Abstract:
A rotating drum screen method for separating solids from thin stillage obtained from ethanol fermentation, the thin stillage comprising one or more of solids and suspended solids. Thin stillage is chemically treated with an anionic polymer to form stable particles of one or more of solids and suspended solids. Introducing the treated thin stillage into a rotating drum screen system. The drum screen includes a filter screen that retains at least a portion of the solids within a hollow portion of the drum screen and which produces a liquid effluent that is discharged from an outer surface of the drum screen. The retained solids are removable from the drum screen via a solid discharge end. A head box is disposed within the hollow portion of the drum screen and has a plurality of fluid flow channel dividers dividing and directing an influent stream outwardly against the drum screen.

Claim (Index 14):
A rotating drum screen method for separating solids from thin stillage obtained from ethanol fermentation, the thin stillage comprising one or more of solids and suspended solids, the rotating drum screen method comprising:\n chemically treating the thin stillage with an anionic polymer a molecular weight greater than 10,000,000 Da to form stable particles of one or more of solids and suspended solids; introducing the treated thin stillage into a rotating drum screen system comprising:\n a housing having an influent inlet at an influent inlet end, a solid discharge end and an area between the influent inlet end and the solid discharge end, the influent inlet permitting a flow of treated thin stillage into a hollow portion of a drum screen positioned lengthwise in the area between the influent inlet end and the solid discharge end, the drum screen comprising a filter screen that retains at least a portion of the stable particles within the hollow portion of the drum screen and which produces a liquid effluent that is discharged from an outer surface of the drum screen, the retained stable particles being removable from the drum screen via the solid discharge end, wherein the filter screen has a size in the range of 25 \u03bcm and 150 \u03bcm; and \n a head box disposed within the hollow portion of the drum screen proximate the influent inlet end and in fluid communication with the influent inlet, the head box comprising a plurality of parallel fluid flow channel dividers dividing the flow of treated thin stillage received at the influent inlet into a plurality of parallel ongoing streams; and \n directing the plurality of ongoing streams outwardly against the drum screen wherein the filter screen retains at least a portion of the stable particles and produces the liquid effluent that is discharged from the outer surface of the drum screen.
