Introduction One of the most frequent oversight areas in wastewater treatment plant (WWTP) design is the “last mile” of the solids handling process: moving dewatered cake from the centrifuge, belt press, or screw press to its final load-out point. Engineers often spend months optimizing the dewatering device itself, only to treat the conveyance system as […]

INTRODUCTION Grit removal efficiency is often the silent variable that dictates the lifespan of downstream biosolids equipment, clarifier drives, and digesters. While the civil design of grit chambers (vortex vs. detritor vs. aerated) garners significant attention during the design phase, the mechanism for extracting that captured grit—the grit pump—is the common failure point. Engineers often […]
