In this article we would like to consider one of these technologies. We begin, as usual, with the story: It all started with the fact that in 1748 a French scholar, monk Nolle, decided to have lunch. Before the meal he put the bull bubble with wine in the water, to realize their aim cool drink, and began to place on the table all that he had sent the God. But wine, unfortunately, that day he did not get to taste: whether God wanted to see a monk sober, or has decided to punish him for some sins, but the bubble of wine has increased in volume and burst. It turned out that the water penetrated into the bladder through his wall. So the monk discovered the phenomenon of spontaneous penetration through the film of low-concentration solution (natural water) in a more concentrated solution (wine). This phenomenon later became known as osmosis, and scientists began to pay attention to the thin film animal origin (membrane), which, to the surprise of researchers, have been porous. Membrane systems have long been a complicated and expensive and used mainly for smaller applications.
But by early 2004 there was a qualitative leap in the production of membrane materials and design of membrane systems, which led to a significant reduction in system cost and paved the way for wider use them instead of standard solutions. Water purification based on membrane technology. At present, membrane technologies are divided into two directions: First direction – the equipment for purification of surface and ground water without compromising tds.
