What is sludge? Explain how it is treated?

Answer :

Semi-solid wastes like feces that settle down at the bottom during wastewater treatment are called sludge.

The sludge is removed using a scrapper and then transferred to a separate tank where it is decomposed by the anaerobic bacteria to produce biogas.

This biogas is used as fuel for cooking, heating, etc.
