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.
Reverse osmosis has been understood since the middle of the eighteenth century. It took over 200 years for the theory to be put to practical use. University researchers in Florida and California developed a desalination process which Cape Coral, FL, began to use in 1977. This city still gets its municipal supply this way today, even though it now has quite a large population. The process is widely used in industry to keep even tap water from depositing minerals on machinery. City landscapers in dry areas like Los Angeles use it to reclaim rainwater for beautification programs.
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.
A lot of great things have come out of military necessity. Duct tape, the GPS in your car, the microwave in your kitchen, freeze drying, the Epipen that saves those in allergic reaction shock, the Jeep, and the computer were all developed by scientists and engineers for military use. Desalination of water is now helping people all over, as more than 15,000 plants provide fresh water where there was none.
Selling online has become so routine that maybe you're not surprised that you could buy a self-contained purification system set on a long trailer, ready to go wherever you want it to. Modern technology is a wonderful thing when it answers basic needs. The ROWPU 3000 and the Internet are examples of this.
