Secondary Treatment

After primary treatment, the sewage undergoes secondary treatment, which involves biological processes to break down organic matter. This is typically achieved through the use of microorganisms that consume and decompose organic pollutants. One common method is the activated sludge process, where sewage is mixed with a small amount of sludge loaded with bacteria. The mixture is aerated to encourage bacterial growth and activity. The bacteria consume the organic matter, and the treated water is then separated from the sludge. This step significantly reduces the levels of organic pollutants and nutrients in the wastewater.

Tertiary Treatment

Tertiary treatment is the final stage of sewage treatment and involves additional purification steps to ensure the treated water meets safety standards. This can include various processes such as filtration, where remaining solids and fine particles are removed, and disinfection, where harmful pathogens are eliminated. Common disinfection methods include chlorination, ultraviolet (UV) light, and ozone treatment. In some cases, advanced methods like membrane filtration or reverse osmosis are used to remove dissolved substances and contaminants, ensuring the treated water is of high quality.

Disposal or Reuse

Once the sewage has been thoroughly treated, it must be either disposed of or reused in a safe and environmentally friendly manner. Treated sewage, often referred to as effluent, is commonly discharged into natural water bodies like rivers, lakes, or oceans, where it undergoes further natural purification. However, increasing emphasis is being placed on the reuse of treated sewage, particularly in regions facing water scarcity. Treated effluent can be reused for various purposes such as agricultural irrigation, landscape watering, industrial processes, and even as a source of drinking water after further purification.
