Description
To date, over 40 electrodialysis reversal (EDR) systems are treating surface and wastewaters around the world. Five surface water and three wastewater facilities have production capacities in excess of 1 mgd. Pretreatments range from simple contact filtration with chlorination to clarification and filtration with lime softening. Not one of these plants has had to replace cation or acrylic anion membranes as a result of colloidal bacterial, organic, metals or polymer fouling. In addition, no plant has required membrane replacements due to attack by oxidizing disinfectants. While a few plants have required disassembly and washing to remove deposits when serious pretreatment problems have occurred, many of these plants have never been cleaned in this manner. These are the reasons EDR has a reputation as a membrane process that works on surface and wastewaters.
