This process involves various physical, chemical, and biological methods to treat and purify the wastewater before it is discharged back into the environment. The aim of sewage treatment is to protect public health and the environment by reducing the levels of pollutants, such as bacteria, viruses, organic matter, and nutrients, in the wastewater. Common treatment methods include screening, grit removal, sedimentation, biological treatment (such as activated sludge and trickling filters), and disinfection. The treated wastewater, known as effluent, may then be reused for various purposes or discharged into receiving bodies of water. Sewage treatment plays a critical role in maintaining sanitation and preventing water pollution, thus ensuring a safe and healthy environment for communities.
