NOVELTY - Potable water is produced from ethanol fermentation still bottoms by separating pasteurized still bottom liquid from solid organic and inorganic components by continuously subjecting still bottom liquid to coarse solids separation by centrifugation, evaporation, or microfiltration, followed by pressurized membrane filtration. The separated solid concentrate fractions are anaerobically digested after beneficial properties are recovered. The rendered liquid is subjected to pH adjustment, pressurized reverse osmosis through semi-permeable membrane, and finishing step.    USE - For producing potable water used for recycling, discharge, or human consumption by bulk handling or bottling.    ADVANTAGE - The process reduces the volume of solids to manage, recovers water from the fermentation still bottoms while pasteurized, maintains the chemical and physical properties of solids for beneficial property recovery, improves ethanol and energy efficiency, and results in clean discharge to the environment including carbon dioxide recovery.    DETAILED DESCRIPTION - Potable water is produced from ethanol fermentation still bottoms by separating pasteurized still bottom liquid from solid organic and inorganic components by continuously subjecting still bottom liquid to steps that further separate organic and inorganic concentrate fractions of solids of lesser weight from the still bottom liquid. The separated solid concentrate fractions are anaerobically digested after beneficial properties are recovered. The separation steps include coarse solids separation by centrifugation, evaporation, or microfiltration, followed by pressurized membrane filtration, e.g. microfiltration, ultrafiltration, or nanofiltration, to further separate solids. The rendered liquid having predetermined composition and solids content is subjected to pH adjustment to a predetermined pH level, followed by pressurized reverse osmosis through a semi-permeable membrane having a molecular weight pore size of 50-100 Dalton to produce a reverse osmosis concentrate and a reverse osmosis permeate, followed by a finishing step to the permeate to yield potable water product of low molecular weight solids. An INDEPENDENT CLAIM is included for a potable water production device.    DESCRIPTION OF DRAWING(S) - The figure is a conceptual diagram of a method for treating ethanol fermentation still bottoms.
