Sewage treatment is a crucial process that removes contaminants from wastewater, household sewage, and effluents. It involves physical, chemical, and biological methods to ensure that the treated water is safe for disposal or reuse. Proper sewage treatment helps protect the environment and reduces the demand for portable water in buildings. Stages of Sewage Treatment Sewage treatment typically involves three main stages: primary, secondary, and tertiary treatment. 1. Primary Treatment (Solid Separation) Large solid particles and sediments are separated from the wastewater. The solids settle at the bottom, while lighter materials like oils and grease float and are removed. 2. Secondary Treatment (Biological Process) The remaining wastewater contains dissolved organic matter. This is broken down using water-borne microorganisms that convert waste into a solid mass. The biological solids are then neutralized and either disposed of or reused. 3. Tertiary Treatment (Final Purification &...
