Electrodeionization EDI Systems

Product Description

Electrodeionization (EDI) Systems remove ions from aqueous streams, typically in conjunction with reverse osmosis (RO) and other purification devices. Our high-quality modules continually produce ultra-pure water up to 18.2MΩ/cm. EDI may be run continuously or intermittently. Electrodeionization is a green solution for deionizing water. With no expensive chemical upkeep and virtually no down-time, electrodeionization units are the future in deionization. Call us today for more information how you can revolutionize the way you make ultrapure water.

Electrodeionization Equipment Advantage:

The need to satisfy the increasing demand for high purity water can be achieved using Electro-Deionization (EDI) equipment. The EDI process replaces conventional DI mixed resin beds to produce deionized water.

Unlike DI resin, EDI does not require shutdowns for replacing resin beds or for resin regeneration using chemicals. As a result EDI minimizes water quality upsets and operating costs.

EDI has become the solution of choice, lower operating expenses and fewer maintenance requirements makes EDI the cost effective choice over mixed bed or dual-bed polishing.

Pure Aqua supplies a full line of standard and fully customizable Electro-Deionization systems, all of which are engineered using advanced 3D computer modeling and process design software for accurate and customized solutions.

Pure Aqua| Reverse Osmosis System and EDI AL, USA 7,500 GPD 02:01

Pure Aqua designed and manufactured reverse osmosis followed by an Electro-Deionization (EDI) systems to provide purified water for a major company in Alabama, USA. The 7,500 GPD systems were designed to treat municipal tap water with a TDS of 250 ppm. The product water from the RO passes through the Electro-Deionization (EDI) to achieve resistivity of 10 to 18 megohms.
