In the drinking water sector, anion exchange technologies are increasingly used for color and disinfection by-products removal, which targets low molecular weight natural organic matter, particularly humic substances (HS). After treatment, resins are regenerated to 99.9% recovery with NaCl resulting in a saline waste stream, referred to as brine. The resulting brine contains left-over NaCl, as well as desorbed inorganic and organic anions (SO42- , HCO3-, HS, etc.) from raw water. Disposal of this brine is a problem, especially with regulations becoming increasingly strict. Fortunately, compounds in the brine can be reclaimed if properly separated: NaCl for direct reuse in the regeneration process; and HS as bio-stimulants for crop growth. Previous investigations highlighted the efficiency of using electrodialysis technology to achieve this separation of 1) NaCl with mono-selective membranes and 2) divalent ions from HS with non-selective membranes. However, little was known about the effect of high organic loads from the brine on operations causing fouling or spacer clogging.

520 $a In the drinking water sector, anion exchange technologies are increasingly used for color and disinfection by-products removal, which targets low molecular weight natural organic matter, particularly humic substances (HS). After treatment, resins are regenerated to 99.9% recovery with NaCl resulting in a saline waste stream, referred to as brine. The resulting brine contains left-over NaCl, as well as desorbed inorganic and organic anions (SO42- , HCO3-, HS, etc.) from raw water.

Previous investigations highlighted the efficiency of using electrodialysis technology to achieve this separation of 1) NaCl with mono-selective membranes and 2) divalent ions from HS with non-selective membranes. However, little was known about the effect of high organic loads from the brine on operations causing fouling or spacer clogging.
520 $a The purpose of this research was to evaluate the long-term feasibility of electrodialysis technology for treatment of an anion exchange brine including NaCl and HS recovery. Electrodialysis treatment with mono-selective membranes was evaluated on pilot scale over a six-month period while recording operational data and quality of the by-products. Additional experiments were also conducted to further understand the overall fouling phenomena and lab-scale simulation of spacer clogging. Results demonstrate that ED treatment with mono- and non-selective membranes is an innovative process, effective at targeting the recovery of resources from concentrated waste streams.
