Electrodeionization Plants

Lenntech can design, build and commission tailor-made and turnkey EDI plants.

Our EDI (electro deionization) plants are built with conventional plate-and-frame arrangement EDI modules capable of treating several flows, in order to produce demi or ultra-pure water from Reverse osmosis permeate or Ion exchange demi-plants.
