ACE Gritter is a grit de-waterer designed to receive grit pumped in suspension from the main process stream.

Operation

Flow enters the main reception chamber where grit is allowed to settle while the main stream flows over side weirs and is returned to the process stream.

A scraper arm deposits the grit into a discharge chute when the grit pumps stops delivering.

Liquid drains out of the grit bulk back to the flow, allowing grit to be collected and processed in a dewatered state.
