Treatment of landfill leachate using a solar destillar
AbstractThe subject of this research was to build, develop, evaluate and optimize a system of natural evaporation of leachate, to reduce the organic loads. Physical and chemical microbiological parameters were monitored during the experiment to evaluate the system performance. The solar radiation and rainfall influence on the evaporator was investigated. The results showed 100% reduction of the turbidity, color and total solids. The values of BOD, COD, thermotolerants and total coliforms in the treated effluent had concentrations that meet the Brazilian Federal Environmental Council (CONAMA) standards. Based on the results, it was concluded that the natural solar system was adequate for small landfills.
