Abstract

A low-cost differential manometric respirometer was fabricated to assess the biodegradability of industrial wastewater. Test samples were collected from four different industrial sources i.e. dairy, tannery, pharmaceutical and dyeing industry. In this study, various parameters such as ultimate oxygen uptake (OU∞), reaction rate constant (k), seed dependent biodegradability (αs) and relative oxygen uptake rate (R%) were calculated to assess the overall biodegradation criteria of the wastewater samples. Respirograms were plotted to evaluate the oxygen uptake rate (OUR) profile. Rate of biodegradation was found maximum for dairy industrial source while sample from dyeing industry exhibited retardation effects on the microbial biodegradation process.
