Principle and efficiency of direct reverse osmosis<\/h2>\n\n

Direct reverse osmosis treatment is a process for filtering and purifying landfill leachates.\nLeachates are effluents charged with multiple pollutants (metals, organic pollution, nitrogen, salts, etc.) resulting from the burial of waste. <\/p>\n\n

With ever-increasing volumes of waste being landfilled around the world, leachate management is a major challenge for the preservation of the environment.\nIt is therefore imperative to treat these effluents to reduce their harmful impact on the environment. <\/p>\n\n

This technique offers an effective solution to this challenge.\nIt is based on a semi-permeable membrane leachate treatment process in which the operating pressure is higher than the osmotic pressure.\nPollutants, including salinity, are retained by the membrane, while the purified water, called permeate, is recovered for reclamation or returned to the natural environment. <\/p>\n\n

Benefits and flexibility of direct reverse osmosis<\/h2>\n\n

Pre-filtration is provided upstream of the membranes by processes adapted to each type of leachate: sand filters, cartridge filters, or even physicochemical treatment…\nDepending on the discharge standards to be met, several membrane stages can be used.\nThis type of osmosis stands out for its rapid implementation and broad treatment spectrum. <\/p>\n\n

The process is highly modular and can therefore be easily adapted to variations in leachate composition, by adding a stage, a pass or a pre-treatment.\nThe main leachate parameters, such as temperature, pH and conductivity, are continuously monitored by the PLC, which adapts pressures and flows in real time.\nDischarge is automatically stopped in the event of any parameter drift.\nIn an emergency, the system can be transported, installed and up and running in less than a week. <\/p>\n\n

The advantages of reverse osmosis leachate treatment are numerous, including : <\/p>\n\n
