Potential of ultrasound treatment for sludge reduction [PDF]

open access: yes, 2008
The potential of ultrasound treatment for sludge reduction during the activated sludge process was assessed. Batch and dynamic disintegration studies were completed using an activated sludge pilot-scale plant fed with settled sewage that was comprised ...

Standardization of activated sludge for biodegradation tests [PDF]

open access: yes, 2011
Activated sludges are an inoculum source commonly used in biodegradation studies, as wastewater treatment facilities constitute an entry point to the environment for many chemicals.

Effect of polyethylene terephthalate particles on filamentous bacteria involved in activated sludge bulking and improvement in sludge settleability

open access: yesScientific Reports, 2023
Excessive proliferation of filamentous bacteria within activated sludge leads to sludge structural instability and diminished settling properties, which is a prevalent issue in tannery wastewater treatment. Based on available information, there is a lack

The bacteriology of activated sludge [PDF]

open access: yesEpidemiology 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.

Ultrasound-induced settleability and membrane filterability of activated sludge treating milk processing wastewater

open access: yesApplied Water Science, 2018
In practice, established operation of activated sludge treatment system with high biomass concentration is restricted because of difficulty in settling the sludge in clarifiers.

Pathogenic micro-organisms in waste waters from daiies

open access: yesCzech 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)
