The Grit Snail uses a slow moving cleated belt to gently escalate grit from the clarifier pool without re-suspending fine grit particles which will cause them to escape with the clarifier overflow.

The clarifier is sized to provide sufficient area for particles as small as 75 micron to settle. The captured grit settles to the bottom of the clarifier and onto the belt. The slowly moving belt gently lifts accumulated grit from the clarifier bottom without re-suspending it, eliminating the potential for fine grit to wash out the effluent connection.
