AVALIAÇÃO DE MEMBRANAS DE OSMOSE INVERSA NO TRATAMENTO DE CHORUME DO CENTRO DE TRATAMENTO DE RESÍDUOS SÓLIDOS DO MUNICÍPIO DE CAMPOS DOS GOYTACAZES - RJ

Abstract

The irregular release of slurry into the environment causes major problems for human health and the ecosystem. Several treatment technologies have been studied and applied in the treatment of this leachate, such as the reverse osmosis membrane separation system, which has shown important results in the removal of ions and low-molecular-mass organic substances, meeting the quality standards of established by the environmental legislation in force in Brazil. Therefore, the present study sought to evaluate the efficiency of this technology at the Solid Waste Treatment Center in the municipality of Campos dos Goytacazes (CTR-CAMPOS), located in the state of Rio de Janeiro, through the analysis of the quality parameters of raw and treated leachate. produced in the sanitary landfill and monitored monthly for 5 months. Copper presented a rejection of 94% to 96% in the months of July to October, in the month of November the limit of quantification of the method was reached both in the raw leachate and in the treated leachate. The present study demonstrates that the treatment of slurry by reverse osmosis membranes at the CTR-CAMPOS showed a considerable rejection of toxic chemical substances, respecting the values required by CONAMA Resolution No. irrigation of the landfill and release into water bodies without causing major negative impacts to the environment.
