Reverse Osmosis And EDI System Plant Deionized Water Equipment For Laboratory Use
EDI Water Treatment Plant Product Introduction
What is EDI?
EDI is also known as electrodeionization, is a new type of ultra pure water producing technology which gradually developed in the 20th Century, It is a revolutionary progress in the history of pure water production technology. This technology is skillfully combined electroosmosis technology with ion exchange technology. By means of the selectivity permeation effect on anion and cation by the anion and cation exchange membrane, and exchange effect on ion by ion exchange resin. Under direct-current electric field, realize the directed migration of ions, thus completely make water salt removing, meanwhile, hydrogen ion and hydroxyl ion generated by water electrodeionization will make the ion exchange resin regeneration, so it can produce ultrapure water continuously without acid-base chemical regeneration.
Introduction of EDI:
1.EDI (Electrodeionization)is a revolutionary water treatment technology ,it is a membrane separation desalination technology that skillfully combined the electrodialysis technology and ion exchange technology together ,which is high-tech , green and environmental protection technology .
2.EDI plant has very high requests to raw water, usually we use double stage RO system production water as its raw water.
RO system:
| RO membrane purifying: (first time) high efficiency filtrating |
| RO membrane purifying: (second time ) high efficiency filtrating, (Optional) |
| UV light effective filtrating bacterium.(optional) |
| Ozone generator high efficiency filtrating bacterium (optional) |
EDI Water Treatment Plant Pretreatment:
| Sand filter used to remove the suspension, colloids. rust, impurity in water as well as some microbe |
| Carbon filter used to remove the organic matters and oxygen, bad odor, pesticide and colloids which are not removed thoroughly by sand filter |
| Water softener used to reduce the water hardness (Optional) |
| Security filter remove the impurities (diameter above 5µm). |
EDI Applications:
| 1 | the daily drinking water for community, school, hotel, factories etc |
| 2 | Desalination of water used in production techniques |
| 3 | Water used in beverage, food industry , cosmetics, pharmacy, chemical etc |
| 4 | Mobile working organizations such as ocean voyages, drilling units, field exploration etc |
| 5 | Daily drinking water used in islands, military posts, high saline and alkaline lands, sea water encroached areas, also can be applied in industry, electronic field, food etc |
