**Step-by-Step Solution:** 1. **Understanding Sewage Treatment**: Sewage treatment is a process used by municipal corporations to purify sewage water before it is released into the environment. This process typically involves two main stages: primary treatment and secondary treatment. 2. **Primary Treatment**: The primary treatment of sewage involves physical methods to remove impurities. This includes processes like filtration and sedimentation. 3. **Filtration Process**: In the filtration stage, visible impurities and solid waste are removed from the sewage water. This can be done using nets or manually to ensure that larger particles are eliminated. ...
