primary and secondary high rate algal pond length x width x height is 16m x5m x0.7m, effective water depth are the 0.5M, the use of mixed liquid in the subsurface-flow thruster pool in the spiral flow state can reduce photo-inhibition effects on algae growth, domestic sewage water for ...
2.2 Secondary sludge Secondary sludge, also known as waste activated sludge (WAS), or biosludge, is a high-protein byproduct (biosolids) produced in the wastewater treatment plant, where microorganisms decompose and remove organic substances from wastewater. Activated sludge processes (ASPs) are widel...
Especially in recent decades, researchers have mainly used computational fluid dynamic (CFD) simulations or numerical analyses to study solids removal in STs for sewage treatment. For example, Ghawi & Kriš [30] looked at the improved performance of secondary ST using a CFD model. Mohanarangam ...
Explain how the major objectives of sewage treatment are met through the major processes of sewage treatment. What are biofilms and how do they impact human health? In what ways are soils involved in the greenhouse effect that is leading to global climate change? D...
In a pilot-scale treatment using microscreened primary treatment and anaerobic secondary treatment with a second-generation staged anaerobic fluidized membrane bioreactor system, Shin et al. [9] showed that ≥ 87 % chemical oxygen demand (COD) removal, 99 % suspended solids (SS) removal and ...
Typically, in a sewage treatment plant, the activated sludge is the biological process in which one or several of the following steps take place: Oxidizing carbonaceous biological matter Oxidizing nitrogenous matter such as ammonium and nitrogen in biological matter ...
