Mean cell residence time
  • Also called sludge age (θC) or Solid Retention Time (SRT)
  • θC= (Mass of suspended solid in the system)/(Mass of solids leaving the system per day)
  • Mean cell residence time is an operational parameter related to Food to Microorganism ratio (F/M)
F/M ratio express BOD (Biochemical Oxygen Demand) loading with regard to microbial mass in the system
