How To Remove Sand From Well Water With a Centrifugal Sand Separator
In a centrifugal sand separator, the water rushes through the device and the centrifugal forces sling large particles, sand, debris, and sludge outward to the separator wall and downward in a spiral motion. Gravitational force pulls the separated solid particles downward past the spin trap plate into the solids holding chamber.
