Abstract

A biochemical oxygen demand (BOD) sensor, based on an immobilized mixed cultures combined a Clark-type oxygen electrode, has been developed for the purpose of monitoring for industrial wastewater. The BOD sensor was based on a pre-tested designed microbial consortium, resulting in 4 min for one measurement followed by 8 min recovery time. Reproducibility of responses was blow 5.1%. The influence of pH, temperature and heavy metal ions was also discussed. Good agreement was achieved between the results of the sensor BOD measurement and those obtained from conventional BOD₅ analysis of several industrial wastewater samples.
