Primary Treatment:
Primary treatment is the first step in the sewage treatment process, which involves the physical removal of large solids and debris from the wastewater.

Removal of Suspended Solids:
- Primary treatment mainly focuses on removing suspended solids through processes such as screening, settling, and sedimentation.
- In the primary treatment process, wastewater flows through screens to remove large objects and then enters a sedimentation tank where heavier particles settle at the bottom.
- The settled solids, also known as sludge, are then removed from the tank, leaving behind partially clarified wastewater.

Importance of Removing Suspended Solids:
- Removing suspended solids is crucial as they can clog pipes, pumps, and other equipment in the treatment plant.
- Additionally, suspended solids can carry pollutants and pathogens, which need to be removed to protect the environment and public health.

Conclusion:
In conclusion, primary treatment plays a vital role in sewage treatment by effectively removing suspended solids from the wastewater before it undergoes further treatment processes. This step helps in improving the overall efficiency of the treatment plant and ensuring the quality of the treated effluent.
