Overview

Electrodeionization (EDI) in desalination

Protection of sensitive processes

EDI or the electro-deionisation process uses a combination of an ion exchanger resin with membrane technology and electric electrodes. It does not require any regeneration chemicals and is typically used for final treatment, or polishing, after the first stages of desalination.

KROHNE supplies a full range of OPTIFLUX electromagnetic flowmeters, OPTISONIC UFM for low conductivity permeate flows and other instruments required for control of the entire process.
