Journal ArticleDOI
Nitrogen removal via nitrite from municipal wastewater at low temperatures using real-time control to optimize nitrifying communities.
TL;DR: The obtained results showed that high nitrogen removal efficiency with effluent total nitrogen below 3 mg/L could be achieved and that the nitrifying microbial communities were optimized.
Journal ArticleDOI
Enzyme activities under anaerobic and aerobic conditions in activated sludge sequencing batch reactor
TL;DR: It was established that, even though synthesis of the enzyme is to some extent affected depending on the anaerobic and aerobic incubation, it is the stable and the floc bound nature of these extra-cellular enzymes which results in no significant difference in enzyme activity under anaerilic and aerobic phase of a steady state operated single sludge anaerobia–aerobic system.
Journal ArticleDOI
Uptake of Organic Substrates and Accumulation of Polyhydroxyalkanoates Linked with Glycolysis of Intracellular Carbohydrates under Anaerobic Conditions in the Biological Excess Phosphate Removal Processes
TL;DR: Redox balance was found to be a factor regulating the anaerobic uptake of substrates and their further metabolism and Glycogen seemed to serve not only as a source of reducing power necessary for the redox balance regulation but also as an important energy source, because glycolysis can provide both reducing power and energy.
Journal ArticleDOI
Production of polyhydroxyalkanoates (PHA) by activated sludge treating municipal wastewater: effect of pH, sludge retention time (SRT), and acetate concentration in influent.
TL;DR: It was found that activated sludge with an SRT of 3 days possessed better PHA production capability than sludgeWith an S RT of 10 days, while sludge acclimatized with only municipal wastewater achieved 20% of sludge dry weight.
Journal ArticleDOI
Deterioration of enhanced biological phosphorus removal by the domination of microorganisms without polyphosphate accumulation
TL;DR: In this paper, microbial metabolism in the activated sludge of a failed enhanced biological phosphorus removal process was investigated to clarify the cause of the failure, indicating that the dominant microorganisms in the sludge consumed carbohydrates in the uptake process of acetate or propionate under anaerobic conditions.
