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.

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 ...

Titan Mem-Box is a compact, packaged membrane system that converts conventional activated sludge treatment plants into ...

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 ...

Pilot and full-scale isolation investigations, including examination of final clarifier failure mechanisms, were used to formulate an operating strategy to maximize the performance of an activated ...

Multi-year improvement project modernizes clarifiers and activated sludge tanks to support long-term operational performance.
