ABSTRACT

Nowadays, the destruction and pollution of humane environment has produced an ever growing awareness worldwide of the need for more effective sedimentation processes. The main aim of this project was to design and fabricate an experimental sedimentation rig with the objective to determine the rate of settling against time using calcium carbonate as a test sample.The rig consists mainly of the cylindrical tank, valves, motor, stirrer, and the sight glass. For the test run, 82 litres of water and500g of calcium carbonate was introduced into the tank,stirred andwas let tosettle under gravity. The settled height was observed with time at time intervals of 60 seconds,it could be observed that the calcium carbonate settles at different height of 115, 110.5, 104.6, 99.3, 92.5, 85.7, 77.5, 68.3, 60.1, 52.5, 42.3, 33.4, 20.6 and 10.8cm considering the settling behavior. The settling velocity and Reynolds number of flow gotten was 15.42cm/min and 84.5respectively. It could be concluded from the experiment conducted with the rig thatthe higher the concentration is the quicker the sedimentation process is done quickly and the rig could be recommended for waste water industries to study rate of settings of sediments of different particulate distribution from fluids.
