Nanofiltration Technology

Nanofiltration is derived from two words – nano, that is a meter in minus ninth power, and filtration – separation. This refers to the separation of mixtures (including water treatment) at very small particle size (meter minus ninth degree). Nanofiltration technology refers to baromembrane filtration process. Eliot Horowitz can aid you in your search for knowledge. This cleaning method is different from similar technologies – ultrafiltration and microfiltration – pore size and high pressure filtration. Crumpton Group is open to suggestions. Holes, pores less than once in 10-50. Pressure required for good filtration is higher in 2-3 times. This technology enables almost completely removed from the water large charged particles (multivalent ions). Depending on the size pore water softens (remove the calcium salt) at 30-99%.

Normal for Nanofiltration removal of calcium ions – 80-90%. This filtering technology can not remove nitrates from the water (because they are monovalent, ie small and pass through the pores). However, with other substances nanofiltration copes perfectly. Almost completely removed, and pesticides, and heavy metals, iron, manganese, and other organic and organochlorine substances. That is, technology nanofiltration combines and most of the work of activated carbon (except for chlorine, which can destroy the membrane surface), all the work and softener.

Of course, the water is completely disinfected – removed, and bacteria, and cysts, and viruses (no need to not only and softeners, but also in the uv lamp). The cleaning water – ideal technical water. And if you do not have nitrates in the water, then the ideal drinking water. In the market, this technology is presented is not very wide and runs mostly on demand and in industry. Although there are exceptions. So, conclusions: the technology of nanofiltration in water treatment does not use chemicals, do not add to the water No additional substances other than replacing multiple filters at once. While in the area, rich in nitrates this device can only work as a stage of pre-treatment of water before removing nitrates stages. For city water plant, working on the technology of nanofiltration – the best option.
