Resumo O lançamento indiscriminado de nutrientes em corpos hídricos pode levar ao processo eutrofização desses corpos. Assim, deve-se buscar a remoção prévia nitrogênio e fósforo. Uma alternativa que desempenhar satisfatoriamente esse papel são as lagoas polimento bateladas sequenciais (LPBS) no pós-tratamento upflow anaerobic sludge blanket (UASB), uma vez nessas o pH tende se elevar, podendo ...

Waste containing explosive chemicals are hazardous to the environment. We suggested and implemented a hybrid approach for destruction of nitrocellulose-containing sewage sludge (NCS) from real chemical industrial complex. Combining alkaline hydrolysis mesophilic anaerobic digestion in up-flow blanket (UASB) reactor allowed us successfully achieve balance between environmental safety economic ef...

Sulfate-reducing bioreactors for sulfide production are the initial stage of processes targeting elemental sulfur recovery from sulfate-rich effluents. In this work, principal reactions involved in glycerol fermentation and sulfate reduction using its products as electron donors were assessed together with their specific consumption/production rates. A battery batch activity tests without perfo...

Reuse of treated wastewater for irrigation purposes is a measure to reduce water stress and overexploitation freshwater resources. This study aims investigate the environmental economic impacts current conventional treatment plant (WWTP) in Peschiera Borromeo (Milan, Italy), compare possible scenarios enable reclaimed reuse agriculture. Accordingly, we propose alternative disinfection methods (...

we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...
