Inclined Plate Settlers to Treat Storm-Water Solids

摘要: Many pollutants in storm-water runoff associate with the particulate fraction, as well cause receiving water degradation themselves. Therefore, removing a substantial amount of solids (such all particles above critical particle size) can reduce concentrations many pollutants. Enhanced sedimentation methods have been encouraged to footprint treatment devices and meet 80% suspended reduction goal established locations. Inclined plates/tube settlers, where overlapping plates result large settling areas small device footprints, treated multiple contaminants when operated laminar flow conditions (Pitt et al. 1999). This project extends that work by investigating potential inclined plate settlers treat Reynolds numbers ranged from 7.5 50,000. These achieved high removals for density sand over range Reynolds’ numbers. The influent-to-effluent median particle-size field testing w...
