EDI (electro deionization) is a technic combined with ion exchange and electrodialysis. Under electrical field, there will be H+ & OH- produced on the surface of ion exchange membranes, which can regenerate the resins. EDI is easy to operate and has a stable effluent. Membranes in EDI need a high selective permeability and low electrical resistance. IONSEP® EDI membrane can meet the requirements well.
Lower resistance: compared with traditional heterogeneous membrane, its resistance is reduced by 30%-50%, which reduce the energy consumption.
High selective permeability brings high current efficiency and stable product water quality.
High compatibility: it can be used in most EDI membrane stacks for maintenance and membrane replacement. It is compatible with variety kinds of spacers.
EDI membrane for ultrapure water preparation.
Can customized for high temperature EDI, food grade EDI, etc.
* This membrane can be customized
according to customers’ requirements, such as high temperature resistance, etc.
