Introduction of Electrodeionization 

Electrodeionization, also known as EDI, is an electrolytic process that removes ions from water, is a continuous and chemical-free process of removing ionized and ionizable species from the feed water using DC power.

EDI is typically used to polish reverse osmosis (RO) permeate and to replace conventional mixed bed ion exchange, which eliminates the need to store and handle hazardous chemicals used for resin regeneration and associated waste neutralization requirements.
