In this study, some important biokinetic parameters of industrial wastewater were assessed by a locally fabricated multichannel respirometric device. A revised theoretical approach has also been incorporated in the determination of biokinetic coefficients (yield coefficient, reaction rate and biodegradability) using the concept of headspace gas respirometry. Wastewater samples from different industrial sources were studied by the device in presence of freshly cultured seed inoculums as biomass agent. It is found that the results obtained from the respirometric bioassay can easily evaluate the overall operation and treatment efficiency achieved by an industrial effluent treatment plants (ETPs).
