According to the special requirements of water for cosmetics production, the main working principle of pure water equipment and deionized water equipment can be divided into four kinds:
1.Through the cation and anion exchange resin to obtain deionized water, then the effluent conductivity is reduced to below 10us/cm, then through the mixed bed can reach 1us/cm below. But this method cost is high, and the particle impurity is much, can not reach ideal requirement, it has been less used at present.
2.Pretreatment is the most used and popular method now.
3.The two stage reverse osmosis method.
4.Using reverse osmosis, makes the whole process pollution-free.
