Abstract: One possible embodiment of the invention could be a continuous flow separator for biodiesel formation and a method of operating same. The separator could comprise tank with hollow interior forming a main compartment, a weir-formed compartment, and a sump, the weir being formed at one end of the tank, the sump being formed in the tank bottom, the main compartment being located over the sump; a set of horizontally stacked plates received within the main compartment over the sump, each plate features a series of conical structures, cone apertures, and trough apertures; wherein the plates are so configured and stacked that the cone apertures align to form series of cone aperture columns while the trough apertures align to form series of trough aperture columns. The biodiesel moves up the cone aperture columns over a weir into the separate compartment while glycerine descends the trough aperture columns to the sump.
