1. EDI (electronic desalination system) works
High purity water is very important for many industrial and commercial projects, such as: semiconductor manufacturing and pharmaceutical industries. Previously these industrial pure water obtained by ion exchange. However, membrane and membrane system as a pre-processing process or ion exchange systems increasingly popular alternative. Desalination processes such as membrane systems (EDI) and the like can be cleanly remove minerals and can work continuously. Furthermore, the film process on the mechanical system is much simpler than the ion exchange does not require an acid, base, and wastewater and regeneration. EDI business processes is one of the film's fastest-growing process. EDI is a non-reverse electrodialysis (ED) with a special tank, the tank is filled in the flow path of the mixed bed ion exchange resin. EDI is mainly used for the total dissolved solids (TDS) of 1-20mg / L 8-17 Mohm water into pure water.
2. EDI water installations advantage
1) small footprint, omitting the mixed bed and reproducing apparatus.
2) continuous and stable water production, high water quality, and mixed bed resin approaching failure in the water will deteriorate.
3) low operating costs, renewable only consumption, not acid, saving material costs.
4) significant environmental benefits, increased security operations;
3 technical performance
EDI components operating results depend on a variety of operating conditions. EDI is to ensure the normal operation of the following minimum conditions. In order to make the system run better, the system should be designed appropriately to improve these conditions.
4. EDI water indicators
To prevent the device appears fouling, reducing its operating life, EDI for water quality have certain requirements
