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 result from turbidity measurement showed that percentage reduction of turbidity in a baffled sedimentation tank were higher than in tank without baffles, which were 84.34%, 79.89%, 82.21% and 75.40% with average of 80.46% compared to 26.29%, 41.64%, 47.84% and 47.30% with average of 40.77%.
