On-line monitoring of active biomass concentration in wastewater treatment plant using a potentiometric microbial biosensor

0

A conductometric method was developed for the quantification of microbial biomass, required for monitoring the operational condition of wastewater treatment plant. The conductometric microbial biomass measurement has been shown to be reproducible with respect to the data obtained over a number of days, and retains stability for a minimum period of at least 3-5 d before recalibration of the biomass measurement is required. Activated sludge plant has shown a minimum variation in efficiency with respect to biomass concentration as 8 to 12% at ± 13 mg L-1. Largevariations were observed only for the biofilter, ranging from 15 to 20%, at ± 35 mg L-1. The upflow anaerobic sludge blanket reactor and membrane bioreactor were observed within the ranges, as found for activated sludge plant and biofilter. Based on the observations of the field measurements, it was found that the conductivity based biomass measurement systems were significant in detecting and monitoring the process performance of suspended growth biological treatment processes
