Walker - Rotary Distributors - Brochure

Mast Type: Type M RotoSeal rotary distributors distribute wastewater over trickling filter rock or media to ensure uniform filter loading. Inlet water is introduced at the mast or center column and flows out to either 2 or 4 distributor arms through a sealed manifold. The arms are fitted with field-adjustable orifices and spreaders and the mechanism rotation is driven by the hydraulic force of the flow. The Type M is applicable to filter diameters up to 175 feet and nominal flow rates up to 5,000 GPM.
