Cross-linked and quaternized pine sawdust was tested for vanadium removal from a synthetic aqueous solution as well as from real industrial wastewater which had a considerable amount of vanadium and other ions such as sulphate, ammonium and nickel. The maximum vanadium sorption capacity of the modified pine sawdust was found to be 130 mg/g in synthetic solution and 103 mg/g in real wastewater. ...

introduction population growth, increasing consumption of natural energy sources, the increasing use of fossil fuels, especially the oil and gas industry in recent years with the energy imbalance management has led to emergence of global energy crisis. moreover, rapid urbanization and industrialization have substantially increased the amount of high-strength wastewater being produced, which in ...

aims: the effect of electrochemical process on polyphosphate alone has not been yet investigated. the aim of this study was to study polyphosphate removal from synthetic wastewater by electrochemical process.  materials & methods: this research was carried out experimentally on 50 samples of synthetic wastewater. in each run 2000ml of sw took place in a batch. a constant 600ma direct current wa...

Methanogenic community structure and dynamics were investigated in two different, replicated anaerobic wastewater treatment reactor configurations [inverted fluidized bed (IFB) and expanded granular sludge bed (EGSB)] treating synthetic dairy wastewater, during operating temperature transitions from 37°C to 25°C, and from 25°C to 15°C, over a 430-day trial. Non-metric multidimensional scaling (...

Background : Pseudomonus stutzeri bactrerium is one of the most important and effective denitrifier bacteria in wastewater. With regard to the importance of effects of nitrate on water resources and human health and role of metronidazole inhibition, this study was done with the aim of survey of effect of metronidazole different concentrations on biological denitrification of Pesudomonas stutzer...

The dairy industry is one of the main sources agro-industrial wastewater [...]

The authors conducted a study on treating synthetic dairy wastewater using aerobic granular sludge (AGS) in laboratory-scale continuous flow reactor (CFR) system. system consisted of an anaerobic reactor, and settling sedimentation tank, with different hydraulic retention times tested over 90-day period. monitored characteristics effluent treatment performance found that the achieved excellent ...

Wastewater from concentrated animal feeding operations (CAFOs) frequently contains high concentrations of steroid estrogenic hormones. Release of these hormones into the environment may occur when CAFO wastewater is applied to agricultural lands as a nutrient and water source for crop production. To assess the potential risk of hormone contaminants derived from animal wastewater, we investigate...

the microbial fuel cells (mfcs) are a kind of systems through which the anaerobic bacteriaalong with the oxidation of simple or complicated organic matter in the wastewater can generate the electricpower. this is a modern approach used in generation of the clean and renewable energy. in this research, two pilot laboratories of double-chamber microbial fuel cells were made. one of them contained...
