Many people in the world have little or no clean water. They live in high population areas where groundwater, lakes, and rivers are polluted. They live in the desert, where moisture is hard to find, or in arctic areas where everything is frozen. Trying to deliver the drinking and household supply from outlying regions is seldom practical. In many cases, obtaining a military surplus ROWPU 3000 water treatment unit would be a dream come true.
The acronym stands for 'reverse osmosis 3000 (gallons per hour) water purification unit'. Osmosis refers to the tendency of liquids to mix; in the process of reverse osmosis, liquid passes through a membrane with pores small enough to permit the pure liquid to seep through. However, microorganisms, particles, and larger ions and molecules are screened out. Chlorine is then used to completely disinfect the water for human use.
Scientists understood the process by 1750, but it took another 200 years before researchers developed a practical method for desalination. A few more years passed before the process was refined enough to be commercially viable. In 1977, the first municipality, Cape Coral, FL, used this process for its citizens. As the city grew, so did its water plant. Reverse osmosis is widely used in industry, to keep its machinery free of clogging mineral deposits, and by dryer regions like California to reclaim rainwater for city landscaping.
The military is often called on to operate in areas where only seawater or non-potable sources are available. They also have large numbers of troops that need a dependable supply. The US Army developed the ROWPU 3000. It provides up to 60,000 gallons a day if the source is fresh or brackish, and up to 40,000 if they are using seawater. The units run on electricity, but that can be supplied by a generator in remote or war-torn regions.
More modern units are smaller, capable of 125 to 1,500 gallons per hour. Some are self-propelled, making it easier to operate in remote areas. Because of these refinements, some of the large 3000 units are available through army surplus sales. You can actually see ROWPU 3000s advertised online. Apparently the sellers will ship them anywhere in the world.
Think of how great this would be for an Indian reservation, an isolated village with no well, or people trying to live on a desert island surrounded by ocean. Getting a unit with this kind of output capability could change lives. Eskimos could pump saltwater from under the ice, as long as the daytime temps are no lower than -25F and they can reach saltwater that's not frozen.
Military research and development has given us many valuable things. The GPS in your car or phone is one example. Microwave ovens, duct tape, freeze drying, the Epipen, the famous Jeep that goes off-road and on, and even the computer were first made for military use. There are now over 15,000 plants around the world desalinating seawater for human consumption.
It may seem strange to want a self-contained treatment plant mounted on a thirty-foot trailer that is powered by a diesel generator. However, there's a demand for these things, and they are like a miracle for those who need them. Modern technology can be a wonderful thing, especially when combined with GI ingenuity.
