Settling rate of clay and silt particles in a baffled sedimentation / Nur Zaidani Wati Mohd Darwis

Sediment can be classified as deposited or suspended. High suspended materials naturally present in water bodies or present by human activities has decrease the quality of water. Removing suspended materials by sedimentation process using sedimentation tanks is commonly practiced. However, not mu...

The reduction of concentration in baffled tank, were 74.66%, 78.79%, 81.96% and 85.41% with average of 80.21%, while reduction in tank without baffles were 54.52%, 64.36%, 70.32% and 76.14% with average of 66.34%.
