Biodegradation of a Tannery and Chemical Plant Producing Asetilsalisilikat Wastewater Mixture

Abstract

The oxygen uptake rate, (OUR), may be regarded as one of the most significant modeling tools for the understanding and interpretation of behavior of complex microbial cultures sustained under aerobic conditions. The wastewaters investigated in this study were obtained from a tannery and a chemical plant producing asetilsalisilikat, (ASS). The scope of the study, involved aside from conventional characterization, an assessment of significant kinetic and stoichiometric coefficients for chemical plant and tannery wastewaters and their mixtures, by using respirometric measurements. Results have shown that the addition of pharmaceutical effluents having a biodegradable character on tannery wastewaters would not therefore cause any negative effect on the biodegradability of tannery wastewaters.
