High salinity in wastewater effluent can be an obstacle to reclamation and potable reuse.
Salinity removal typically relies on advanced treatment with reverse osmosis, but that means dealing with a brine waste stream. It’s especially challenging for communities where ocean discharge is inaccessible, or deep-well injection is restricted, or the loss of water to the brine solution is unacceptable. Meanwhile, carbon-based advanced treatment does not produce brine waste, but cannot address elevated influent salinity.Now Carollo Engineers is bench-scale and pilot testing Ion-Exchange-Based Advanced Treatment (XBAT), an alternative technology that enables utilities to address not only salinity but also organics and TOC,
