Grit King®

Advanced Hydrodynamic Vortex Separator

Removes up to 15 times more grit than conventional systems.
Product Profile

Applications

The Grit King® is an advanced hydrodynamic vortex separator that
augments gravitational forces to separate grit from water. The
Grit King® is an economical choice for new or existing municipal or
industrial wastewater and water applications.

•t New wastewater treatment plants.

Advantages
•t No moving parts.
•t No external power source.

•t Retrofit to existing treatment works.
•t Grit removal for potable water.
•t Grit removal for sand and gravel extraction plants.
•t Grit removal for industrial effluent.
•t Filter media recovery.

How it works
1.t t low is introduced tangentially to the Grit King® via a
F
tangential inlet creating a rotational flow path around the
outside of the dip plate.
2.t The flow gradually spirals around the perimeter allowing the
grit and sand particles to settle out by gravity (green arrow).
3.t t he grit collects in the grit pot as the centre cone directs
T
flow away from the base and up around the centre shaft into
the inside of the dip plate (blue arrow). The upward flow
rotates at a slower velocity than the outer downward flow.
The resulting ‘shear’ zone scrubs out the finer particles.
4.t t he concentrated grit underflow is pumped or gravity fed to a
T
grit classifier for dewatering (yellow arrow).
5.t t hen used with a Grit Cleanse the result is a clean dewatered
W
grit with very low organic content.
