Particle Separation





Hydro cyclonic, Centrifugal Separation or Particle Separators are all essentially terms used for a filtration method for reduction of total suspended solids in fluid.  The principle technology typically uses a conical shaped separator that accelerates the velocity of water maximizing separation of sand and other solid matter with greater than 90% efficiency.  Hydro cyclonic Separators are not true filters. (Having no physical barrier to stop certain size particles from the water stream.)

Based on the centrifuge principle, the particles are spun against the outside wall of the Hydro cyclone and gravitate towards the bottom into the drain while clean liquid moves upward to the center of the spiral, towards the top outlet. The velocity at which the water flows through the Hydro cyclone determines the efficiency at which the particles are separated from the water.

Hydro cyclone Separation Efficiency

The separation efficiency of a Hydro cyclone under a particular set of running conditions can be described in terms of the "heavies" concentration in the "lights" outflow as a percentage of the "heavies" loading in the total inflow.


For example:

"Heavies" loading in inflow = 2.4%
"Heavies" loading in "lights" outflow = 0.2%

Separation efficiency = 100% x (2.4 - 0.2) / 2.4 = 91.7%


Volumetric percentage separation calculations (%v/v) are usually quicker and easier to perform. However, the separation efficiency calculation can also be performed on a mass basis (%w/w). 


Changes in hydro cyclone operating conditions can lead to significant changes in separation efficiency. Some of the running conditions that can affect separation efficiency are:

Inflow "heavies" concentration

Inflow rate

Outflow ratio ("heavies" flow vs. "lights" flow)



Other bulk liquid characteristics

NOTE: The Particle Size Separation chart is based on sand with a specific gravity of 2.7 gr./cm.




Find your system flow rate and move vertically up the chart until you intersect within the recommended range. This indicates a particular hydrocyclone size. If the flow rate does not intersect within the recommended range, Con-Serv Manufacturing designs include two smaller units in combination. If material to be removed is extremely fine, we use a higher headloss and/or multiple hydrocyclone units of a smaller size. A smaller hydrocyclone can remove finer particles than one with a larger diameter.
