For wastewater treatment process (WWTP), mechanism model for activated sludge process (ASP) is unsuitable for estimating the effluent COD (Chemical Oxygen Demand) as the parameters of ASM ( Activated ...
Neural networks (NNs) were used to predict the onset of filamentous bulking, as described by trends in stirred sludge volume index, in a pulp and paper activated sludge treatment system. Variables ...
of the conventional activated sludge models yet. This work aims to develop a mechanistic mathematical model to evaluate the BNR process after resolving such a problem. A mathematical model is developed based ...
bacterium. A novel dynamic model was developed and tested to simulate the response of all four key process variables: the bulk phenol concentration, the suspended biomass concentration, the concentration ...
distribution function could improve the population balance model for activated sludge flocculation and successfully predict the dynamic changes in volume percentage distribution and mean floc size of activated ...
to be resolved. Thus, elucidating the factors that affect community assembly in the bioreactors is necessary for predicting fluctuations in community structure and function. For this study activated sludge samples ...
to as integrated fixed film activated sludge or IFAS) was operated at 15 °C on aerobically pre treated municipal wastewater (23 mgNH4-N·Lâ1). Ammonium oxidizing bacteria (AOB) and NOB were ...
per annum by 2005/6 [1,2]. Sludge application in combination with other widely used soil improvement treatments (e.g. liming) has effects on soil biogeochemical processes and presumably microbial ...
. The spreading pressure of the sludge sorption process decreased as the temperature increased at a given water activity and increased as the water activity increased at a given temperature. When the spreading ...
to control the quality of activated sludge systems [3, 14]. This index correlates presence and abundance of protozoans, amoebas, and metazoans with quality of the waste and the biological process and has been ...
