The two-chamber vortex settlement tank 

Usage and Operation

Two-chamber vortex settlement tanks are used to separate and retain suspended particles and grease from wastewater. In the case of suspended particles,  gravitational separation of impurities is supported by centrifugal force caused by the vortex movement in the first chamber. The distribution of grease takes place in the second chamber of the settlement tank as a result of gravitational flotation. Two-chamber vortex settlement tanks  are used mainly to pretreat sewage from urban watersheds and roads where there is a low risk of high levels of pollution from petroleum derivatives.

Construction

Vessel tanks for two-chamber vortex 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 of the first tank there is a drain outlet for sludge free wastewater to enter the second chamber. The second tank acts as a gravity separator and is equipped with a compartment for trapping light pollution. 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, two-chamber vortex settlers can be equipped in residue and grease level sensors.
