Introduction to deionized water treatment system
Deionized water treatment system is a device that uses physical and chemical methods to remove impurities such as ions, microorganisms, colors, odors, etc. from water, in order to prepare high-purity water.
Core process
- Preprocessing: including multi-media filters (such as quartz sand filters) for removing coarse particle impurities. And activated carbon filters using adsorption principles to remove discoloration, odors, and residual chlorine.
- Reverse osmosis (RO): Treatment is carried out through a high-pressure reverse osmosis membrane to further remove dissolved solids, bacteria, viruses, and other microorganisms from water.
- Mixed bed system: usually used in water treatment processes such as reverse osmosis to further improve water quality, by replacing various anions and cations in the water with anion and cation exchange resins.
- UV sterilization: Removing microorganisms from water through UV irradiation.
