Abstract: The grit removal efficiency of a hydrocyclone desander is greatly improved by providing a curved plate within the separation chamber, positioned along one side of the chamber such that the incoming fluid stream is directed toward the concave surface of the curved plate. The curvature of the plate is a circular arc, preferably about a quarter circle.
