Electro-Deionisation (EDI) is an advanced water purification technology that combines ion-exchange resins and electricity to remove ionised and ionisable impurities from water. It is a chemical-free and continuous process used primarily for producing high-purity water in industries like pharmaceuticals, power generation, electronics, and laboratories.
EDI is a continuous electro-chemical process of water purification where ion specific membranes, mixed bed resin, and a DC voltage across them, replace the standard acid- caustic chemical regeneration process.
