raw water pump-- provide the pressure to quartz sand filter/active carbon filter.
3. Quartz sand filter-- get rid of silt, rust, ago, turbidity, suspended matter, organic matter, colloid, ect.
4. Active Carton filter--Adsorb the residual chlorine, smell, color, part microorganism, harmful matter, ect.
5. Softener resin--exchange Ca2+ and Mg2+ to get soft water.
6. Security filter--filtrate micro-particles, bacteria, viruses whose accuracy is larger than 5um and protect the into RO membrane, accuracy is 5um.
7. High pressure pump-- Provide the high pressure to RO membrane.
8. 1# RO membrane-- remove more than 99% ions, bacteria, salt, microorganism, heavy ions, colloid,emdotoxin and other particles in the water.
9. PH regulator-- adjust the PH of water.
10. High pressure pump--offer pressure to precision filter.
11. 2# RO membrane-- remove more than 99% ions, bacteria, salt, microorganism, heavy ions, colloid,emdotoxin and other particles in the water.
11. Precision filter--prevent microparticles whose diameter is more than 1um into EDI module.
12. EDI module-- produce 15-18.25MΩ.cm ultrapure water.
