Product introduction
Despite the reverse osmosis system will water the ions removal 95-98, but also cannot satisfy the requirement of industrial production, the subsequent process must use ion exchange equipment.
In recent decades, mixed bed ion exchange technology has been the standard process as a pure preparation. Due to the need of periodic regeneration and regeneration process using plenty of chemicals (ph) and pure water, so it's difficult to satisfy the alkali pure water system.
Because the traditional ion exchange has been increasingly unable to meet the need of modern industry and environmental protection, and so will membrane and resin combination EDI technology as water treatment technologies of a revolution. The regeneration of ion exchange resin, and is used to, so no more satisfied with acid in today's world environmental requirements.
Since 1986, the world since industrialization technology EDI already installed nearly 200 sets of EDI systems, especially in the pharmaceutical, semiconductors, power and surface flush industries in the development, and energetically in wastewater treatment, beverage and etc and widely used.
EDI device is used in reverse osmosis system, instead of ion exchange resin, water stability, low operating cost, operation management convenient, cover an area of an area small, etc.

EDI characteristicsEDI
E - Cell TM's technical revolution. EDI It is by the general electric company subordinate company of Canada and Japan - Cell Asahi whipping developed jointly launched in 1996, and the market. The patent technology completely satisfy without acid and alkali, low cost, replace primary mixed bed the needs of the market.
Ro + EDI device and polishing mixed bed devices, high pure water system
Process scheme (several schemes are for reference only, still have a lot of solutions to inquire)
1, level of reverse osmosis (water mixed bed + 2 - ¦¸ 15m cm).
The original water tank - - - - the activated carbon filter medium filter device - the security filter demineralized water pressure pump - - reverse osmosis host - pure water tank - pure water pump - Yin ion-exchange microporous filter mixed bed - - - - the water pump water containers uv sterilizer - the precision filter - water
2, the level of reverse osmosis + EDI systems (5 - ¦¸ 15m cm).
The original water tank - - - - the activated carbon filter medium filter device - the security filter demineralized water pressure pump - - reverse osmosis host - pure water tank - microporous filter - EDI systems - water containers - water pump - uv sterilizer - the precision filter - water
3, level of reverse osmosis + EDI systems (cm) ¦¸ 18m water.
The original water tank - - - - the activated carbon filter medium filter device - the security filter demineralized water pressure pump - 1-1 reverse osmosis host - - - level adjust PH level high-pressure pump - 2 ro pure water tank - - - degassing units microporous filter - EDI systems - the polishing of the mixed bed systems - water containers - water pump - uv sterilizer - the precision filter - water

High-purity water treatment technologies of history:
First stage: pretreatment - - > > Yin Yang bed - - - - > bed - > Yin Yang bed, bed - - > mixed bed
The second stage: pretreatment - > - 1-2 reverse osmosis - > > reverse osmosis mixed bed - > polishing mixed bed
Stage 3: > reverse osmosis preprocessing - - - - - > > EDI device polishing mixed bed

Electronic industry with ultra-pure water applications
1, semiconductor materials, devices, printed circuit board and IC products, semi-finished products with pure water,
2, the ultra pure materials and super pure reagent blending with pure water,
3, laboratory and medium run-ins with pure water,
4, automobiles, home appliance surface polishing processing,
5, optoelectronic products,
6 and medical pharmaceutical industry
7 and other high-tech subtle products
