Question
Explain how organic matter is separated from sewage?
✓
Answer
Organic matter is separated from sewage by allowing it to settle in large tanks called sedimentation tanks or primary settling tanks.
In these tanks, the heavier solid particles (organic matter) settle at the bottom as sludge.
The lighter liquid on top, called supernatant, moves on for further treatment.
