Process flow of ultrapure water for power plant water treatment equipment

Process flow of ultrapure water for power plant water treatment equipment

1. Ion exchange is adopted, and the process is as follows:

Raw water → raw water booster pump → multi-media filter → activated carbon filter → water softener → precision filter → cation resin filter bed → anion resin filter bed → anion cation resin mixed bed → microporous filter → water point

2. The two-stage reverse osmosis method is adopted, and the process is as follows:

Raw water → raw water booster pump → multi-media filter → activated carbon filter → water softener → precision filter → reverse osmosis → PH regulation → intermediate water tank → secondary reverse osmosis (reverse osmosis membrane surface is positively charged) → purified water tank → pure water pump → microporous filter → water consumption point

3. EDI is adopted, and its process is as follows:

Raw water → raw water booster pump → multi-media filter → activated carbon filter → water softener → precision filter → reverse osmosis machine → intermediate water tank → intermediate water pump → EDI system → microporous filter → water consumption point

Characteristics of water treatment equipment in power plant

The traditional preparation process of ultrapure water in power plants usually uses ion exchange resin to make it, but the use of ion exchange resin usually requires regular resin regeneration, which consumes both material resources and labor. The combination of reverse osmosis and ion exchange system (or EDI) is used to prepare ultrapure water. Compared with the traditional process, this process has the advantages of low operating cost (the life cycle of the ion exchanger is greatly extended), and reliable operation. Compared with the new process, it has the advantages of low cost and easy availability of consumables. The reverse osmosis technology is advanced and reliable.
