Investigation of the Treatment of Wastewater Using Activated Sludge Process

Abstract:

The treatment of wastewater with activated sludge process has been received with a great attention for decades. However, the effective application of this field is not as widely spread. In this study, the treatment of wastewater was investigated, and samples were collected and ascertained. The process operation was monitored and major observation and findings were noted. Consistent pH of 7.4 was almost maintained. High nutrients removal efficiency was sustained with low concentration of nitrates and phosphates in effluent wastewater. Suspended solids removal was satisfactory, although undesired spike of 19 mg/l and three undesired values beyond >15mg/l were measured. The micronutrient metals such as Al and Zn were found to be high with highest concentration of 113600 mg/kg and 940 mg/kg. The maximum concentration of 300 mg/kg and 332 mg/kg of Mn and Cr respectively were recorded.
