System adopts the latest processes such as reverse osmosis and EDI. A complete set of purified water treatment process has been designed in a targeted manner. The quality of purified water meets the requirements of the current USP, EP, JP and ChP for purified water.

Pretreatment is mainly used to remove particles that may damage the film and free chlorine. The reverse osmosis process is to separate and remove the soluble solids, organics, colloidal substances and bacteria in the water by using the semipermeable spiral membrane. The raw water is sent to and passes through the reverse osmosis membrane under a certain pressure. The water passes through the tiny pore diameter on the membrane and is collected to obtain pure water. Different impurities are concentrated in the intercepting liquid and discharged. RO can remove more than 96% of dissolved solids, more than 99% of organic matters and colloids, and almost 100% of bacteria from raw water.
