Membrane technologies were studied to purify neutralising pond water for high water recovery and quality. Reverse osmosis produced good flux until it decreased rapidly at a recovery of 60%. Even 80% recovery could be obtained by forward osmosis, except when ammonium carbamate was used as a draw solution and scaling already occurred at the early stage of filtration. The flux in membrane distillation was good and stable until scaling occurred. If calcium was removed, water recovery could be increased to 93%. The order of metal rejection efficiency of the technologies was membrane distillation > reverse osmosis > forward osmosis.
