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
7.Compact equipment, small size
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 20th 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
| a. Medical production,industrial pharmacy use |
| b. Cosmetics, Hemodialysis |
| c. Recycling water system |
| d. Chemical, electroplate industrial etc |
| e. Microelectronic, power, and biological project |
| f. Chemical Lab,semiconductor |
| g. Other electronic standard water |
Process
Raw water tank(user supply) → raw water pump → sand filter → carbon filter → softener filter → security(micro) filter → high pressure pump 1st → reverse osmosis system 1st →high pressure pump-2nd reverse osmosis system 2nd→UV lamp→EDI system→ pure water tank(user supply) - outlet
Main parts function
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.
