Abstract:
A method for cleaning rotating filter media by pressurized spray, comprising the steps of:providing at least one spray arm having a plurality of adjacent spray nozzles spaced along said spray arm, each of said nozzles producing an elliptical spray contact area on said filter media, said contact area having a major axis and a minor axis, said major axes having an orientation with respect to said spray arm; affixing said plurality of spray nozzles on said at least one spray arm such that the spacing between nozzles is non-uniform and the orientation of the major axes of the contact areas of each of said nozzles is not colinear; and applying a pressurized flow to said at least one spray arm such that a portion of the filter media passing between adjacent nozzles receives a pressurized spray applied from each of said adjacent nozzles.
