EDI Module

Electrodeionization (EDI) is a combined technology of Electrodialysis and Ion Exchange, it is continuous process of removing ionized and ionizable species from feedwater especially RO permeate water, producing high quality ultra pure water with consistent performance, it can be designed for modular system design with wide range of flow options, DelPure EDI modules offer flow capacity from 100LPH to 8000 LPH. EDI modules are widely used in water treatment applications such as power plant, semiconductor, pharmaceutical and fine chemical etc.

Direct replacement for EDI module / EDI stack from international vendors is also available, welcome to contact Delta sales if any request.
