2. Removal of organic matter from pre-treated domestic sewage in anaerobic biological reactor by a combined system of electrolytic and biological aerobic treatment
Resumo Os processos biológicos são os métodos mais difundidos para o tratamento de águas residuárias. No entanto, eles têm limitações para degradar poluentes tóxicos e refratários, contaminantes, que os processos eletroquímicos podem remover. Portanto, o objetivo da pesquisa foi verificar a possibilidade de tratamento de esgoto por um processo bio

3. RESEARCHING NEW WAYS TO REDUCE N2O EMISSION FROM A GRANULAR SLUDGE SEQUENCING BATCH REACTOR TREATING DOMESTIC WASTEWATER UNDER SUBTROPICAL CLIMATE CONDITIONS
ABSTRACT N2O emissions from wastewater treatment plants have become an important issue, since this compound is a significant greenhouse gas that affects the sustainability of sewage treatment. This work aimed to investigate and to reduce N2O emission from a pilot-scale aerobic granular sludge sequencing batch reactor (AGS-SBR) operated for carbon and nitroge

4. The effect of temperature on the efficiency of aerobic biodegradation of sugar beet distillery stillage: Removal of pollution load and biogens
Abstract Beet stillage is a high-strength effluent from the production of ethanol from sugar beet. A large annual volume of sugar beet stillage requires finding new effective ways for its utilization. The aim of the study was to investigate the effect of temperature on the efficiency of aerobic biodegradation of beet stillage. Biodegradation was carried out

5. Sequencing batch reactor operation for treating wastewater with aerobic granular sludge
In this work, the performance of a sequencing batch reactor (SBR) on aerobic granular sludge was studied for urban wastewater treatment. The system was inoculated with aerobic activated sludge collected from a wastewater treatment plant and, after 30 days of operation, the first granules observed had an average diameter of 0.1 mm. The biomass concentration r

6. The stimulating effects of the addition of glucose on denitrification and removal of recalcitrant organic compounds
A laboratory scale aerobic oxidation ditch combined with an anoxic reactor was conducted to treat wastewater from a chemical industrial park in Tianjin, China. The wastewater exhibited a low biodegradability, and the results of gas chromatography mass spectrometry (GC-MS) analysis showed that some recalcitrant organic components are present in the wastewater

7. Tratamento de corantes reativos em solução aquosa utilizando lodo de esgoto sanitário como biossorvente em reatores contínuos. / Treatment of reactive dyes in aqueous solution using sewage sludge as biosorbent in continuous reactors.
Conventional treatments of textile industry effluents usually produce significant amounts of recalcitrant subproducts. Among the new treatment technologies, adsorption appears as an alternative method. In this study, the efficiency of sewage sludge in the removal of reactive dye yellow GR, blue GN and red RB was evaluated to pH, total alkalinity, volatile fa

8. Recuperação de enxofre elementar em reatores microaerados / Sulfur recovery in micro-aerobic reactors
The occurrence of biological sulfate reduction results in the formation of unwanted hydrogen sulfide, which can be removal under oxygen-limiting conditions. Detailed knowledge of this process remains unclear and the micro aeration process was prevented by technological limitations. For these reasons, the chemical and biological oxidation of sulfide was studi

10. BIOAUMENTAÇÃO EM REATORES ANAERÓBIO E AERÓBIO E USO DE REATOR NITRIFICANTE PARA REDUÇÃO DA CARGA ORGÂNICA E NITROGENADA / BIOAUGMENTATION IN THE ANAEROBIC AND AEROBIC REACTORS AND USE OF NITRIFIER REACTOR FOR THE REDUCTION OF ORGANIC AND NITROGEN LOADS
Efluentes agroindustriais são capazes de causar grande impacto em corpos dágua se lançados sem tratamento adequado. A remoção da carga orgânica nos tratamentos biológicos convencionais é conseguida com elevada geração de lodo residual e consumo energético. As técnicas usuais de remoção biológica da carga nitrogenada demandam altos custos com i

11. Ex-situ bioremediation of Brazilian soil contaminated with plasticizers process wastes
The aim of this research was to evaluate the bioremediation of a soil contaminated with wastes from a plasticizers industry, located in São Paulo, Brazil. A 100-kg soil sample containing alcohols, adipates and phthalates was treated in an aerobic slurry-phase reactor using indigenous and acclimated microorganisms from the sludge of a wastewater treatment pl

12. Estudo da tratabilidade de efluente de reator anaeróbio e lixiviado de aterro sanitário utilizando o processo de lodos ativados / Treatability of the anaerobic effluent and landfill leachate using activated sludge process
Embora em alguns países como os europeus, o aterro sanitário como forma de disposição final de Resíduos Sólidos venha perdendo espaço, entre nós essa técnica é ainda largamente empregada. O lixiviado gerado nos aterros sanitários apresenta grande potencial poluidor, devido à presença de matéria orgânica, rica em substâncias húmicas e matéri
