- Standard Efficiency Grit Vortex System

From

0

Using a combination of inlet feed stream energy and auxiliary water jet energy, the Fluidyne Hydro-Grit vortex grit separation system is unique in design and the benefits provided, yet the principles of its operation are well-proven. Grit and other heavy particles are separated, washed and removed from liquid streams effectively and efficiently. The Hydro-Grit™ system is all-hydraulic, non-mechanical and non-clogging.

FORCED VORTEX AND GRAVITY WORKING TOGETHER

The Hydro-Grit™ system takes maximum advantage of the principle of sub-cyclonic separation without the need for any moving parts resulting in removal of grit particles as small as 0.2 MM. Special application design is available which provides for the removal of even finer particles.

SIMPLE AND EFFICIENT

In the Hydro-Grit™ system, the forced fluid vortex, with the assistance of gravity, causes grit to fall to the chamber floor. The sloped shoulder of the grit chamber maximizes the effect of the active vortex and gravity acting on the grit particles while eliminating accumulation. Here, the AirCirc™ unit acts to pick up the lighter organic particles while the grit particles settle to the collection hopper.

PERFECT FOR VARIABLE FEED STREAM FLOW RATES

The Fluidyne AirCirc™ circulating jet, featured in the Hydro-Grit™ system, provides effective sub-cyclonic grit separation action irrespective of the feed stream flow rate or volume. This makes it ideal for domestic wastewater treatment and similar applications.

MATCHED TO YOUR OPERATION

Given that the influent flow in typical wastewater treatment plants is highly variable, the Hydro-Grit™ system is designed so it can be matched in size to peak flow rate in order to provide optimum results. Because of the unique Fluidyne AirCirc™ - jet circulator, full-range performance is possible, from zero to peak flow. Depending on peak flow conditions, the Hydro-Grit™ system can be installed in multiple tanks if required.
