EDI Water Treatment Plant Ultra-pure Water System For Industrial Plant
Water Treatment Equipment Description.
The methods of water treatment include physical treatment and chemical treatment.
The physical method includes the use of various filter materials with different pore sizes, and the impurities in the water are excluded by adsorption or blocking. The most important adsorption method is adsorption by activated carbon, and the blocking method is to pass water through the filter material to make the volume. Larger impurities cannot pass, resulting in cleaner water.
The chemical method uses various chemicals to convert impurities in water into substances that are less harmful to the human body, or concentrates impurities. After the impurities in the water are collected, the volume becomes larger, and the impurities can be removed by filtration.

5-Chemical industry process water: chemical cooling, fertilizer, chemical manufacturing.
6-Industrial product manufacturing water: automotive, home appliance coating, paint, paint, fine processing and cleaning, etc.
7-Boiler make-up water in power industry: thermal power, thermal power boiler, medium and low pressure boiler power system, fine chemical industry, sophisticated water use.
The ultrapure water system refers to the production system in which the system is completely produced from raw water to ultrapure water. Generally, the ultrapure water system is ultrapure water produced by multiple filtration, ion exchange, degassing, reverse osmosis, ultraviolet, ultrafiltration, nanometer rate, and ion adsorption filtration.
1: pretreatment - reverse osmosis - purification tank - ion exchanger - UV lamp - pure water pump - water point
2: Pretreatment - primary reverse osmosis - secondary reverse osmosis (positive charge reverse osmosis membrane) - purification tank - pure water pump - UV lamp - water point
3: Pretreatment - reverse osmosis - intermediate tank - intermediate pump - EDI unit - purification tank - pure water pump - UV lamp - water point
4: pretreatment→ultraviolet sterilizing device→first-level RO device→secondary RO device→intermediate water tank→EDI device→deoxidation device→nitrogen sealed pure water tank→except TOC UV device→polishing mixed bed→ultrafiltration device→water point
The water quality meets the American ASTM standard, the ultra-pure water quality standard of the electronic department (18MΩ*cm, 15MΩ*cm, 2MΩ*cm and 0.5MΩ*cm four levels)
Ultrapure water system reverse osmosis (membrane separation) method ultrapure water manufacturing technology
Reverse osmosis is the separation of the solvent (usually referred to as water) in the solution through a reverse osmosis membrane (a semi-permeable membrane) with sufficient pressure in the opposite direction to the permeation direction. Separation can be carried out using a reverse osmosis method that is greater than the osmotic pressure. , purification and concentration of the solution. The primary separation target for reverse osmosis membranes is the range of ions in the solution.
