Hybrid Design Rake

The Hybrid Design Rake is appropriate for applications in which it is desirable to use a suction pipe clarifier, but which feature a low solids level at the periphery of the clarifier.

The addition of spiral blades at the end of the rake allows the collection of the relatively few solids to a point where they can be concentrated and removed by the suction pipe.

This greatly reduces the amount of clean water which is returned with the sludge. In the event of an upset, several suction pipes are concentrated at the peak sludge collection area of the spiral blade so that unexpected heavy solids loads can be dealt with no upset to the effluent quality.
