The Principle Of Particle Settling In Motionless Fluid

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 gra…
