Grit Handling/Removal/Hauling

WEMCO Pumps Hydrogritter

The WEMCO Pumps Hydrogritter is a grit classifier system that removes 95% of particles of 105 micron/150 mesh with a specific gravity of 2.65 and greater. The unit’s main purpose is to protect downstream equipment from damage due to abrasive wear. A cyclone concentrates the grit slurry to approximately a 10-1 ratio. After the grit is concentrated, it drops into a settling pool, specifically sized for removing fine grit. When in the pool, the grit particles settle, while the lighter particles, such as organics, float and are carried over the weir at the end of the pool, to be returned to the wastewater stream. The settled grit is then carried up the inclined bottom of the unit to the discharge chute, where it is dropped into a dumpster for final disposal. 801-359-8731;
