Municipal biosolids (MBs) that are land-applied in North America are known to possess an active microbial population that can include human pathogens. Activated sludge is a hotspot for the accumulation of antibiotics and has been shown to be a selective environment for microorganisms that contain antibiotic resistance genes (ARGs); however, the prevalence of ARGs in MBs is not well characterize...

• Thermophilic dry digestion of DDS increases methane yield by 6% at 52 °C efficiently converts organic N. is stable high free ammonia levels (2 g/L) Increasing level enriches members the methanogenic family WSA2. Sanitization thermophilic has a positive energy balance. This study investigated possibility to use anaerobic solid dewatered digested sewage sludge (DDS) wastewater treatment plant (...

Abstract The continuous and rapid growth of sewage sludge (biosolids) from wastewater treatment plants (WWTPs) poses both economic environmental challenges. In many cities Russia, the situation has exacerbated with time. this study, three state-of-the-art biosolid management technologies, namely windrow composting (WC), tunnel (TC), lime stabilization (LS), were evaluated for their feasibility ...

most of electricity is generated by thermal power plants in iran. shahid rajaee thermal power plant consists of four 250mw natural gas and fuel oil burning units that is located at 100 km west off tehran. as a result of fuel oil burning in winter time, boilers air heaters are washed and cleaned frequently. the wastewater originating from air heater washing contains suspended solids and differen...

A high solid digester with dewatered sludge was operated for 110 days to ascertain the interactions between bacterial and archaeal communities under ammonium stress, as well as the corresponding changes in bio-degradation mechanisms. The volatile solids reduction (95% confidence intervals in mean) changed from 31.6 ± 0.9% in the stable period (day 40-55) to 21.3 ± 1.5% in the last period (day 7...

New Delhi metallo-β-lactamase-1 (NDM-1) producing Escherichia coli constitute a serious threat to global health since it is found to be highly resistant to most of the currently available antibiotics including carbapenems. Gram-negative bacterial strains with NDM-1 (New Delhi Metallo-beta-lactamase-1) gene, also called the superbug, detected in Ganges water. The New Delhi metallo-β-lactamase (N...
