Webb14 maj 1999 · Two earlier proposed methods are applied to the calculation of the settling velocity of a solid particle, including the effect of solid particle concentration within the suspending fluid. The most appropriate method for slurry transportation among these two methods is discussed and used in the analysis of critical flow velocity. Webbhopper. Grit slurry is pumped by dedicated grit slurry pumps from the storage hopper to the grit handling equipment for further processing. Detritus Tanks Detritus grit removal tanks are constant liquid level, short detention time settling chambers. They are typically square in shape and relatively shallow, approximately 18 to 36 inches deep.
