Recirculation as the form of destination of the Concentrate originated from the Treatment of leachate in landfills by Membrane Processes

The different methodologies of leachate treatment are widely debated in the literature, promoting a great discussion among scientific and academic community on most efficient propitious methods. Membrane processes, especially Reverse Osmosis (RO), stand out as best solution. RO has pollutant removal rates higher than 99%, with operational cost complexity competitive other technologies. Its main disadvantage is concentrated residue generated process that covers about 30% volume entering system. recirculation body landfill arises an alternative low destination cost. effectiveness directly related to method along geological, climatological, technical conditions landfills. Although already widespread, or concentrate requires greater technological assertion. Further research needed methods its medium long-term effects leachate, settlement landfills after care period. It important make comparative analysis similar characteristics, one another without concentrate. Alternatives treat also interest whether they economically viable real scale.
