ABSTRACT:
A method and apparatus for optimizing operation of a filter system supplying filtered fluid to a process system characterized by varying demands for filtered fluid, a pump being operable at a varying flow rate for supplying inlet fluid to the filter system and developing a supply of outlet filtered fluid for the process system, a selected parameter of the process system indicative of its demands for filtered fluid being sensed in order to generate representative feedback data and regulating operation of the filter system pump to supply inlet fluid to the filter system at a rate determined by the feedback data whereby the filter system operates at a variable rate in proportion to the varying demands of the process system. Operation of the filter system pump is preferably regulated by adjusting either its operating speed or volumetric stroke. Parameters for the processing system include either the fluid level in a holding tank between the filtering system and the processing system or another condition of the process system. The introduction by bodyfeed systems of one or more filter aids to a filter element in the filter system is also regulated according to different variable conditions for optimizing filter system operation.
