<p>A dynamic sedimentation system comprises inlet pipe 6 through which raw turbid water enters inlet facility 1, to fill compartment 3 thus priming siphon pipe 7 and filling sedimentation tank 2 of circular plan-form until full, entering said tank tangentially at its perimeter, imparting rotational motion to its contained water about a vertical axis through its center, and lowering water level in compartment 3, whereupon pipe 7 becomes unprimed halting inflow to tank 2 and slowing rotation of water through friction until nearly stationary, thereby causing suspended solids to migrate towards the center of tank 2 and settle, while clear water above is drawn off through float supported pipe end 14, and conveyed to clear water storage reservoir 4 and supply, and remaining sediment laden water in tank 2 is automatically drained for disposal by waste pipe 29 through valve 28 at the bottom of the tank.</p> |
