Impact of bubble coalescence on separation performance

25/09/2015  The small bubble separation efficiency of a hydrocyclone is the key variable that is considered in degassing and it is commonly believed that the degassing process in a hydrocyclone will not be performed well due to the lack of bubble force and residence time. To date, however, these issues have not been addressed by the above-mentioned simulation models or research efforts, which are ...

Hydrocyclone - Wikipedia

A hydrocyclone (often referred to by the shortened form hydroclone or cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles. Hydrocyclones also find application in the separation of liquids of different densities.

Cavex® Hydrocyclones Weir Group

Hydrocyclones, also known simply as ‘cyclones’, are a classification device that uses centrifugal force to selectively concentrate slurry particles through a separation process. This simple process separates the slurry mixture, with the larger mass particles leaving through the hydrocyclone underflow and the water and fines exiting through the overflow.
