This study aimed to produce polyhydroxyalkanoates (PHAs) from organic wastes by mixed bacterial cultures using anaerobic-aerobic fermentation systems. Palm oil mill effluent (POME) was used as an organic source, which was cultivated in a two-step-process of acidogenesis and acid polymerization. POME was operated in a continuous flow anaerobic reactor to access volatile fatty acids (VFAs) for PH...
This review summarizes progresses in research on municipal wastewater treatment using anaerobic membrane bioreactors (AnMBR). At first, the AnMBR process options including membrane configuration and mean pore size or type are introduced. Next, many factors affect AnMBR performance in treating municipal wastewater, so this paper mainly focuses on the membrane characteristics, temperature, hydrau...
Millions of tonnes plastic litter end up annually in the environment causing damage to ecosystem. There are currently no standards regulating amount microplastic wastewater, and question is, should there be? Answering this requires an understanding damages causes its removal potential from wastewater. This paper examines cost-effectiveness three wastewater treatment (activated sludge, rapid san...
anaerobic digestion is a feasible technology to stabilize the solid waste generated inslaughterhouses obtaining significant quantities of biogas, considered as a clean and renewable fuel. this iswhy it is important to optimize the digestion process in order to eliminate organic matter and maximize theproduction of biogas. in this work, a system was developed for treating slaughterhouse solid wa...
The aim of this study is to prepare biogenic sulphides by using bacteria for the removal of zinc cations from their solutions. The production was realized in a bioreactor under anaerobic conditions at 30 °C. Sorbents were prepared by sulphate-reducing bacteria in different nutrient medium modifications, under two modes of bacteria cultivation. Created precipitates of iron sulphides were removed...
