Recovery of potassium from landfill leachate concentrates using a combination of cation-exchange membrane electrolysis and magnesium potassium phosphate crystallization

摘要：

1.Introduction Nanofiltration (NF) and reverse osmosis (RO) filtration system are widely used in landfill sites as polishing step for advanced treatment of landfill leachates.The membrane systems always generate large amount of concentrates containing high level of refractory organic compounds,potassium,chloride and other inorganics,which hardly be treated via conventional biological process.Thus,a proper disposal of these concentrates from or RO systems is critically important.
