Abstract
A grit selector having an upper settling chamber and a lower grit storage chamber. The settling chamber communicates with the grit storage chamber through an opening in a transition surface therebetween. An influent flume directs influent liquid directly into a lower portion of the settling chamber. An effluent flume withdraws effluent liquid from an upper portion of the settling chamber. The influent flume and effluent flume have a common centerline with the effluent flume being positioned at an elevation above the influent flume. A baffle member extends into the settling chamber for directing the influent liquid stream outwardly towards a lower portion of the periphery of the settling chamber.
