WebA formulation to calculate the mean cell residence time (MCRT or sludge age) of unsteady-state activated sludge systems is presented. The formulation was studied by applying it to data generated by computer simulation and to data obtained from an actual wastewater treatment plant. WebThe sludge age SRT is probably the most important key figure in the activated sludge process. The SRT corresponds to the average residence time of the microorganisms in …
WebJan 1, 1988 · The Dynamic Sludge Age Parameter The development of a f ormu latio n to comput e the t rue average sludge age in a dynamic system makes con trol base d on sludge age po ssible, and also provides a basis for the comparison of contr ol algorith ms. WebApr 11, 2024 · It could be seen from Table 2 that the protein content in sludge was mostly 20 ~ 30%. The differences of protein content might be caused by the differences of sewage sources, properties, and treatment processes (Peng et al. 2012; Chen et al. 2024).It is assumed that the influent of WWTPs contains industrial wastewater and sewage with …
WebThe application discloses a method for accurately controlling dynamic sludge age of a sewage treatment plant. The method can comprise the following steps: determining a daily surplus sludge discharge quality theoretical value; automatically controlling an excess sludge pump according to a daily excess sludge discharge quality theoretical value; and … WebThe Dynamic Sludge Age (DSA) program computes the "true" mean cell residence time for an activated sludge plant which is not at steady-state. Shift-Click to download documentation and programs to perform this calculation: DSA.EXE- This is an executable program to compute the DSA. DSA.WK1- This is a spreadsheet to compute DSA.
