Abstract
Apparatus and methods are provided for controlling influent feed to produce a substantially uniform flow to a clarifier tank () to thereby enhance the settling efficiency within the clarifier. The apparatus comprises a feedwell () having a roof () and continuous sidewall () that together define a feedwell main body enclosure. Influent is fed via a relatively inboard tangential feed mechanism () to the inside of the roof () from an entry point proximate the center of the roof (). Influent energy is properly distributed via the action of centrifugal force to generate a uniform axial flow within the feedwell main body which, in turn, is fed into the clarifier tank. Optional baffle members () may be provided in the housing to slow angular momentum of the influent which, due to its original feed location, would necessarily be at a relatively low level.
