Circular tanks have long been used for sedimentation purposes in connection with industrial processes, waste control, water, and sewage treatment. In the design of such tanks, stress has been laid on obtaining the proper detention time for suitable removal of the suspended matter. Little attention has been paid to the hydraulics of the inlet, with a consequent loss in tank efficiency. By means of a model, various inlets were observed and a new type inlet developed appearing to have improved hydraulic characteristics which will increase solid removals now being obtained with accepted types of inlets.
