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 ...

A new process, the biofilm-activated sludge innovative nitrification (BASIN) process, consisting of a moving-bed biofilm reactor (MBBR) with separate heterotrophic wasting, followed by an ...

Important factors that control the fate of heavy metals in the activated sludge process were studied in laboratory reactors. Because heavy metal adsorption by activated sludge results from the ...
