I am looking for assistance in finding a formula to find Aerobic Digester VSS Destruction % formula based on SRT, VSS, and nbVSS, Kd. I came across a formula containing above parameters, but I couldn't find the same formula containing nbVSS in any of the reference such as Metcalf Eddy, or WEF MOP.
The Formula used was VSS destruction%=(MLVSS load-nbVSS load)/MLVSS Load * kd * SRT /(1+kd*SRT)
