effects of antibiotics on specific methanogenic activity of anaerobic biomass
background: the antibiotics are excreted after their effect on the host body and together with other waste disposal are entered the treatment plant processes. antibiotics prevent the biological sewage treatment in the plant which consequently causes hazards to the environmental and human health. the purpose of this study was to investigate the effect of some popular antibiotics used by human an...
متن کاملinvestigating the inhibitory effect of polychlorinated biphenyls oils (pcbs) on anaerobic biomass by specific methanogenic activity (sma)
background: in this study, the inhibition rate of different oil concentrations containing pcbs (1242 and 1254 pcb arochlors) on the anaerobic biomass was investigated by specific methanogenic activity using the vials with volume of 120 ml. methods: original samples were divided into two groups: with soil containing pcbs and without pcbs and the control samples in both cases were just contained ...
متن کاملThe effect of operational conditions on the sludge specific methanogenic activity and sludge biodegradability.
The effects of hydraulic retention time (HRT) and influent COD concentration (CODInf) on Specific Methanogenic Activity (SMA) and the biodegradability of an anaerobic sludge need to be elucidated because of the discordant results available in literature. This information is important for the operation of anaerobic reactors and design of the sludge post-treatment unit. For this study, sludge sam...
متن کاملon anaerobic – aerobic treatment of industrial and municipal wastewater
Anaerobic–aerobic systems have been remarkably employed in industrial and municipal wastewater treatment for many years. While previously most treatment of wastewaters have been carried out in conventional anaerobic–aerobic treatment plants, in recent years, high rate anaerobic–aerobic bioreactors have been increasingly employed for wastewaters with high chemical oxygen demand (COD). This paper...
متن کاملMineralization of LCFA associated with anaerobic sludge: Kinetics, enhancement of methanogenic activity, and effect of VFA.
Long-chain fatty acids (LCFA) associated with anaerobic sludge by mechanisms of precipitation, adsorption, or entrapment can be biodegraded to methane. The mineralization kinetics of biomass-associated LCFA were established according to an inhibition model based on Haldane's enzymatic inhibition kinetics. A value around 1,000 mg COD-LCFA..g VSS(-1) was obtained for the optimal specific LCFA con...
