Rotary Distributors

The EIMCO-K.C.P Rotary Distributor is used for the uniform distribution of screened and/or clarified wastewater over the surface of a biological filter media. Flow is introduced at the center of the unit and is distributed by means of two or more rotating arms with orifices and spreaders. Hydraulic power created by the reaction of the jet-like streams escaping from the orifices is sufficient to rotate the machine. A spreader is provided at each orifice to uniformly distribute the flow in the thinnest possible sheet over the entire filter area.

The general type of rotary distributor recommended is determined by the proper combination of flow and head requirements. Center assembly designs are suitable for standard or high rate applications, with or without flow control features. Distributor arms are of circular pipe construction or may be fabricated from steel plate with single or multiple compartments.

The EIMCO-K.C.P Rotary Distributors are furnished for all bed sizes and with center inlet diameters from 8 in. to 54 in. Feed arrangements may be above or beneath the filter floor depending on media depth and flow transition requirements. The height of the center well is varied according to the head required and support for the distributor arms is provided by either tie rods or trusses.
