Activated sludge waste water processing is one of the most common technologies used in municipal waste water treatment facilities. Bioregenerative waste water treatment research at the NASA Johnson ...

The study investigated the unbiodegradable fraction of particulate chemical oxygen demand (PCOD) in thickened waste activated sludge (TWAS) using semicontinuous-flow completely-mixed anaerobic ...

The field of microbiological treatment of sludge is experiencing rapid development due to increasing environmental pressures and a global drive towards ...

The United States generates seven million tons of sewage sludge annually, enough to fill 2,500 Olympic-sized swimming pools. While a portion of this waste is repurposed for manure and other land ...

Two continuous-flow bench-scale reactors (one of them was control) were built up to study the impact of the shock loading of CNTs (Carbon Nanotubes) on the activated sludge wastewater treatment ...

The United States generates seven million tons of sewage sludge annually, enough to fill 2,500 Olympic-sized swimming pools. While a portion of this waste is repurposed for manure and other land ...

Researchers in the United States have discovered an efficient, cost-effective way to make biodegradable plastics from unused and potentially polluting waste. The process makes use of bacteria found in ...
