1. Primary Treatment: This is the first stage of wastewater treatment and includes the removal of large objects such as plastic, wood, cloth, trash, and other debris from the wastewater.
2. Secondary Treatment: This stage involves biological processes to break down organic matter in the wastewater. It usually involves the use of activated sludge, an aeration process, and a sedimentation basin.
3. Tertiary Treatment: This treatment stage is designed to remove more pollutants from the wastewater before it is discharged back into the environment. Common techniques used in tertiary treatment include filtration, chemical precipitation, disinfection, and advanced oxidation processes.
4. Sludge Treatment and Disposal: This stage involves processing the sludge left over from the treatment process. Sludge is treated and disposed of either through land application, incineration, composting, or anaerobic digestion.
