Capacitive Deionization for the Removal of Total Dissolved Solids (TDS)


Environment Water and Wastewater

Capacitive Deionisation System


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


Water containing arsenic, nitrate, fluoride, perchlorate, ammonia, sulfate, metals or other ionic compounds can be treated using capacitive deionization. In addition: Reduce TDS High removal efficiencies High water recovery No chemical additives Low maintenance Low energy consumption

Manufacturer's Description

Capacitive deionization is a simple electrochemical process that effectively lowers the concentration of total dissolved solids in water.

ESD is a cost effective system that utilizes the principles of capacitance deionization based on the company’s patent-pending IP.

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

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.
