Question

Explain how sludge it is treated ?

Answer 1

Sludge can be treated by making biogas plant in which in one hole we put the sludge and which goes into digestor where presence of oxygen is absent so anaerobic bacterias are formed and decomposes the sludge and during decomposition certain gases are formed which comes out through the other side by a hole and can be used as biogas.


hope it helps.

Answer 2

Answer:

Semi-solids such as faeces that settle down during wastewater treatment are called sludge. This sludge is removed using a scraper and then transferred to a tank where it is decomposed by anaerobic bacteria to produce biogas. This biogas is used as a low-cost fuel for heating, cooking, etc. It is also used to produce electricity.
