Question

In a biogas plant structure, which component is responsible for mixing waste (dung/slurry) with water before digestion?

Options

• Digester

• Outlet tank

• Inlet tank

• Gas holder/dome

Answer 1

The inlet tank is the component where organic waste such as cattle dung or slurry is mixed with water before being fed into the digester. This mixing ensures proper consistency and distribution of substrate, which is essential for optimal microbial activity during anaerobic digestion. The prepared mixture then flows into the digester for fermentation.
