The single-chamber vortex settling tank

Usage and Operation

Single-chamber vortex settlers are used for separating and retaining sludge from wastewater. Gravitational separation of impurities is supported by centrifugal force arising from rotational movement in the settling tank. Single-chamber vortex settling tanks are used primarily for treating sewage from urban watersheds and roads, on which there is no risk of petroleum-derived contamination.

 

Construction

One-chamber vortex settling tanks are made of precast concrete, reinforced concrete or plastic.The inlet is inserted tangentially to the wall of the tank or is equipped with a directional deflector forcing rotation.  In the central part there is a bend which drains sludge free wastewater into the outlet chamber from the settling tank.  For the largest devices where the frames are delivered in elements  (B in the type of device), the equipment is assembled on construction site. Optionally, one-chamber vortex settlers can be equipped residue level sensors.
