ABSTRACT:
An integrated system for diverting and reducing the size of waste materials in an effluent stream comprising a frame having a bottom housing and a top housing and mountable in the stream. A grinder unit is mounted to the frame bottom housing and comprises a cutter assembly positioned in the stream and a drive mechanism coupled to the cutter assembly to rotate the cutter assembly. The drive mechanism may be electric or hydraulic. A screen unit is mounted to the frame. It may be a single screen or dual screens. The screen unit comprises a cylindrical screen rotating on a screen shaft having a screen shaft mounted on bottom housing of the frame and supporting the cylindrical screen. A drive assembly operably couples the drive mechanism to the screen shaft to rotate the cylindrical screen as the cutter assembly rotates. In operation with the screen unit positioned adjacent to the grinder unit it diverts solids in the effluent stream toward the grinder unit for size reduction. An auger-screen may be placed downstream for removal of large solids after size reduction.
