The Hemisphere of the Americas is among the...

A política de importar água de bacias cada vez mais distantes para satisfazer o crescimento da demanda começou há mais de dois mil anos com os romanos, dando origem aos seus famosos aquedutos. A prática ainda persiste, resolvendo, precariamente, o problema de abastecimento de água de uma região, em detrimento daquela que a fornece. As soluções mais...

In this paper, the performance of a Submerged Membrane Bioreactor operated with pure oxygen was evaluated with respect to permeate quality and membrane fouling, having a Conventional Aeration Membrane Bioreactor (C-MBR), operating in parallel, as a control system. Regarding permeate quality, although both systems were able to achieve high removal e...

In this paper, the influence of biofilm carriers in a MBR on the performance of organic matter and nitrogen removal and the influence on membrane fouling were evaluated. The configurations studied included a Conventional Membrane Bioreactor (C-MBR) and a Biofilm Membrane Bioreactor (BF-MBR) operated in parallel, both fed with domestic wastewater. R...

Treatment technology for wastewater treatment and reuse encompasses a vast number of options, and the Submerged Membrane Bioreactor is regarded as a key element for the role it can play in water reuse schemes. Thus, this study aimed to present and discuss the current status of sMBR implementation, as well as to present the results of a pilot plant...

The present study evaluated the removal of TOC from an effluent with high organic load resulted from the treatment of oil-water emulsion by thermal process. Hollow Fiber Ultrafiltration membrane (HF-UF) and physicochemical clarification process were used as pretreatment options to assess the influence of feed effluent quality on the UV/H2O2 oxidati...

In this work it is presented the results of bench scale tests using Advanced Oxidation Process (AOP) in a UV/H2O2 system, for the treatment of an industrial effluent with a high concentration of dissolved organic matter, resulted from thermal treatment of oil-water emulsions.

DALYs are a measure of the health of a population or burden of disease due to a specific disease or risk factor. It evaluates the time lost because of disability or death from diseases compared with a long life free of disability in the absence of disease. DALYs are calculated as the sum of years of life lost by premature mortality (YLL) and years...

This paper presents the results of a research on direct drinking water treatment through an ultrafiltration pilot plant unit using spiral-wound membranes (3500 MWCO).
