SlurryCup™ is a grit washing system that uses two levels of separation and classification to capture, wash and classify grit as small as 75μm from grit slurries, primary and secondary sludge, protecting downstream processes from abrasive wear and clogging.

The SlurryCup™ is extremely effective at washing grit captured at the preliminary treatment stage by the grit channel, aerated grit chamber, vortex grit collector, or grit separator. The clean grit slurry produced by the SlurryCup™, when dewatered by a Grit Snail®, contains 60% total solids with less than 15% organic solids in headworks applications, reducing the cost of solids handling and haulage to solid waste disposal sites, as well as reducing odours and associated aesthetic complaints.
