Water filter system using EDI technology

Water filter system using EDI technology

SPECIFICATIONS WATER FILTER SYSTEM EDI :
EDI ( Electro - de - ionization ) is a technique to water treatment technique combining ion exchange , membrane ion exchange technology , engineering electromotive force ( electrical engineering dialysis ) . This technique is beneficial to use ion exchange desalination overcome the polarization of electro dialysis for desalination is not radical , and power advantage dialysis occurs electrolysis of water into hydrogen ions and OH , do exchange resins rehabilitation consumed through chemical processing to recover , a new technique was widely used from the last 80 years . After more than two decades of development , EDI technology has dominated the market ultrapure water treatment in North America and Europe and America .
EDI includes ion exchange membrane negative / positive , ion exchange resins , DC source . In the negative ion exchange membranes allow only negative ions through osmosis , ion exchange membranes allow only positive ions through osmosis . Exchange resins in ion exchange membrane between negative / positive form single processor , make fresh water room . The compartment is separated by a single character mesh , creating room dark water . At the negative electrode / positive power a two -dimensional structure of the electric field single . Water passing through the water room light , negative ions / positive in the water under the influence of an electric field through the ion exchange membrane negative / positive reduction eliminated , go into the room dark water . Seeds ion exchange membrane exchange between the speed of the ions eliminated . At the same time the water molecules under the influence of a magnetic field formed pH ion , hydroxyl ion , the ion conducting recovery ion exchange resins . EDI distributed water levels into 3 independent water : water ( 90 % -95 % ) ) , dense water ( 5 % -10 % ) can be circulate processing , waste water ( 1 % )
EDI water treatment system of the planet , usually used in combination with reverse osmosis treatment system made ​​up of water , equipment replacement ion exchange mixture of traditional water treatment technologies . In EDI technology , water resistivity requires 0025 - 0.5MΩ · cm , reverse osmosis equipment can fully meet the requirements . Ultrapure water through EDI technology has resistance up to 18MΩ · cm or more .
Characteristics EDI water purification equipment ;
EDI technology does not require chemicals to restore the function of ion exchange resins in water treatment technology tradition . Its main characteristics are as follows :
    • Continuous operation , stable water quality less known about the water quality .
    • No need to use chemicals in the water purification process .
    • Not for circulation to restore the machine to stop .
    • Saving water recovery and wastewater treatment equipment
   • production of high efficiency ( 95% ) · No equipment storage , dilute acids
• Occupy less space *
* Use safety , workers avoid exposure to acid and other toxic substances .
   • Reduce operating costs and maintenance using EDI technology in the industry .
   • a single device , can be flexibly combined with installation of various water
 • Simple installation , fast and easy system maintenance , low cost
 • Investment largest original equipment other than equipment
Compare EDI devices and equipment other mixed ion exchange
EDI equipment and devices are mixed ion exchange water treatment equipment is fine in the water treatment system , let us compare the quality of water , the initial capital investment , operating costs of them to see the Vietnam 's best equipment EDI applications in wastewater treatment and other water filter .
( 1 ) Water quality when using EDI water treatment technology ;
EDI equipment should have continuity Water quality stability , resistance to den18.25MΩ · cm ultrapure water standards . Ion exchange equipment discontinuity mixture , after restoring the water quality good but before restoring the poor water quality .
( 2 ) the initial capital investment for EDI water purification systems ;
Compared with ion exchange equipment , the equipment mix EDI requires an investment of about 20 % larger , but ion exchange equipment necessary mixture was kept acid , more acid and wastewater treatment equipment . Maintenance workers , rather exchange resins ( about 2 people ) is estimated at 10 % . Along with the improvement of technical and production batches , the initial capital investment and fewer EDI equipment and this equipment factory footprint .
( 3 ) Operating Expenses
Operating costs include the cost of electricity : EDI takes 0.5kwh / t water , ion exchange equipment mix lost 0.35kwh / t water , drug solution ( device only mixed ion exchange loss ) , cost depreciation ( equal ) . In addition to the operating costs of the equipment mixed ion exchange equipment EDI higher ( purchase cost equipment stored, mixed acid solution buy ... ) . In short, during the operation of the water production cost is about 48,600 devices EDI VND/m3 water , operation cost and equipment is a mixture of ion exchange VND/m3 86,400 . Such devices may EDI in 1-2 years to recover investment .
