Aerobic granular sludge (AGS) is a special type of biofilm formed by the self-aggregation microorganisms and extracellular polymers considered promising technology for wastewater treatment. However, new strategies are still being proposed as to how improve polymeric substances (EPS) production that influences formation AGS. Recently, acceleration aerobic granulation using autoinducers such N-ac...

The presence of volatile methyl siloxanes (VMSs) presents challenges for using landfill and digester gases as energy fuels because of the formation of silicon dioxide deposits during combustion. This study looks at the feasibility of using biological treatment to control VMSs. Biotrickling filters removing octamethylcyclotetrasiloxane (D4), selected as a model VMS, from aerobic and anaerobic wa...

[Purpose] There are various treatment modalities for fibromyalgia syndrome (FMS), which is characterized by widespread pain and fatigue. The aim of this study was to investigate the effects of aquatic, aerobic and isometric strength-stretching exercises on the physical and psychological parameters of patients with FMS. [Subjects and Methods] Seventy five female patients with FMS were randomly s...

The biological treatment of the organic fraction of municipal solid waste represents the most spread strategy to pursue the biological stabilization of this residual stream, under either aerobic or anaerobic conditions. Anaerobic digestion is an attractive technology for the conversion of organic substrates into methane, but the handling of the residual stream, namely the digestate, can prove t...

Sludge management accounts for approximately 60% of the total wastewater treatment plant expenditure and laws for sludge disposal are becoming increasingly stringent, therefore much consideration is required when designing a solids handling process. A membrane thickening aerobic digestion process integrates a controlled aerobic digestion process with pre-thickening waste activated sludge using ...

The presence of emerging biological pollutants in treated wastewater effluents has gained attention due to increased interest in water reuse. To evaluate the effectiveness of the removal of such contaminants by the conventional wastewater treatment process, the fate and decay kinetics of NDM-1-positive Escherichia coli strain PI7 and its plasmid-encoded antibiotic resistance genes (ARGs) were a...
