Electrodeionization EDI Systems https://aquacomponents.sa/product/electrodeionization-edi-systems/ Thu, 13 Mar 2025 12:35:37 +0000 https://aquacomponents.sa/product/electrodeionization-edi-systems/ 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 on 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.

EDI modules are on average miniature in size and weight in terms of per unit flow in the market. Unlike DI resin, EDI water purification systems do not require shutdowns for replacing resin beds or for resin regeneration using chemicals. As a result the 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 IX or dual-bed polishing. Fewer maintenance demands also means less facility needs and managerial supervision, which saves additional labor costs.

These systems also require minimal energy to provide steady, and persistent ultra pure water. EDI water purification systems utilize compact footprints, which benefits water treatment plants in using less available space to provide the same amount of water.

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

Here at Pure Aqua, Inc., we engineer and build all of our water treatment systems in-house.

Our turn-key water treatment systems are all pre-engineered using the latest CAD technology available.

This enables our teams to build and deliver treatment systems to our customers with quick turnaround times.

Many of our customers require custom engineered systems. These are typically built around similar core systems and thus allowing for improved turnaround times, even for one-off designs.
