Electro-Static Deionization (ESD) for the Removal of Total Dissolved Solids (TDS) 

Electro-static deionization is a proven electrochemical process that effectively lowers the concentration of total dissolved solids (TDS) in water.

ESD is a cost effective system that utilizes the principles of capacitive deionization based on the company’s patented technology.

Water containing arsenic, nitrate, fluoride, perchlorate, ammonia, sulfate, metals or other ionic compounds can be treated using capacitive deionization.

ESD is offered in two designs; one removes all charged dissolved solids, while the other preferentially removes monovalent ions such as nitrate and fluoride.

ESD systems can also be used to concentrate dilute solutions, for example, the recovery of valuable metals or nutrients from waste streams.

Independent testing of the ESD system has demonstrated its capabilities. The tests targeted 85% removal of specific compounds added separately to tap water. The target was achieved in all cases.
