Use of a Swirl Concentrator for Combined Sewer Overflow

The swirl concentrator, which induces a swirl action in a liquid for solids separation, was recommended because of its ability to allow much higher flow rates for a given surface area and tank volume than those characteristic of more conventional settling tanks. The clarified effluent from the concentrator is discharged into the stream. Floating solids are collected by a scum ring and the

Swirl concentrator civil engineering Britannica

In wastewater treatment: Combined systems sewage involves the use of swirl concentrators. These direct sewage through cylindrically shaped devices that create a vortex, or whirlpool, effect. The vortex helps concentrate impurities in a much smaller volume of water for treatment.

Swirl Concentrator as a Grit Separator Device

The swirl concentrator principle involves the development of a flow chamber utilizing "circular, long-path kinetic energy to produce separation of solids from liquid and settling of the particles. The settling is achieved by the development of optimum hydraulic conditions to accomplish settling ..• removal of solids without the use of mechanical accessories. A limited number of tests were

Swirl Concentrator for Erosion Runoff Treatment

The swirl concentrator as an erosion control device has been designed to concentrate the heavier soils from large flows. The concentrated underflow of up to 14 percent of the flow can be directed to a forebay or settling basin. The device is circular and for small watersheds a simple stock watering tank could be used with only minor modifications.

In-orbit performance of the SAX Low-Energy Concentrator

The low energy concentrator system (LECS) is an imaging x- ray spectrometer. I is one of the narrow field instruments onboard the SAX satellite and covers the energy range from 0.1 to 10 keV. The good low energy response of the detector is achieved by using a driftless gas cell and a thin multilayer polyimide foil as an entrance window. SAX was launched on April 30, 1996.

Concentrator photovoltaics Wikipedia

Concentrator photovoltaics (CPV) (also known as concentration photovoltaics) is a photovoltaic technology that generates electricity from sunlight. Unlike conventional photovoltaic systems, it uses lenses or curved mirrors to focus sunlight onto small, highly efficient, multi-junction (MJ) solar cells.In addition, CPV systems often use solar trackers and sometimes a cooling system to further
