Effective wastewater treatment relies on the recycling of activated sludge (RAS) to sustain microbial activity in aeration ...

Australian-based process contractor, Environmental Solutions International (ESI), has recently completed the commissioning of a new WwTP at South Caboolture in Queensland, based upon its BNR process.

Solids retention time (SRT), biological scum trapping and recycle, and the dynamic equilibrium between Nocardioform populations in the foam and the mixed liquor are the controlling factors in ...

Activated sludge mass in systems without primary sedimentation is composed of biomass and primary suspended solids, both composed of organic degradable, organic non-degradable, and mineral components.

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 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 ...

Next-generation Sequencing Bath Reactors are rapidly making inroads into WwTWs. Ian Sully takes an in-depth look at the technology, and reveals how it is being used at Wessex Water's Charmouth site.

Their analysis is published in the journal Frontiers of Environmental Science & Engineering on December 20, 2023. The coronavirus disease (COVID-19) pandemic has triggered a major increase in the use ...
