The Motion and Removal Efficiency of Particles in Circular Tube Settlers

摘要

Based on the assumption that flow pattern in tube settlers is laminar and the distribution of flow velocity is a circumgyratetional paraboloid, general hydraulic equations are deduced, with consideration of the effectors of acceleration and initial fall velocity of setting particles, and length , counting radius , and obliquity of circular settling tubers. Comparison with other equations presented by other researchers indicates a good agreement. A deduced removal efficiency formula for tube settlers with consideration of particle distribution could be calculated by software of matlab.
