Question

Which of the following is NOT listed as a component of a typical biogas plant structure?

विकल्प

• Cooling tower

• Gas holder/dome

• Digester

• Inlet tank

Answer 1

A typical biogas plant consists of four main components: inlet tank (for mixing waste with water), digester (underground airtight tank for fermentation), gas holder/dome (for collecting and storing biogas), and outlet tank (for removal of spent slurry). A cooling tower is not part of the standard biogas plant structure. While temperature management is important for optimal methanogen activity, cooling towers are not employed in traditional small-scale rural biogas installations.
