Electrodeionization: Principle, techniques and factors influencing its performance

Ecosystems are becoming more and more polluted, hence sustainable techniques of pollution removal are needed. In the recent times, exceedingly pure water has become ideal for several industries. Modern industry needs ultra-pure water, which is highly processed water that is devoid of colloidal particles and has a conduc-tivity of less than 0.06 mu S. A very effective method for removing ionic chemicals from polluted waters emerged recently called electrodeionization. Continuous electrodeionization (CEDI) is a technique for producing high -purity water. Besides rendering purified water, the technique has got promising wastewater treatment tech-nologies - by facilitating the eradication of ionizable compounds, hazardous chemicals, radioactive pollutants, heavy metals and other potential contaminants. Innovative materials have been developed in order to advance and improve this technique, which would result in enormous ecological and financial benefit on a worldwide scale. In this review article, several factors that affect the performance of CEDI has been comprehended, with the impact of Ion-exchange resins and membranes as the focal point.

Automated summary

Ecosystems are increasingly polluted, calling for sustainable pollution removal techniques. Ultra-pure water has become essential for industries, with electrodeionization emerging as an effective method for removing ionic chemicals and producing high-purity water. This technique not only provides purified water but also holds promising potential for wastewater treatment, eliminating ionizable compounds, hazardous chemicals, radioactive pollutants, heavy metals, and other contaminants.
