Vortex settling tank with lamella insert

Usage and Operation

Vortex settlement tanks NIXOR-NOWL are used to separate and retain suspended solids and petroleum-derived substances from sewage.In the case of suspended solids, the gravitational distribution of pollution is supported by the centrifugal force arising from the whirling motion in the first chamber of the settling tank. The wastewater treated from sludge flows into the second chamber where the separation of petroleum derivates from takes place. Due to high cleaning efficiency and relatively small size, vortex settling tanks with lamella, are used primarily for pretreating sewage from urban watersheds and communication nodes.

 

Construction

Vortex settling tanks are made of precast concrete, reinforced concrete or plastic. The first chamber inlet is equipped with a steering directional deflector forcing whirling motion. In the central part of the first tank there is a drain outlet which lets pre-treated sewage into the second chamber. The second tank with the lamella insert acts as a separator. 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, vortex settling tanks with a lamella insert can be equipped with residue and oil level sensors

* Z - designated for the maximum pipe diameter for a given device; individual solutions will be used in the case of depth less than the minimum

B - devices delivered in elements for assembly on the construction site by the ordering party.

NIXOR reserves the right to make design changes without prior notification.

In individual solutions, it is possible to increase the capacity of the settlement tank and grease accumulation.
