Abstract
An inlet structure for dissipating the energy of the influent to a feedwell of a clarifier. The inlet structure has a cylindrical wall centered in the clarifier and closed at the bottom. Ports in the wall are each equipped with a baffle that includes a fixed center vane aligned with the port, a pair of hinged gates on the sides of the center vane, and a bottom baffle underlying the port and the center vane and gates. The gates can be adjusted to control the size and velocity of influent streams that are directed in opposite tangential directions from each port into impingement with streams from adjacent ports for dissipation of the influent energy in the feedwell.
