EDI does not consume salt and recycle the concentrate in operation, which save much expense and makes the system much simpler.
Counter current
Concentrate and electrolyte stream are flowing into EDI in opposite directions to feed water can avoid fouling effectively. Then it broadens the feed water limit adequately.
Low energy consumption
EDI filled with resin reduces the EDI module resistivity significantly,which rdduces the energy consumption largely.
High quality materials and components
High quality ion-exchange membrane and appropriate degree of resin compaction make the EDI work effictively.
Simple arrangement,installation,operation and electricity safety
Easier to array modules side-by-side on a skid,The power connector of EDI is waterproof.
Electric Specification
1. The requirements of DC power used in EDI systems, Including ripple and current control,are quite unique,to meet these requirements.
2. Digital display
3. High frequency and high efficiency,high PF(Power factor), high reliabillty.
4. Low ripple,low noise and small foot print.
5. Individually controlled
Applications
1. Advanced boiler feed water desalination
2. Purified water for petrochemical and chemical purposes
3. Purified water for biochemical and pharmaceutical purposes
4. Purified water for electronic industry
5. Purified water for laboratories
