Seasonal community structure and regionally synchronous population dynamics have been observed in natural microbial ecosystems, but have not been well documented in wastewater treatment bioreactors.

The pattern of flow into the system, the recycle flow, and the mixing within the system are important parts of the hydraulic regime of activated sludge systems. In this investigation, optimization ...

Research was undertaken to develop a model for activated sludge, integrated fixed-film activated sludge (IFAS), and moving-bed biofilm reactor (MBBR) systems. The model can operate with up to 12 cells ...

The pandemic has triggered a major increase in the use of medical facilities and drugs, which has exacerbated pollution in wastewater biochemical treatment systems. Pollution from environmental rare ...

Given that previous studies have neglected the potential mechanism of the difference in aluminum content affecting the activated sludge system, the research team from Wuhan University of Technology ...
