Usually used in combination with reverse osmosis (RO) and other purification techniques, electrodeionization (EDI) systems extract ions from aqueous streams. Up to 18.2 MΩ/cm of ultra-pure water is continuously produced by our premium modules. EDI might run sporadically or continuously. One environmentally friendly method of deionizing water is electroionization. Electrodeionization units are the deionization of the future since they require no costly chemical maintenance and have almost no downtime. For more information on how to transform the way you produce ultrapure water, give us a call right now.

Control unit that can be monitored.
There is no recirculation of concentrate in simple systems.

Advantages of EDI:
Reliable water quality.

Continuous functioning.
No chemicals for regeneration.
Not a single dangerous waste.
Lessens the need for facilities.
Technology that is simpler—no recirculation of concentrate.
Easy to use (no need to replace the batch DI resin).
A modular system is more adaptable and simple to grow.
One big stack is riskier than several modules.
Adjust the product's water quality by adjusting the amps.
Compact modules reduce the size of the system.
No leaks—the module design is verified.
Reduced and safer voltages.

Benefits of Electrodeionization Equipment:

Equipment for electro-deionization (EDI) can be used to meet the growing demand for highly pure water. In order to provide deionized water, the EDI method takes the place of traditional DI mixed resin beds.
In terms of market flow per unit, EDI modules are often very small in both size and weight. In contrast to DI resin, EDI water purification systems don't need to be stopped down in order to change resin beds or perform chemical resin regeneration. Consequently, the EDI reduces operating expenses and disturbances in water quality.
Since EDI requires less maintenance and has lower operating costs than mixed-bed IX or dual-bed polishing, it has emerged as the preferred alternative. Additional labor costs are saved since fewer maintenance requirements also translate into fewer facility requirements and managerial oversight.
Additionally, these systems use very little energy to deliver consistent, long-lasting, ultra-pure water. Compact footprints are used by EDI water purification systems, which helps water treatment facilities use less area to deliver the same volume of water.
Advanced 3D computer modeling and process design software are used in the engineering of Pure Aqua's whole range of standard and fully customizable EDI water purification systems to ensure precise and personalized results.
