The ultra-pure water system for the electronics sector is a refined water system that utilizes electronic technology. It desalinates raw water based on its quality index. The system's main desalination equipment is an innovative and mature reverse osmosis device with steady effluent quality and system operation. At the same time, the system has a healthy economy. Electrolytic capacitors Cleaning operating parts and producing aluminum foil The production screen of the water liquid crystal display must be cleansed with pure water, and pure water is used to produce the liquid crystal. The transistor is mostly used to clean the silicon wafer, with a little quantity being used to prepare the liquid and high-purity water needed in the creation of the integrated circuit to clean the silicon wafer, among other things.
Typical procedure for ultrapure water in the electronics industry
1. Pretreatment system. - Reverse osmosis system - Intermediate water tank - Coarse and fine mixed beds - Pure water tank - Pure water pump - UV 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 - UV sterilizer - polishing mixed bed. - 0.2 or 0.5μm precision filter for water objects (≥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) - purified water tank - Pure water pump. - An EDI device - Ultraviolet sterilizer - 0.2 or 0.5μm precision filter - Water object (≥17MΩ. CM) (up to date technology).
4. Pretreatment. - Reverse osmosis - Intermediate water tank - Water pump - EDI device - Pure water tank - Pure water pump - Ultraviolet sterilizer - 0.2 or 0.5μm precision filter - Water object (≥15MΩ.CM) (up to date technology).
5. The standard process includes a pretreatment system, reverse osmosis system, intermediate water tank, pure water pump, coarse and fine mixed beds, UV sterilizer, precision filter, and water object (≥15MΩ. CM).
