Abstract
The objective of this project is the design, fabrication, testing and evaluation of an affordable, efficient greywater recycling system for Army mobile field kitchens/sanitation centers. The proposed system utilizes enabling technology, a medialess continuously self-cleaning rotary disk clarifier (RDC) to reduce turbidity and total suspended solids (TSS), in combination with commercial off-the-shelf (COTS) components: surface skimmer to remove fats/oil/grease (FOG), microfilters to further reduce TSS/turbidity, crossflow ultrafiltration to reduce dissolved organics (BOD/TSS/turbidity), regenerable packed bed media to further reduce BOD, and ultraviolet disinfection to inactivate bacterial coliforms. Target recycled greywater effluent performance goals that meet EPA secondary treated water quality standards are: BOD 5-day < 30 mg/L, TSS < 30 mg/L, no FOG, no coliforms, and turbidity < 5 NTU. Proposed system design goals: weight <130 lbs, small overall footprint, use <2 kW of power, ruggedized to travel as loose cargo in an Army truck bed, cost <$1000 (for >1000 systems), minimal maintenance/consumable parts, easy set up, operate in basic hot and cold environments (weatherized), and operate safely by non-technical military dishwashers. This system will be compared/contrasted with other types of conventional filtration systems. A fully automated pre-commercial recycling system will be independently field tested at a designated Army site.
