A tank is converted to treat organic waste water from kitchen as shown in the figure below. Biogas gets accumulated on top part of the tank. Which of the following options is a suitable location for drilling an air hole to maintain the water level inside the tank?
A tank is converted to treat organic waste water from kitchen as shown in the figure below. Biogas gets accumulated on top part of the tank. Which of the following options is a suitable location for drilling an air hole to maintain the water level inside the tank?
Show Hint
- A
- B
- C
- D
The Correct Option is C
Solution and Explanation
- An air hole is needed to release accumulated biogas, which otherwise creates pressure and prevents the proper functioning of the system.
Step 2: Determine the correct location for drilling.
- The highest point of the tank is ideal for drilling the air hole since biogas collects at the top. This ensures smooth removal of gas and maintains the water level.
Step 3: Conclude the answer.
The suitable location for the air hole is:\[ {\text{C - At the highest point of the tank}}. \]
