I. Features of ultrapure water equipment for cosmetics

Pure water equipment for cosmetics production: the clean and sterile water is the foundation of skin care products in cosmetics industry, according to the standards of water for cosmetics industry, the pure water equipment has been researched and developed which is suitable for cosmetics industry. Due to different water sources, different technologies and equipment configurations have been adopted to meet the standards of cosmetics industry, we usually adopt double-stage RO or single-stage RO+ mixed bed, single-stage RO+EDI, the representative equipment is showed as follows (the specific equipment configurations can be configurated based on the water quality provided by clients.)

II. Technology processes of ultrapure water for cosmetics

1. Double-stage RO

Raw water ---raw water booster pump ---multi-media filter ---activated carbon filter ---water softener ---precision filter ---first-stage RO---PH regulation ---middle water tank ---second-stage RO (surface of RO membrane with positive charge) ---purification water tank ---pure water pump ---micropore filter ---water-use point
2. EDI

Raw water ---raw water booster pump ---multi-media filter ---activated carbon filter ---water softener ---precision filter ---first-stage RO ---middle water tank ---EDI ---micropore filter ---water-use point

3. Ion exchange

Raw water ---raw water booster pump ---multi-media filter ---activated carbon filter ---water softener ---precision filter ---cation resin filtration bed ---anion resin filtration bed ---anion and cation resin mixed bed ---microfilter ---water-use point
