The present study explored the use of activated sewage sludge for microalgae harvesting and improving biogas production. Among the various sewage sludge to microalgae (S/A on % TS basis), 100% biomass ...

With the increasing complexity and scale of activated sludge process (ASP), it is quite challenging to coordinate the performance indices with different time scales. To address this problem, a ...

The applicability of this diagram was tested for the SBR with excellent results. The diagram could be applied to optimize the operation of wastewater treatment plants affected by problems with low ...

Scientists have developed an innovative solar-powered method to transform sewage sludge -- a by-product of wastewater treatment -- into green hydrogen for clean energy and single-cell protein for ...

Researchers have developed a simplified, sustainable method of converting sewage sludge from wastewater treatment into high-value activated carbon that can be used in a wide range of industrial ...

Extended aeration is part of an activated sludge process resulting in mixed liquor in which oxygen is used for wastewater treatment.

2 Modeling of activated sludge process 2.1 Benchmark ASP Secondary treatment plays a major role in treating wastewater in STPs. Secondary treatment consists of an aerobic bioreactor for aeration ...

This study entitled "Responses of microbial interactions to elevated salinity in activated sludge microbial community" is published in Frontiers of Environmental Science & Engineering.
