Abstract : A separator for immiscible fluids and particulate matter of differing densities provides a plurality of stages of fluid flow velocity reduction by change of cross-sectional areas between a plurality of flow regions (e.g. conduits and chambers) and separates a fraction of the introduced fluid or suspended particulate matter at each change of velocity whereby flow velocity may be reduced to a degree greater than accounted for by the change of cross-sectional area from stage to stage when significant amounts of materials to be separated are present in the input fluid. Further, a substantial effective length is provided, relative to the footprint of the separator. This length and gradual slowing of the fluids therein provides generally laminar flow and low turbulence. By doing so, overall volume of the passive separator is reduced and separation efficiency is substantially improved.
