Predicting the fate and the biological treatment parameters of phenol in a wastewater from its initial concentration

Abstract Microbial degradation is an important process for removing many organic chemicals from natural waters. The estimation of biodegradability which reach the aquatic environment necessary in assessing hazard associated with their use. Phenol has industrial applications and it finds its way into wastewater streams. It toxic to several biochemical reactions. However, biological transformation phenol non-toxic entities possible. In this article, data biodegradation at different concentrations were studied. For equal or less than 147 mg/L, plateau (the stage termination carbon) BOD (biochemical oxygen demand) was calculated be 169.47% corresponding initial concentration, biomass produced up 70% concentration. This study shows that plateau, BOD, ultimate can all estimated mg/L just if concentration known without having repeat time-consuming experiments.
