The production of ultrapure water uses a combination of membrane separation and ion exchange processes. EDI is a process that combines semi-permeable membrane technology with ion exchange to provide a highly efficient demineralisation process. Unlike traditional ion exchange systems, an EDI system does not require chemicals.
Electro Deionisation (EDI) is a technique for producing demineralised (demi water) / Ultra Pure Water (UPW) and consists of a combination of membrane filtration and an ion exchange unit. The EDI process produces industrial process water of very high purity, using less than 95% of the chemicals used in conventional ion exchange processes. With the EDI system, membranes and electricity replace the large amounts of litres of acid and base chemicals that the old processes required on a daily basis.
As an alternative to traditional ion exchange processes, EDI brings advances in both the energy and operating costs of water treatment and purification technologies. Environmental benefits are also realised by avoiding and removing acidic and caustic chemicals brought into the field by eliminating the regular regeneration requirements for ion exchange resins.
Grünbeck EDI systems have many important features and benefits, including:
EDI brengt ook nadelen met zich mee, namelijk:
EDI systems offer a wide range of benefits. These include high water efficiency and very pure water without the use of chemicals.
