What does reverse osmosis mean? We find this noted on numerous different brands of bottled water, and normally it's quite clear that it has got to be some sort of filtering process, but how does it actually work? In short, reverse osmosis is a type of filtering technology that works by using special purpose specific membranes. These kinds of membranes are essentially just filters, nonetheless in the case of reverse osmosis, the liquid which is to be purified is pressed through the membranes by applying pressure to the water. This technology is popular in the bottled water market, and can likewise be used to turn sea water into safe drinking water. The water, irrespective of whether fresh or from the sea, is pressed through the membranes under pressure. The membranes can prevent large molecules, such as salt for example, from passing through. They are also able to retain ions, which in turn means the water that passes through the membranes is for the most part untainted. Contrary to what many individuals often believe, reverse osmosis was first discovered inside a laboratory in 1748, but for some unknown reason, the concept was confined to laboratory use for approximately two hundred years. It wasn't until 1949 that research workers at the University of California started experimenting to see whether the idea could be used for eradicating salt from sea water. By the mid 1950's they had succeeded in converting sea water into healthy drinking water, however it turned out to be an incredibly lengthy task, and most certainly not a feasible option from a commercial point of view. Quite some time later, two scientists had learned how to make asymmetric membranes, and this basically allowed reverse osmosis to become a commercially workable option for the desalination of sea water. A lot of household water purification systems involve a reverse osmosis system. In most cases, tap water will go through a filter that traps any type of sediment which may be found in the water. After moving through the sediment trap, it will be forced through an activated carbon filter to remove chlorine and also any organic chemicals from the water. The filtered water then is subjected to reverse osmosis. In lots of systems, the water may even go through yet another activated carbon filter to catch chemical compounds that may have made it through the reverse osmosis step. More professional units can also often include an ultraviolet light that is used to sterilize the water by wiping out any unwelcome microbes. So, what does reverse osmosis imply, and can you really rely on this type of treatment with regards to having safe drinking water? Simply speaking, yes we can rely on it, nonetheless as with several things in life, you will need to concentrate on quality. Inexpensive systems will use inferior purification screens, and these will never be able to eradicate all sorts of toxins. Exactly what does RO mean?
