Disintegration of excess activated sludge
by hydrogen peroxide oxidation, Desalination, 246: 275-284.
But the performance of activated sludge
system with extended aeration in removing cysts and parasite eggs were more than the activated sludge
system with conventional aeration.

The proportion of (volume basis) primary and waste activated sludge
The rate of biodegradation of phenolic compounds depends on the properties of activated sludge
(floc composition and size, biomass concentration, microbial community and their metabolic potential), temperature, the concentration and the properties of the substrate.
is a well-known biomass used for the purification of some industrial effluents and domestic wastes.
3] had the highest efficiency in dewatering the returned activated sludge
Concentration amounts were higher in effluent from STPs that used traditional activated sludge
treatment; in contrast, effluent from plants that used advanced ozonation as tertiary treatment contained significantly lower OC levels (37.
The pollution was due to activated sludge
, which is used in the sewage treatment process.
Current wastewater treatment options include membrane bioreactor, activated sludge
, fixed film or on-site septic systems.
From the screen the wastewater enters the MBR treatment tank where the mixed liquor activated sludge
degrades the COD (Chemical Oxygen Demand).
A mixture of aerobic activated sludge
and a mineral-medium (MgS[O.
These open channel configurations are tolerant of high solids streams, including food waste and the activated sludge
from membrane bioreactors.
Many studies have shown the presence of antiviral components in mixed liquor of activated sludge
even in the liquid and solid phases (Arraj, Bohatier, Laveran, & Traore, 2005; Knowlton & Ward, 1987; Ward, 1982).
This presents a serious challenge for the classical activated sludge
and sequence batch reactors.
