Selectively trapping toxic or useful ions could reduce toxicity of brine waste and offset costs
A new type of purification membrane that could simultaneously produce fresh water for drinking or agriculture and absorb specific contaminants from the brine left behind has been demonstrated by researchers in the US. The team believes the technology could potentially help to extract potable water from difficult sources without complex, multi-step processes, as well as extracting valuable minerals from water.
