Such sweepers systems are specifically engineered for each sump or basin and are designed to continuously circulate and direct the fluid stream toward the suction of the pump, preventing solids from settling to the bottom of the sump/basin. Model selection is based on the recirculation flow rate of the cooling tower and/or size of the cooling tower in tons. sand filter + sand filter systems Griswold Water Systems’ Sand Filters are designed as self contained units for your filtration needs.
