EDI plants (electrodeionization)

An EDI plant is used after RO for polishing of demineralized water to obtain low levels of conductivity and silica. EDI is an alternative to a conventional mixed-bed polisher.
Typical applications for EDI: Boiler feed water at heat and power plants, process water within the electronic industry, the pharmaceutical industry, and hospitals and laboratories.
Plant description
Flow rates up to 60 m³/h. EDI plants are either produced as standard modules or custom-made according to requirements.
Advantages
EDI is a continuous process and utilizes chemical-free regeneration. Therefore, regeneration downtime is eliminated and storage and handling of acid and lye are avoided. The plants are space-saving on account of the very compact design. The plants are of high quality, need minimum maintenance, and the reliability of operation is very high.
