Washing and dewatering must each be as effective as the collection device otherwise the overall system efficiency will suffer. A recent study at a plant showed that while the aerated grit basin removed 58% of total entering grit volume, the cyclone/screw classifier washing and dewatering equipment only retained 17% of what it received.

Grit settles within the lower hopper and is transferred to the washing, classification and dewatering plant by a pumping system. With its sloping sides and specially arranged impeller, the Jeta grit trap provides maximum separation of heavy mineral solids (grit) while rejecting larger and lighter solids, which remain in the water flow.

When designing grit systems, there are two options available for dewatering prior to disposal, either grit "washing" or grit "classification". In simplified terms, you can "wash" the grit to reduce organics (typically <5%), or you can simply "dewater" it and not address the organics (typically <25%).
