Study on efficiency of sedimentation tank / Nik Shamsul Bahrim Abdul Latiff

The purpose of this project is to study the efficiencies of sedimentation using a model sedimentation tank at certain flowrates. The sedimentation tank used in this project was the H 310 Mk II Model Sedimentation Tank. The size of the tank is 100cm * 40cm * 20cm. Calcium Carbonate was used as samples in the sedimentation studies. 10% w/w of Calcium Carbonate was obtained and used for the feed tank. The retention time adopted was 30 minutes from which the flowrates were obtained. The values of the flowrates were chosen as one eight, one quarter and half of the calculated flowrates which were 0.33, 0.66 and 1.32 1/mins. For each chosen flowrate, experiment was conducted with and without baffles. The baffle was placed at 50 mm from the inlet weir and 30 mm from the tank top.
