1. ENHANCED REMOVAL OF PERSISTENT CONTAMINANTS AND TOXICITY REDUCTION THROUGH THE APPLICATION OF A TRIPLE-STAGE FENTON PROCESS TO SANITARY LANDFILL LEACHATES FROM YUCATAN, MEXICO
Sanitary landfill leachate (SLL) is a mixture of highly toxic and recalcitrant pollutants that threatens the water quality of the Yucatán Peninsula karst aquifer, one of the most extensive aquifers on the planet. To reduce the adverse environmental impacts of this wastewater, a triple-stage Fenton process (FP) was applied in an old SLL. Removal efficiencies

2. CO-TREATMENT OF LEACHATE AND DOMESTIC SEWAGE AND ITS INFLUENCE ON NITROGEN REMOVAL
Abstract This research investigated the performance of two pilot-scale treatment plants: an activated sludge and a hybrid model type IFAS (Integrated Fixed-Film Activated Sludge), combining sanitary landfill leachate with domestic sewage treatment with the objective of removing organic substances. In order to assess the possible impacts on the treatment, thr

3. Post-treatment of landfill leachate using rice husk ash as adsorbent medium
Resumo O aterro sanitário é o método mais geral de disposição de resíduos sólidos urbanos. Porém, no processo de degradação da matéria orgânica é produzido um líquido de coloração escura de alto potencial poluente sendo necessário tratamento adequado antes de seu lançamento nos corpos de água. Diversas tecnologias podem ser utilizadas no t

4. Strategy for Treating a Landfill Leachate by Integration of Physico-Chemical and Photo-Fenton Processes
This study reports a protocol for the treatment of a sanitary landfill leachate through integration between a stage of coagulation-flocculation, a step of filtration of the resulting suspension, and application of the photo-Fenton process using a ferrioxalate complex and solar irradiation. The best results for turbidity removal by coagulation-flocculation we

5. Treatment of Sanitary Landfill Leachate by Photo-Fenton Process: Effect of the Matrix Composition
In this study it was evaluated the role of the composition of sanitary landfill leachate on the removal of dissolved organic carbon (DOC) by photo-Fenton process. The composition of the matrix (high turbidity and color, as well as presence of inorganic ions sulfate and chloride) does not reduce the efficiency of DOC removal by photo-Fenton reactions, but inf

6. EFFECT OF SULFATE LOADING RATE AND ORGANIC LOADING RATE ON ANAEROBIC BAFFLED REACTORS USED FOR TREATMENT OF SANITARY LANDFILL LEACHATES
AbstractThis study investigated the effect of organic loading rate (OLR) and sulfate loading rate (SLR) on landfill leachate treatment by a lab-scale anaerobic baffled reactor (ABR). Landfill leachate contained a concentration of organic matter between 3966 and 5090 mg COD.L-1 and no detectable amounts of sulfate. Reactors were started-up by feeding them wit

7. Utilização de mistura de solo saprolítico com bentonita na construção de revestimento de fundo de aterros sanitários. / Use of saprolite soil mixture with bentonite in the construction of landfill liner.
No Estado de São Paulo, a CETESB (1993), a exemplo da maioria das legislações e regulamentações ambientais em todo o mundo, recomenda que o coeficiente de permeabilidade da camada de impermeabilização de fundo de solo compactado (CCL ou compacted clay liner) em aterros sanitários seja menor ou igual a 10\ POT.-9\ m/s. O material mais utilizado para e

8. Caracterização de resíduos sólidos da construção civil para sua utilização em camadas drenantes de aterros sanitários / Characterization of construction waste for use as drainage materials in sanitary landfills
Intense population growth brings with it environmental concerns, since exploitation of natural resources, makes it essential to adopt recycling policies in order to achieve sustainable development. Therefore, this study sought to define a new application for recylcling construction and demolition waste (CDW-R). Two size distributions that could be readily pr

9. UtilizaÃÃo de Ensaios de Ecotoxicidade no Biomonitoramento de Efluentes de Etes Industriais, Hospitalares e De Aterro SanitÃrio, Localizadas no Estado do Cearà / Use of ecotoxicity tests on Biomonitoring of Industrial Effluents Etes, Hospital and Sanitary Landfill, located in the State of Ceara
Avaliou-se o uso de testes de ecotoxicidade com o organismo-teste Daphnia magna no biomonitoramento de efluentes de ETEs industriais (real e sintÃtico), hospitalares e de aterro sanitÃrio. Para tanto, foram selecionadas algumas ETEs a citar: Industrial Real (Sistema Integrado do Distrito Industrial â SIDI), Industrial SintÃtico (Reator anaerÃbio seguido

10. Recuperação da amônia liberada no processo de "air stripping" aplicado ao tratamento do lixiviado de aterros sanitários / Recovery of ammonia released from air stripping process applied to sanitary landfill leachate treatment
Sanitary landfill leachate is a pollutant liquid effluent mainly due to its high ammonia concentration. Its treatment is necessary due to environmental and labour legislation requirements, besides prevention of environmental impacts of leachate release in water bodies. This research proposes ammonia removal from leachate by air stripping process, which trans

12. Avaliação da ecotoxicidade de percolados em áreas de disposição de resíduos na região metropolitana de Natal/RN
Leachates are effluent produced by decomposition of solid waste, they have complex composition and can be highly toxic. Therefore such percolated liquid should be collected and treated properly to avoid environmental contamination of soil and of water bodies. The objective of this study was to evaluate the toxicity through ecotoxicological tests with Cerioda
