　　1.An overview of Ultrapure Water in the Electronics Industry

　　Semiconductors, integrated circuit chips and packaging, liquid crystal displays, high-precision circuit boards, optoelectronic devices, various electronic devices, microelectronics industry, large-scale and very large-scale integrated circuits require a large amount of pure water, high-purity water and ultra-pure water to clean semi-finished and finished products. The higher the integration degree of integrated circuits, the narrower the line width, and the higher the requirements for water quality. At present, the Ministry of Electronics Industry of our country classifies electronic-grade water quality technology into five industry grades, namely18MΩ.cm,15MΩ.cm,10MΩ.cm,2MΩ.cm,0.5MΩ.cmTo distinguish different water qualities.

　　2.The process flow for preparing ultrapure water for the electronics industry

　　The processes for preparing ultrapure water in the electronics industry can be roughly divided into the following3Seed

　　1The traditional water treatment method for preparing ultra-pure water for the electronics industry using ion exchange resins has the following basic process flow: raw water→Multi-media filter→Activated carbon filter→Precision filter→Middle water tank→Yang bed→"Yin bed"→Mixed bed (double bed→Ultra-pure water tank→Ultra-pure water pump→Rear security filter→Water usage point

　　2The basic process flow for preparing ultra-pure water for the electronics industry by combining reverse osmosis water treatment equipment with ion exchange equipment is as follows: raw water→Multi-media filter→Activated carbon filter→Precision filter→Middle water tank→Reverse osmosis equipment→Mixed bed (double bed→Ultra-pure water tank→Ultra-pure water pump→Rear security filter→Water usage point

　　3Adopt reverse osmosis equipment and electro-deionizationEDIThe method of preparing ultra-pure water for the electronics industry by combining equipment is a new process for producing ultra-pure water and also an environmentally friendly, economical and highly potential ultra-pure water preparation process. Its basic process flow is: raw water→Multi-media filter→Activated carbon filter→Precision filter→Middle water tank→Reverse osmosis equipment→Electro-deionizationEDI)→Ultra-pure water tank→Ultra-pure water pump→Rear security filter→Water usage point

　　3.Features of ultra-pure water equipment for the electronics industry

　　Ultra-pure water equipment for the electronics industry is typically composed of a pretreatment system made up of multi-media filters, activated carbon filters, sodium ion softeners, precision filters, etc.ROReverse osmosis main unit system, ion exchange mixed bedEDIThe main equipment system is composed of the electro-deionization system, etc. Raw water tank, intermediate water tankROBoth the pure water tank and the ultrapure water tank are equipped with liquid level control systems. Both the high and low pressure water pumps are provided with high and low pressure protection devices, online water quality detection and control instruments, and electrical systems are adoptedPLCThe programmable controller truly achieves unattended operation.
