The fiber recovery system of claim 1, wherein the white water supply arrangement comprises a conduit arrangement located within an interior defined by the screen, wherein the conduit arrangement includes a series of openings through which white water is applied to the inside surface of the screen. 3. The fiber recovery system of claim 2, wherein the openings in the conduit arrangement are configured and arranged to apply a force to the inside surface of the screen tending to impart rotation to the screen about the axis of rotation of the frame arrangement. 4. A fiber recovery system for use in a papermaking process for recovering usable fibers contained in papermaking white water, comprising: a flexible and movable screen; a white water supply arrangement for directing papermaking white water onto a surface of the screen, wherein the flexibility and movability of the screen functions to vary the location at which the white water strikes the surface of the screen; wherein the screen is sized so as to retain usable fibers contained in the white water on the surface of the screen and to allow water and small particles of waste material contained in the white water to pass through the screen; a fiber collection and recovery arrangement for collecting usable fibers from a discharge area defined by the screen and for recirculating the usable fibers into the papermaking process; wherein the screen is suspended from a frame arrangement and defines a conical configuration having an upper end connected to the frame arrangement and a lower end defining the discharge area; and wherein the frame arrangement is rotatable about a generally upright axis of rotation coincident with a longitudinal axis defined by the screen. 5. The fiber recovery system of claim 3, wherein the white water supply arrangement comprises a conduit arrangement located within an interior defined by the screen, wherein the conduit arrangement includes a series of openings through which white water is applied to the inside surface of the screen. 6. The fiber recovery system of claim 5, wherein the openings in the conduit arrangement are configured and arranged to apply a force to the inside surface of the screen tending to impart rotation to the screen about the axis of rotation of the frame arrangement. 7. A method of recovering usable fibers contained in papermaking white water, comprising the steps of: directing the white water onto a surface of a screen at one or more impingement locatio
