Assessing behavior and fate of micropollutants during wastewater treatment: Statistical analysis

Abstract

This study examines the occurrence of micropollutants (n = 46) in raw sewage, as well as the fate of the removal performance for these substances by the Al-Hoceima city wastewater treatment plant. The treatment process removed more than 50-90% of heavy metals from the wastewater. Polycyclic Aromatic Hydrocarbons and Polychlorinated Biphenyls were eliminated from wastewater by 20-50%. The quality of the effluent discharged complied with national and international wastewater discharge standards. Statistical methods were applied to examine the relationships between the concentrations of micropollutants and macropollutants entering and leaving the wastewater treatment plant, and a model for estimating the production of micropollutants, based on a measurement of macro pollution parameters.
