A functional model for the collection and storage of fecal wastes in a biologically safe and psychologically acceptable manner for aerospace vehicles has been designed, fabricated and successfully tested. The design is a commode type collector similar to the previously developed 'Dry-John slinger' system; however, the new design extends the useful life of the previous unit by use of a replaceable liner. The functional model provides vacuum drying and storage of 200 man-days of feces and toilet tissue prior to liner replacement. Each liner contains a motor-slinger and an air flow bacteria filter. The filter prevents contamination of all downstream lines and permits changing of the liner without contamination of the cabin. The full liner can be sealed and stored while the new liner functions for an additional 200 man days; thus, the useful life of the basic hardware is governed by the number of available liner assemblies, and cabin storage. Additional features of the functional model are a quick acting slide valve assembly to open and close the commode, provision for feces sampling and a subassembly for dispensing a disinfectant onto the feces.
