An influent feed system to classify and separate particulate matter and solvated materials from an influent stream includes one or more influent feed troughs in fluid communication with a clarification tank. One or more grit boxes are in fluid communication with the one or more influent feed troughs. The one or more grit boxes include a hopper (506) for accumulation of materials to be deposited. The hopper (506) has a drainage pipe (570) and a valve (580) that controls communication of materials between the influent feed system and the drainage pipe. A mechanism delivers the influent stream at a predetermined and a substantially constant flow rate. The influent stream is separated into two or more streams and recombined under pressure in the grit boxes. A grit box to classify and separate particulate matter and solvated materials from an influent stream is also described. |
