Nano technology has covered a vast range of facilities and applications. It is one of the most extraordinary technologies of the 21st century. Pollution of drinking water sources and impossibility to treat and purify polluted sources with conventional methods on one hand, and nitrate pollutants in underground resources are among the dangers that make the need to adopting alternative methods of purification more tangible.
One of these methods is nano-filtration which has received good attention across the world in recent years. The ability to remove bacteria and viruses is very high in this method and compared to reverse osmosis (RO) method, NF is more economical and has easier utilization.
Today, more researches are being done on new applied studies such as removing single capacity ions. Separation in those membrane works based on filtering mechanism and on the other hand, as the membranes are charged, the reaction between membrane and passing fluid are effective in the separation process.
Nano filtration is one of the membrane purification methods that remove many compounds with high molecular mass and water solubility. The nano-filtration membranes remove water hardness except few ions with low molecular mass that are useful for body. This method also removes larger organic molecules such as water color, almost all viruses, many natural organic substances and some of the salts. The holes size of nano-filtration filters is around 0.001 micron.
Pala Gostar Sanat Ab Company, with the aim of specialized and professional activities in the area of design and manufacturing of new water and sewage purification system as well as achieving technical knowledge of designing the omission pollutants from environment in water and sewage area, tries to offer the best approaches with most inexpensive prices to officials in order to supply people especially deprived people of the country with inexpensive technologic methods of water purification.
