ROTARY DISTRIBUTORS are used for biological growth extraction from domestic waste water prior to final clarification. The waste water is pumped to a rotary distributor for spreading uniformly over the filter surface. Rotary arms are driven by the reaction of the waste water flowing out of the distributor nozzle spreaders. Bed underdrains carry away the effluent and permit the circulation of air needed for biological growth. The rotary distributor utilizes top and middle anti-friction roller bearings assuring minimum friction during operation. 

Available in sizes 0 - 200 ft diameter.
