Abstract
Rotatably supported, regenerative fluid treatment wheel assemblies include a wheel with circumferential rim and track, a housing in which the wheel is disposed and a plurality of rollers disposed within the housing in rolling engagement with the track to locate a wheel axially and radially within the housing. Seal flanges are provided projecting radially outwardly from the rim and are opposed by flexible seals which are clip mounted to walls of the housing surrounding openings through those walls which are aligned with the wheel. At least one wheel is preferably spring loaded so to compensate for any eccentricity in the wheel. The wheel is belt driven. A subassembly, including a mounting plate, flange-mounted motor, drive pulley and spring loaded idler pulley is provided for easy installation and removal. Wear strips appropriate for contact with either the seal flanges or face of the wheel core are applied to the flexible seals by pressure sensitive adhesive. Roller support and location can be applied to hub and spoke wheels as well. Rollers support and location permits the use of a smaller hub and a single bearing, thereby minimizing the center area of the core lost to fluid treatment.
