The main core of EDI pure water equipment lies in the purification function of the EDI module. Through the water treatment technology of the EDI module, the pure water purification can reach about 16 megaohms. If the industrial required pure water quality reaches 18 megaohms, it can only be achieved by polishing the pure water treated by the EDI module with resin.

 

The principle of EDI water treatment process: The membrane block EDI units of pure water equipment are separated by grids, and there is a certain number of membrane block EDI units. The separated EDI units will form a fresh water chamber and a concentrated water chamber. Under the push of direct current, the anode and cathode electrodes at both ends will cause the cations in the water flow of the fresh water chamber to migrate to the concentrated water chamber through the cation exchange membrane. When the electric field in the fresh water chamber is removed, the water molecules in the inlet water will be decomposed into ion exchange resin interfaces H and OH -, and the cation exchange resin will be continuously regenerated in the fresh water chamber.

 

In addition to EDI module water treatment and purification technology, there are also processes such as reverse osmosis membrane filtration, filter filtration, mixed bed process, deionized water technology, etc. For detailed process information, please visit Shanghai Yishuo Water Treatment Equipment Manufacturer.

 

The advantage of the equipment is that it can continuously produce water and maintain stable water quality. No water treatment agents need to be added during the production process, so there will be no secondary pollution of water. The water production rate of pure water is as high as about 95%. The equipment will not stop during the entire operation period due to the need to replace acid-base regeneration factors. The entire process is simple and convenient to operate.
