Claro is pleased to offer a high-quality grit washer that washes & dewaters sediment extracted from various types of grit collection equipment including sewage treatment plant aerated grit chambers & forced vortex sand trap units. Used also for recovery of treatment process sands.

Vibration & water jets thoroughly wash organics off of the collected grit & sand. Resultant grit meets the highest material reuse standards. After cleaning by the grit washer, the grit material is transported by a special abrasion-resistant micro alloy shaftless grit spiral to a container or downstream handling equipment. The separated organic matter & wastewater is reintroduced into the plant flow stream. Dry solids content of washed sand/grit reaches up to >90% DS. Effective grit washing, totally enclosed operation, & optional hygienic bagger delivers additional odor control & hygienic operation.
