Answer 1

Wastewater:

1. Wastewater is water that has been used for a variety of human activities and has become contaminated.
2. Many suspended pollutants can be found in wastewater.
3. Water is pumped through a grit and sand removal tank, where sand, grit, pebbles, and other particles settle to the bottom and are removed.
4. Water is then allowed to enter a tank, where sludge (faeces) settles at the bottom and is scraped away.
