Rotary distributors are 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. To uniformly
distribute the flow in the thinnest possible sheet over the entire filter area, a
spreader is provided at each orifice.
The proper combination of flow and head requirements determines the general type
of rotary distributor recommended. 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.
Our rotary distributors are furnished for all bed sizes and with center inlet diameters
from 8 inches to 48 inches. Depending on media depth and flow transition requirements,
feed arrangements may be above or beneath the filter floor. 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.
