The ultra-pure water system for the electronics industry is a refined water system using electronic technology. It desalinates the raw water according to the water quality index of the raw water. The advanced and mature reverse osmosis desalination device with stable effluent quality and stable system operation is selected as the main desalination equipment of the system. At the same time, the system has good economy. Electrolytic capacitors Production of aluminum foil and cleaning of working parts The production screen of the water liquid crystal display needs to be cleaned with pure water and the pure water is used for the production of the liquid crystal. The transistor is mainly used for cleaning the silicon wafer, and a small amount is used for the preparation of the liquid and the high-purity water in the production of the integrated circuit to clean the silicon wafer, etc.
1. Pretreatment system - reverse osmosis system - intermediate water tank - coarse mixed bed - fine mixed bed - pure water tank - pure water pump - ultraviolet sterilizer - polishing mixed bed - precision filter - water object (≥18MΩ.CM) (traditional craft)
2. Pretreatment - reverse osmosis - intermediate water tank - water pump - EDI device - purified water tank - pure water pump - ultraviolet sterilizer - polishing mixed bed - 0.2 or 0.5μm precision filter - water object (≥18MΩ.CM) (Latest technology)
3. Pretreatment - first stage reverse osmosis - dosing machine (PH adjustment) - intermediate water tank - second stage reverse osmosis (positive charge reverse osmosis membrane) - pure water tank - pure water pump - EDI device - ultraviolet sterilizer - 0.2 or 0.5μm precision filter - water object (≥17MΩ. CM) (the latest technology)
