EDR, microfibers, and PFAS: signals to watch

Electrodialysis Reversal (EDR) is getting a second life. Once overshadowed by reverse osmosis, new designs, capacitive approaches, and ceramic membranes are opening doors in brackish desalination, food and beverage, and even lithium recovery. Costs and complexity remain hurdles, but innovation is giving EDR fresh momentum . Another blind spot: microfibers. Over half a million metric tons entered the environment in 2023, with textile effluents averaging 37 mg/L. BlueTech’s new report maps th...
