EDI belongs to the precision processing system,it replacing the traditional mixed ion exchange water treatment process equipment,the operation of EDI is more easier than complex mixed bed operation,it suitable for continuous operation,the EDI system for the electrical conductivity of water requirements of less than 20 mu s/cm.general front is two level of RO membrane device,the EDI system produced water resistivity greater than 15M over.CM.
The advantages of EDI:
EDI dose not needs chemical regeneration,save the acid and alkali
EDI can be run continuously To rovide a stable quality;
Small occupation of land Low operation cost;
The quality of EDI water produce
High quality of water production of high quality,it more than
Reduction of SiO2 and TOC in primary mixed bed
The recovery rate as high as 90-95%.
