　　1. Summary of electronics industry ultrapure water

　　Many industries need a large amount of pure water, high pure water and ultrapure water to clean semi-finished products, finished-products. They are the semiconductor, integrated circuit chip and sealing, liquid crystal display, high precision circuit board, photoelectric device, various electric device, microelectronics, large-scale and super large-scale integrated circuit. The higher integration level of integrated circuit is, the narrower line width is, the higher the requirements of water quality are.

　　According to special requirements of clients, our company uses ultrafiltration, reverse osmosis, EDI, polishing mixed bed etc. advanced technology, in order to satisfy the requirements of water quality. The production water quality can reach all the index and standards of national electric grades water quality standards.

　　2. Technology process of preparing electronics ultrapure water

　　Adopt reverse osmosis equipment and EDI equipment together to prepare electronics ultrapure water, this is the newest technology of preparing ultrapure water, it is also the environmental, economic, potential ultrapure water preparation technology.

　　The basic technology process is: raw water→multi-media filter→active carbon filter→precision filter→middle water tank→reverse osmosis equipment→EDI→ultrapure water tank→ultrapure water pump→post safeguard filter→water point
