Introduction to the process flow for manufacturing ultra-pure water equipment for the electronics industry

Thread Content

　　1. The traditional water treatment method for producing ultra-pure water for the electronics industry uses ion exchange resins. The basic process flow is as follows: raw water → multi-media filter → activated carbon filter → precision filter → intermediate water tank → cation exchange resin bed → anion exchange resin bed → mixed-bed resin bed → ultra-pure water tank → ultra-pure water pump → post-filter → point of use.

2. Another method for producing ultra-pure water for the electronics industry involves combining reverse osmosis water treatment equipment with ion exchange equipment. The basic process flow is as follows: raw water → multi-media filter → activated carbon filter → precision filter → intermediate water tank → reverse osmosis equipment → mixed-bed resin bed → ultra-pure water tank → ultra-pure water pump → post-filter → point of use.

3. A third method involves using reverse osmosis equipment in combination with electro-deionization (EDI) equipment to produce ultra-pure water. This is a new process for generating ultra-pure water, and it is also an environmentally friendly, cost-effective method with great potential for further development. The basic process flow is as follows: raw water → multi-media filter → activated carbon filter → precision filter → intermediate water tank → reverse osmosis equipment → electro-deionization (EDI) equipment → ultra-pure water tank → ultra-pure water pump → post-filter → point of use
