Evoqua's VAF [TM] brand 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 fluid it is in. The more significant the difference in gravity between the water and the particle, the greater the efficiency of ...
hydrocyclone did not provide any conclusive data as to whether polymer addition with the use of a hydrocyclone was more effective than polymer-only addition. Nutrient profiles from UB did not provide any change in NH4-N, NO3-N, NO2-N, or PO4-P, with the hydrocyclone being operational or not on the secondary clarifier effluent.

The hydrocyclone is the equipment for separating different sizes of particles by the principle of centrifugal precipitation [].Due to its simple structure, easy operation, large handling capacity, and low cost of repair, the hydrocyclone is extensively applied in coal, chemical, petroleum, and other industries [2, 3].The separation performance of …
1. Pressure at the inlet of the Hydrocyclone can tell you a lot. Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be. The separation point is the size at which a particle has a 50-50 chance of reporting either to the underflow or overflow.
Design of the hydrocyclone. In this study, the Stairmand high-efficiency cyclone created by Stairmand was used as a reference for the design, while considering ways to improve the separation efficiency to design a high performance hydrocyclone that could operate at an ultra-low flow rate of 1 L/min (Stairmand, 1951 ).

Hydrocyclone G with an SC of 2.5 wt % provided the best classification performance (C f = 0.89 and C c = 0.99). With the increase in feed SC, the general separation performance of all hydrocyclones decreased, but the arc inlet hydrocyclones still exhibited relatively better performance than the tangential ones. If a higher feed SC is …
The gas moves toward the center of the hydrocyclone with the oil and exits the unit through the reject port. A small amount of gas can improve performance, but too much gas disrupts the smooth flow of the oil core and bottlenecks the flow of oil out of the reject, Walsh said. Important trade-offs must be considered when designing a …
