Effect Of Operating Conditions On Steady-State Behavior Of Activated Sludge In Phenolic Waste Water Treatment

open access: yesReaktor, 2017
Steady-state behavior of activated sludge in phenolic waste water treatment was observed and theoretically considered. The apparatus used in  this experiment was a continuous perfect mixing tank where activated sludge was withdraw continuosly and auto ...

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.

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)

Primary and Activated Sludge Biogas Production: Effect of Temperature

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2018
Sewage sludge management is a problem of growing importance. Anaerobic sewage sludge stabilization is commonly used technology, where organic matter contained in primary and activated sewage sludge is converted into biogas, so both, pollution control and

Development of microbial communities in biofilm and activated sludge in a hybrid reactor

open access: yesScientific Reports, 2022
Microorganisms play a key role in biological wastewater treatment. The form in which biomass develops determines the efficiency and mechanisms of organic compound conversion, due to different conditions in various microbial structures.
