| Description: | Water treatment plants (STPs) play a crucial role in treating and purifying polluted water before it is discharged into the environment. Various processes such as filtration, sedimentation, and biological filtration are used to remove contaminants and make the water suitable for reuse or safe discharge. The efficiency of these plants depends on several factors, including the technology used, the quality of incoming water, and proper facility management. Effective design and operation of these plants are necessary to maintain water quality and protect the environment. This research aims to analyze the physical, chemical parameters to study the environmental impact and efficiency of sewage treatment in treatment plants in the Mila region. Laboratory analyses were carried out at these stations between January 2023 and March 2024, based on raw water and treated water. These analyses aimed to evaluate the different physicochemical characteristics of the water before and after treatment. The objective was to measure the effectiveness of the purification processes and determine the quality of the treated water compared to the initial raw water, with data covering the period from January 2023 to March 2024, collected from relevant authorities, including the National Sanitation Agency (ONA) and sewage treatment plants (STPs). The analysis of the results for this period shows that all plants exhibit high levels of treatment efficiency: the efficiency of suspended solids removal ranges from 92% to 97%, biochemical oxygen demand (BOD5) efficiency ranges from 96% to 97%, and chemical oxygen demand (COD) efficiency reaches 94%. In contrast, the efficiency of orthophosphate removal ranges from 39% to 74%, and nitrate removal from 44% to 54%. Variations in the removal of different pollutants indicate loads for suspended solids up to 50,450 kg/day, for nitrates 558 kg/day, and for orthophosphate up to 762 kg/day. |
