ABSTRACT:
Liquids, specifically liquids containing suspended matter, may be treated by passage through a separator comprising means dividing the container into a first section, intermediate section and third section, with a flat topped weir dividing the first section from the intermediate section. The width of the flat topped weir is selected so that liquid flow over the weir is laminar. At least the flat topped portion of the weir is provided with a smooth surface so as to reduce friction and boundary effects which distort the desired flow pattern. This smooth surface may be constituted by an L-shaped stainless steel plate. The interior side walls of the container in the vicinity of the flat top of the weir may be coated with a two-part epoxy to provide smooth surfaces.
