Wastewater treatment process: a modified model for oxidation pond

Wastewater treatment aims to eliminate suspended solids as many as possible before the remaining water, known as effluent, is released into the environment. Oxidation pond methods have practically been proven successful for the wastewater treatment process due to their low construction and maintenan...
