​Hydrocyclones, otherwise referred to as cyclones, are mechanical separation devices that utilize centripetal or centrifugal forces within a vortex in order to sort particles present within a liquid suspension.

Hydrocyclones Benefits:

  • Compact and simple structure
  • No moving parts
  • Low investment and running cost
  • Easy to install and simple to operate
  • High efficiency
  • High erosion resistance
  • Process high volumes
  • Small footprint

When feed slurry enters the hydrocyclone under pressure that creates high centrifugal forces, particles coarser than the “cut point” size migrate into a primary vortex adjacent to the wall and move forward to discharge with a small volume of water via the spigot.

Particles finer than the “cut point” size migrate into a secondary upward-moving vortex, along the axis of the hydrocyclone and discharge with the majority of the water.

Hydrocyclones are limited in being able to dewater fine solids to a conveyable state Dewatering Screens are used to further dewater Hydrocyclone underflow.

Slurry Hydrocyclones
Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be.

Dewatering and Solids Separation

Dewatering EPA

Solids Separation Systems

Dewatering and separating solids in tight confines and those who require a faster dewatering and separation solution, we build out an integrated system to fit your space requirements.

Decanter Centrifuge Slurry

Decanting Centrifuges

This offers you the opportunity to dewater to a greater level your slurry and make a cake that is easier to transport and less costly to dispose of.

Dredging Dewatering Consulting

Geotextile Tubes

Cost effective, simple to use and well known this is a great for those who want to dewater their dredge on site and optionally leave it for barrirr protection or haul it away.

Slurry enters the feed inlet at a designated pressure and volume. Independent of the shape or configuration of the inlet, slurry follows the fall of the upper cylinder in a rotating action. Resultant centrifugal forces send coarser material to the outer wall to travel downward and be further accelerated in the conical sections. These coarser fractions then exit through the apex, or spigot, at the bottom of the Hydrocyclone. Finer fractions remain rotating with the fluid in the inner core and are removed upward by an air core.


Remove solids from your slurry stream with the simple physics of Hydrocyclones.  This is a high speed option to separate your water from solids.

Shale Shakers and Shaker Screens

Immediately remove large solids and dewater from your slurry stream as part of your separation process.

Dewatering Tank Systems

Essentially a geotextile tube in a container this option is great for emergency projects and city dewatering where space and the ability to truck the system away is important.
