Abstract: A process of and system for distributing, filtering, storing, recovering, and disposing of bulk edible oil or other fluid. The filtering system having a filter box assembly, superstructure and fluid transfer unit functions to filter the edible oil or other fluid, transfer the fresh (new) oil or other fluid for use in commercial vats and transfer spent (old) oil or other fluid to an outdoor supply and disposal storage tank. Two three-way valves coupled to two manual three-way valve switch handles operate to control the fluid transfer unit to intake fresh or old fluid and to dispense of the fresh or old fluid. A mobile transport truck couples to the outdoor supply and disposal storage tank for filling the supply and disposal storage tank with fresh (new) oil or other fluid and retrieves the spent (old) oil or other fluid.
