2. Primary Treatment:
   In this stage, wastewater flows into primary clarifiers, where the physical process of sedimentation removes settled solids, commonly referred to as sludge. The sludge is subsequently transported to digesters where it undergoes anaerobic digestion to reduce volume and stabilize organic content.

3. Secondary Treatment:
   During secondary treatment, biological processes are used to further reduce the presence of dissolved and suspended organic matter. This is typically achieved through the use of aeration basins where microorganisms consume organic pollutants, after which the mixture moves to secondary clarifiers for additional sedimentation.

4. Tertiary Treatment:
   The final stage of treatment includes advanced filtration and disinfection to remove any remaining impurities and pathogens. This ensures that the treated effluent released into the environment is safe and meets all regulatory requirements.
