Overview of Ultra Pure Water Supply System for Power Boiler
Coal fired power plants are an important component of China's power industry. The use of water in the power industry is multifaceted, mainly including boiler makeup water, cooling water, and miscellaneous water for domestic firefighting. The most stringent requirement for water quality is boiler feedwater. Nowadays, thermal power plants are developing towards large capacity and high parameters, and the water quality of boiler feedwater is also increasing. The requirements for boiler feedwater water quality are very strict. Therefore, in addition to conventional water treatment methods such as coagulation, sedimentation, and filtration, pure water preparation technologies such as ion exchange, reverse osmosis, electrodialysis, softening, and desalination are also needed.

The process of preparing super water in the power industry
The process of using EDI is as follows:
Raw water → Raw water booster pump → Multi medium filter → Activated carbon filter → Softener → Precision filter → Primary reverse osmosis machine → Intermediate water tank → Intermediate water pump → EDI system → Microporous filter → Water point
3. Characteristics of ultra pure water equipment for power boiler feedwater system
The traditional preparation process of ultrapure water usually uses ion exchange resin for production, but the use of ion exchange resin usually requires frequent resin regeneration, which consumes both material resources and labor. After years of practice and combined with new membrane separation technology, our company often uses a combination of reverse osmosis and ion exchange system (or EDI) to prepare ultrapure water. Compared with traditional processes, this process has the advantage of low operating costs (the regeneration cycle of ion exchangers is greatly extended) and reliable operation. Compared with new processes, it has the advantages of low cost and easy availability of consumables. The reverse osmosis process technology is reliable
