Double Stage RO System EDI Electric Desalination 500lph for Hemodialysis

Double Stage Ro System and EDI Electric Desalination 500LPH For Hemodialysis

Advantages of EDI Technology

1.Best stability of water quality

2.Constantly produce ultrapure water as per user requirements

3.Modular production, can achieve automatic control

4.No need acid and alkali regeneration, no pollution emissions

5.No need stop because of regeneration

6.No need regeneration equipment and chemical storage

8.Low operation and maintenance cost

9.Simple operation and low labor strength

EDI system

EDI, also known as electric desalination. It is a new ultra pure water technology which gradually developed in the 20 ^th  century. EDI equipment combined electro dialysis technology and ion exchange technology. It is using the selectivity penetrate function of anion and cation membrane and exchange function of ion exchange resin, under direct current electric field to make ion directed migration. Finally to make deep desalination of water. In the same time, hydrogen ion and hydroxide ion which produced when water ionize will regenerate ion exchange resin. So if use EDI equipment, no need acid and alkali chemical to do any regeneration, and it can produce ultra pure water continuously.

Application 

1. Raw water pump-- provide the pressure to quartz sand filter/active carbon filter/softener.
2. Multi-medium filter--get rid of turbidity, suspended matter, organic matter, colloid, etc.
3. Active Carbon filter--Remove the color, smell, free chloride, organic matter, harmful matter, etc.
4. Softener--exchange "ions" of calcium and magnesium with the most common and easiest method.
5. Security filter--prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um,
6. High pressure pump--Provide the high pressure to RO membrane.
7. RO system-- main part of the plant. The RO membrane's desalting rate can reach 99%, removing over 99% ions.
