- The efficiency of the sedimentation tank indicates the overall percentage removal of suspended matter at a given overflow rate or surface loading rate.
- The efficiency of the sedimentation tank increases if the overflow rate reduces (more time available to particles for settle).
- From the equation, it is clear that if the surface area (B × L) of the tank increases, the overflow rate reduces, and efficiency increases for a given discharge.
Important Points
Efficiency depends on the following parameter during sedimentation:
Efficiency depends on the following parameter during sedimentation:
- The velocity of flow: Efficiency increases if the velocity of flow reduces
- Viscosity: Efficiency increases if viscosity reduces (Viscosity changes but we can not do)
- Size of particle: Efficiency increases if the size of particle increases.

Increasing the surface area of the tank is the correct way to increase the efficiency of a sedimentation tank. Let's break down the explanation:
Increasing the Surface Area of the Tank:
- **Explanation**: By increasing the surface area of the tank, the contact time between the water and the settling particles is increased. This allows for more time for the particles to settle down, leading to improved sedimentation efficiency.
- **Benefits**:
- Enhanced settling of particles: With a larger surface area, the particles have more space to settle, reducing the chances of carryover.
- Improved clarity of effluent: The increased settling time results in clearer water leaving the tank.
- Higher efficiency: Overall, the sedimentation tank operates more effectively with a larger surface area.
- **Methods to Increase Surface Area**:
- Installing baffles or inclined plates: These structures increase the surface area within the tank without increasing the overall dimensions.
- Using multiple smaller tanks: Instead of one large tank, multiple smaller tanks can be used to increase the total surface area available for sedimentation.
