Rotary Distributors

Rotary Distributors
Walker Process Equipment offers two types of rotary distributors. Type M RotoSeal rotary distributors are applied to uniformly distribute wastewater over trickling filter rock or media to ensure uniform filter loading. Flow is introduced at the mast or center column and manifolded to the arms which are fitted with orifices and spreaders. Type MT RotoSeal rotary distributors are for higher flowrates or larger filter diameters requiring greater bearing capacity than is available with Type M rotary distributors.
