GE membrane based Electrodialysis Reversal (EDR) systems offer attractive characteristics such as higher water recovery, increased resistance to scaling and fouling, and membrane stability in oxidative environments. Research activity at GE Water & Process Technologies, have extended these capabilities to include high pH environments, through the development of a new high performance anion exchange membrane that tolerates aggressive caustic cleaning conditions. This will enable the expanded application of EDR systems in markets that are limited by the currently practiced cleaning-in-place procedures.
