“…Eighty-five percent removal efficiency of COD was reported for treatment of hospital wastewater using an electro-bioreactor in combination with a tubesettler. [ 18 ] Another study investigating hospital wastewater treatment using fluidised aerobic bed bio-reactor in combination with tubesettler has reported 80–85% COD reduction. [ 15 ] BOD 5 removal from hospital wastewater was similar to COD, with 89% efficiency.…”

Hospital wastewater treatment is gaining attention in recent studies due to its complex nature. The performance of the sequencing batch reactor coupled with tube-settler was investigated for hospital wastewater treatment. The performance was evaluated regarding removing organic matter and nutrients (nitrate and phosphate). The phosphate was removed in the sequencing batch reactor and its associated tube-settler with a 60% removal efficiency margin. Nitrification was observed in sequencing batch reactor and tube-settler, but denitrification could not be achieved. The nitrification–denitrification process was not completed during the process. The current work’s main aim was to understand and optimise the operational parameters involved in the performance of the sequencing batch reactor. The operational parameters were optimised using Design expert software, and Response Surface Methodology involved a four-factor and five-level central composite design. The percentage removal of chemical oxygen demand, nitrate, and phosphate was selected to be observed during this study.

“…SBR performance was also investigated for specific constituents, e.g. levofloxacin, high strength N-methyl-2-pyrrolidone [ 18 ], 2,4 dichlorophenol and opium alkaloid (gamma radiation) [ 19 ]. Several studies have focused on the removal of pharmaceutical compounds from wastewater.…”

“…O seu descarte nas águas residuais é bastante preocupante, logo se faz necessário um tratamento devido a possíveis impactos ambientais negativos. Loh et al, 2018, estudaram uma maneira para tratar as águas residuais do processo de fabricação das membranas contendo uma maior concentração de NMP por um reator de batelada sequencial (SBR) como também por um biorreator de membrana (MBR). Os autores concluíram que o tratamento através do SBR foi capaz de remover mais de 90% de carbono orgânico dissolvido e aproximadamente 98% do NMP em 2 horas de experimento.…”

A aplicação de novas tecnologias e pesquisas em tratamento de águas são os caminhos para minimizar os impactos causados ao meio ambiente e melhoria dos recursos hídricos e, consequentemente, econômico e social de uma região. Dentre as tecnologias, se destacam os processos oxidativos avançados (POA’s), os quais são baseados na utilização de espécies altamente oxidantes para promover uma degradação mais eficaz do poluente a ser tratado. Este trabalho tem como objetivo realizar uma revisão dos POA’s, sendo eles: a fotocatálise com dióxido de titânio (TiO2)/ultravioleta (UV), foto-fenton e o peróxido de hidrogênio (H2O2)/UV, identificando os processos mais adequados de acordo com o poluente a ser tratado. Os POA’s se apresentam como uma opção para degradar os poluentes orgânicos que possuem elevada estabilidade química, devido à ineficiência de métodos comuns de tratamento de efluentes de difícil degradação. Além disso, os POA’s surgem como uma tecnologia onde apresenta uma maior eficiência no tratamento de efluentes a um baixo custo operacional. Portanto, os POA’s possuem um grande potencial para serem aplicados no tratamento de diversos efluentes obtidos a partir dos solventes utilizados na produção de membranas.

“…Loh, Wu, Ge, Pan, and Wang (2018) conducted a study of treatment of N‐methyl‐2‐pyrrolidone (NMP), a widely used solvent in polymeric membrane manufacturing, using an SBR and a submerged MBR. The SBR used a batch feed and intermittent aeration, whereas the membrane system was continuously fed and aerated.…”
