Abstract

There is disclosed a method for recovering pure water from aqueous contaminated streams containing high levels of salts and suspended solids, such as landfill leachate, comprising (a) contacting the aqueous stream with one side of a semipermeable membrane, the other side of which is in contact with an aqueous brine solution at a higher osmotic pressure, wherein the aqueous stream is provided at a pressure less than 350 kPa, whereby pure water passes through the membrane from the aqueous stream into the aqueous brine solution, and (b) recovering pure water from the aqueous brine solution by a reclamation procedure selected from the group consisting of (1) a reverse osmosis (RO) process, (2) and electrodialysis process, (3) an evaporation process, and (4) a combination thereof, thereby reconcentrating the aqueous brine solution.
