The EIMCO-K.C.P Grit Separator is recommended for general application on all sizes ranging up to 60 foot square. Sewage enters uniformly through adjustable deflectors along one side of the square tank and after depositing its grit overflows a at the opposite side, substantially free of grit.

Vortex-Type Grit Chamber The vortex-type grit chamber consists of a cylindrical tank in which the flow enters tangentially, creating a vortex flow pattern. Grit settles by gravity into the bottom of the tank (in a grit hopper) while effluent exits at the top of the tank. The grit that settles into the grit hopper may
