Many are interested in such a strange name the phenomenon "reverse osmosis."It comes from the Greek word for pressure or push.It refers to the spontaneous process transfer agent, usually water, through the membrane - a semipermeable membrane which separates two solutions having excellent concentration.This may for example be a saline solution, and pure water.
technology
When the membrane, only the water flowing in a more concentrated substance, blocking the way the dissolved elements, then at some point an equilibrium.Pressure, lined on both sides of the partition is called osmotic.This phenomenon is used since the seventies of the last century for the treatment of water, especially in the production of drinking from the sea.
Today, reverse osmosis is probably the most advanced technology.It is based on the use of the membrane of the same name.It is believed that it is able to purify water from any available natural impurities.
History of
Osmosis reverse, the process of separation of solution components from each other, has a fairly long history.Even the ancient Greeks, especially Aristotle, it was noted that the passage of sea water through the vessel wall of wax she desalted.
study of membrane processes in detail only began in the early eighteenth century, when the Reaumur for scientific purposes were used semipermeable membrane nature.However, until the twenties of the last century, these processes do not extend beyond the laboratory tests.
In 1927 the German firm "Sartorius' were first obtained samples of artificial semi-permeable barriers.Development of technology was the impetus to that used in reverse osmosis filters in industrial and household conditions.
After the war, the Americans, based on the work of the Germans, began to produce cellulosic membranes.And only in the late sixties, when it began to spread the production of synthetic materials, began to conduct the first research and development, which became the base of industrial applications osmosis.
are already widely installed similar systems in place to be drinking water with a maximum degree of purification.Its composition is obtained at the output of the system "reverse osmosis" is considered environmentally friendly.According to its characteristics it is close to the ancient glaciers melted water.
Application
Water filters - reverse osmosis - is connected to the water supply, which comes from a designed to clean water, while the impurities are selected go down the drain.The process includes a pre-treatment operation and pass through the membrane.Thereafter, the flow, getting first to the drive, which is going to purified water, is already in the final cleaning, and then - in the faucet.
filter reverse osmosis is today the most economical, versatile and reliable method.It allows you to reduce the concentration of dissolved and colloidal dissolved components is almost one hundred per cent, saving the liquid from viruses and microorganisms.
most significant in this whole process is a pretreatment.In this system the membrane (reverse osmosis) - the most expensive interchangeable element.Term of its work depends, first, on the quality of the incoming water.At this stage the three filters in series, whose task is to prepare the fluid to pass through the membrane.
