Optimization of Sedimentation Tank by CFD

Sudheer Pandia | Dr Bharat Jhamnani ^[2]

Abstract: Sedimentation tank is an important unit in water and wastewater treatment. Sedimentation tank separates the sediments from water and wastewater. The efficiency of sedimentation tank depends upon the dimensions of sedimentation tank, inlet velocity and particle diameter. It is so hard to make different types of sedimentation tank and analyses experimentally. The present study is carried out to optimize the sedimentation tank by using CFD (computational fluid dynamics) and we trace the particle trajectories by using DPM (Discrete Phase Model). The graphs of velocities, pressure drop are analyzed and compared. Efficiency of particle tracing is compared between with or without a baffle wall by varying particle diameter and the number of injected particles.
