Hydrocyclone Centrifugal Separators Evoqua

Hydrocyclone Separators are effective in removing suspended particles from any flow stream of water where the specific gravity (density) of the particle(s) is heavier than the water it is in; the more significant the difference in the gravity between the water and the particle, the greater the efficiency of the removal process.

An Introduction to Basic Hydrocyclone Operation

An Introduction to Basic Hydrocyclone Operation What is a Cyclone ? A cyclone is a piece of process equipment capable of handling large volumes of slurry and classifying it based on differences in size and/or specific gravity. Based on these differences a cyclone will then produce two products an underflow and an overflow.

The behavior of suspended particles in water is determined by the specific gravity of the particles. Specific gravity is defined as the ratio of the density of a wet particle to that of water (APHA, 1989). Fish feces is not much "heavier" than water and therefore does not settle as rapidly as would aggregate material of the same size.
