    Abstract: The present invention is a device for separation of particulates with widely different densities from swimming pool waters open to contamination from windblown debris. Vacuum hose cleaning of the bottoms swimming pools requires pre-filtering for leaf, branch, and grass removal before the water passes to the primary filter. The present invention is a low pressure, liquid filled, cylindrical vessel situated vertically wherein the vacuumed mixture of leaves, branches, grass, soil, gravel, and water is introduced tangentially to the interior walls of the cylindrical vessel. An axially located, perforated collection pipe is connected to external piping permitting water draw-off. The tangentially flowing contaminated waters release their leaves, branches, and grass into an annular flowing zone close to the cylindrical vessel walls while heavier soil particles and gravel fall to the floor of the vessel.
