The discharge of excess nitrogenous pollutants in rivers or other water bodies often leads to
serious ecological problems and results in the collapse of aquatic ecosystems. Nitrogenous …

This study compares the performance and microbial composition of a conventional activated
sludge process (ASP) with a modified trickling filter (MTF) for urban sewage treatment. MTF …

Bacterial diversity and community composition are of great importance in wastewater
treatment; however, little is known about the diversity and community structure of bacteria in …

Volatile fatty acid recovery from waste activated sludge (WAS) was highly suggested to
supplement carbon source for nitrogen removal. However, it was not easy to separate them …

The study investigated the mechanisms and microbial communities underlying the long-term
stability and removal performances shown by aerobic granular sludge (AGS) reactor …

Membrane bioreactors (MBRs) have become one of the most promising technologies in
wastewater treatment. This study aimed to investigate the emission characteristics, source …

Strong hydraulic selection pressure is a control co-factor for maintaining the stability of
granular sludge in a continuous-flow bioreactor. In this study, efficient nitrogen removal was …

The main aim of this study was to develop a new biotreatment process for denitrification by
using a small bioreactor platform (SBP) for macro-encapsulation of a bacterial consortium …

The prediction of the chemical oxygen demand (COD) and total nitrogen (TN) in integrated
anaerobic–anoxic–oxic (A2O) and anoxic–oxic (AO) processes (ie, A2O+ AO process) was …

Biological trickling filtration (BTF) has the advantages of simple operation, low energy
consumption, and low sludge production, and its application in the treatment of domestic …
