The main uses of ultra-pure water equipment in the electronic industry are: ultra-pure water equipment in the electronic industry, EDI ultra-pure water equipment, and high-purity water equipment
High purity water is used for the production of microelectronic products, ultra pure water is used for semiconductor and imaging control manufacturing, ultra pure water is used for cleaning integrated circuit board production, and production water for batteries, lithium batteries, solar cells, dry batteries, etc. This pure water equipment mainly uses reverse osmosis and EDI technology to prepare high purity water.
The main purpose of pure water equipment is:
High purity water for the production of microelectronic products,
Ultra pure water for semiconductor and imaging control manufacturing,
Ultra pure water for cleaning integrated circuit board production,
Production water for batteries, lithium batteries, solar cells, dry batteries, etc.

The processes for preparing ultrapure water in the electronic industry can be roughly divided into three types:

1. The traditional water treatment method of using ion exchange resin to prepare ultrapure water for the electronic industry is as follows:
Raw water → Multi media filter → Activated carbon filter → Precision filter → Cation bed → Anion bed → Mixed bed (double bed) → Ultra pure water tank → Ultra pure water delivery pump → UV sterilizer → Refined mixed bed → Post 0.22 filter → Water object
　　
2. The basic process flow for preparing ultra pure water for the electronic industry by combining reverse osmosis water treatment equipment and ion exchange equipment is as follows:
Raw water → Multi media filter → Activated carbon filter → Precision filter → Reverse osmosis equipment → Mixed bed (composite bed) → Ultra pure water tank → Ultra pure water transfer pump → Post 0.22 filter → Water object
　　
3. The combination of reverse osmosis equipment and electrodeionization (EDI) equipment is used to prepare ultrapure water for the electronic industry. This is a new process for producing ultrapure water, and it is also an environmentally friendly, economical, and highly promising ultrapure water preparation process. The basic process flow is as follows:
Raw water → Multi media filter → Activated carbon filter → Precision filter → Reverse osmosis equipment → Pure water tank → EDI booster pump → Electrodeionization (EDI) → Ultra pure water tank → Ultra pure water transfer pump → Rear 0.22 filter → Water object

Raw water → Multi media filter → Activated carbon filter → Precision filter → Secondary reverse osmosis → Intermediate water tank → EDI booster pump → EDI device → Ultra pure water tank → Ultra pure water transfer pump → UV sterilizer → Refined mixed bed → 0.22 or 0.5 μ M precision filter → water object

3、 Characteristics of Ultra Pure Water Equipment in the Electronic Industry
The ultra-pure water equipment in the electronic industry usually consists of a pre-treatment system composed of multi-media filters, activated carbon filters, sodium ion softeners, precision filters, etc., a RO reverse osmosis host system, an ion exchange mixed bed (EDI electric desalination system) system, and other main equipment systems. The raw water tank, intermediate water tank, RO pure water tank, and ultra pure water tank are all equipped with liquid level control systems, pressure protection devices, online water quality detection and control instruments, and PLC programmable controllers are used for electrical control, truly achieving unmanned operation. At the same time, the recommended and customer requirements are unified in process material selection, making this equipment have high cost-effectiveness and equipment reliability compared to other similar products.
