Vortex Grit Separator
Vortex Grit Separator
Model VDG | Submerged Thruster
PRODUCT RESOURCE MATERIALS
The Model VDG is the most straightforward and economical grit removal system in the market today. GRIT-GUARD creates a powerful vortex, even at a lower flow rate, resulting in an accelerated grit separation.
The GRIT-GUARD is powered by submerged thrusters; a simple, low cost means to delivers optimal vortex flow. The dynamic thruster is engineered with a lifting assembly for manual positioning to produce customized flow directions and velocity. For deeper tanks, multiple thrusters can be strategically arranged to optimize vortex distribution without major cost implications.
GRIT-GUARD Model VDG components apply to tank sizes from 72” to 240". There are no mechanical drives, cross-tanks, support structures or parts to maintain and lubricate. The tank is cylindrical with tangential inlet and a tapered, conical, grit-collection bottom. Collected grit is removed by airlift or centrifugal grit pump.
Unique Vortex Degritter design using simple, low cost submerged PEI PRO-MIX propeller thruster to maintain vortex flow
Applies to most vortex degritter tank designs
Wall mounted thruster is easily retrievable for adjustment or maintenance
Variable thruster orientation to optimize performance
OPERATION PRINCIPLES
The GRIT-GUARD Vortex Grit Separator utilizes a forced vortex to accelerate grit separation and accumulate grit at the tank bottom for removal. In the cylindrical tank, a submerged thruster is positioned to facilitate the vortex flow while a pump lifts the separated grit to the next GRIT-GUARD washing / classifying process.
