Feasibility study for small-group water desalination equipment. Final report, February-August 1984
The ability for small groups of soldiers to desalinate brackish or sea water will reduce their dependence on supply lines. Ten desalination options were reviewed for effectiveness in nine scenarios. Each option was rated according to a number of factors such as energy consumption, water recovery, logistics concerns, weight, and simplicity. The importance of each of these factors depended on the scenario being considered. These options included simple distillation, single-pass membrane distillation, multiple-pass membrane distillation, multiple effect evaporation, heat pumps, vapor-compression, reverse osmosis without energy recovery, reverse osmosis with energy recovery, electrodialysis and ion exchange. The nine scenarios include: using waste heat from vehicles, using power take-off from vehicles, using a trailer mounted unit performing desalination on the move or in a fixed location, stowing a small desalination unit in vehicles to be used when needed, using waste heat at a fixed location, using a dedicated power source for a desalination unit at a fixed location, using waste heat from a microclimate cooling unit, and having a soldier carry the desalination unit. From this analysis, it was determined that simple distillation, membrane distillation, reverse osmosis, and vapor-compression were viable options.
