Apparatus and method for removal of floatables and scum in a waste water treatment system

摘要

A waste water treatment system includes a clarification tank having a clarification tank wall. An influent feed system (IFS) is mechanically mounted within and adjacent to a wall of the clarification tank and configured to receive a waste water influent stream including a fluid. A scum trough is mechanically coupled to either the IFS or the clarification tank. The scum trough has a scum trough mouth and a scum trough discharge channel. The scum trough is movable, or a portion of the scum trough includes a moveable structure, to control a rate of fluid in-take of the fluid with scum and floatables from either of the IFS or the clarification tank. Several methods to remove scum and floatables from a waste water stream are also described.
