Putting More Power Behind Electrodeionization – QUA FEDI Featured in WaterOnline Q&A

Reverse osmosis membranes can remove the bulk of the ionic material in water. When water must be made ultrapure, for sensitive processes like pharmaceutical or petrochemical operations, treatment operators call in the sophisticated methods.

Electrodeionization (EDI) is one such approach. Complicated and highly technical, EDI is a testament to our modern understanding of chemical processes. As if that weren’t enough, advanced membrane developer QUA has come up with an improved, energy efficient EDI method called fractional electrodeionization (FEDI). Water Online spoke with QUA’s Fred Wiesler to get an overview on electrodeionization and parse the technical details behind EDI and the company’s cost-saving innovation.
