The bacteriology of activated sludge [PDF]
Epidemiology and Infection, 1944 Homogenization of activated sludge greatly increased the apparent bacterial count obtained by plating on a solid medium, and for this reason facilitated the isolation of the predominant flora by liberating the bacteria from the interior of the sludge flocs.

Pathogenic micro-organisms in waste waters from daiies
Czech Journal of Food Sciences, 2000 Waste waters from dairies were tested for the presence of bacterial pathogens - Listeria monocytogenes, Staphylococcus aureus and Salmonella spp. The prevalence of bacteria was investigated in each stage of the cleaning process (activated sludges systems)

Angewandte Chemie, EarlyView.HEO‐regulated electronic structure drives nonradical PI activation, promoting ETP‐mediated polymerization of 4CP into high‐molecular‐weight products with enhanced surface enrichment. Concurrent dechlorination occurs via radical coupling and •OHads attack, enabling efficient carbon retention and selective product evolution at the liquid–solid interface.
