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.
US Army research teams came up with the ROWPU 3000 to sustain troops in the field. The self-contained units are run on power from diesel generators and are mounted on thirty-foot trailers so they can be transported. The output is 60,000 gallons a day from fresh or brackish sources, and 40,000 gallons if they're using saltwater.
Today the various branches of the military have smaller units, capable of an output of from 125 to 1,200 gallons per hour. Some of them are self-propelled. For this reason, some ROWPU 3000 units mounted on thirty-foot trailers are available as army surplus. You can actually buy them online and have them shipped anywhere in the world - according to the internet.
Eskimos have lots of seawater; as long as the air temperature is no lower than -25F and they can cut a hole in the ice, the ROWPU 3000 will work. People on a desert island surrounded by seawater could use one to desalinate what they need. People who struggle on Indian reservations, forced to haul their drinking and household supply in in tank trucks at great trouble and expense, could have a dependable supply for themselves and their livestock.
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.
