A pilot brine concentrator treated Stage 3 reject effluent from a mine water reclamation plant, raising total dissolved solids from 24 g/L to 154 g/L at 88 per cent water recovery. The condensate met the national potable water specification. A separate run concentrated brine from 76 g/L to 145 g/L, solid salts were precipitated, and no scaling or fouling was seen.
