Abstract"Military field feeding operations require an easily transportable and energy-efficient system to recycle the greywater produced in ware washing. A multiple-effect evaporator is proposed that will distill the greywater, heated by a diesel/JP-8 powered oilburner or other available liquid/vapor heating medium. It is designed to recover at least 90% of the greywater as potable hot water or steam to be used for warewashing, using as little as 0.02 lb of fuel per pound of greywater. The Phase I project willevaluate the feasibility of an innovative compact multi-effect evaporator module that facilitates accessibility for cleaning and can be adapted to a wide range of heat sources. The proposed multi-effect evaporator module can process greywater generated byfield laundries and showers, in addition to field feeding operations, and can be used to purify brackish water. It could find many non-military applications, such as in disaster relief where potable water supplies have been disrupted, or in arid regionswhere greywater recycling and brackish water purification would increase the net supply of potable water."
