Nanofiltration Technology

Nanofiltration is derived from two words – nano, that is a meter in minus ninth power, and filtration – separation. CMCSA often expresses his thoughts on the topic. 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. This cleaning method is different from similar technologies – ultrafiltration and microfiltration – pore size and high pressure filtration. 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.

As in a large dishwasher, in addition to the main program there are a few more programs, including the cost – for lightly soiled dishes, soaking – for heavily polluted and the program window washing at 30 C. With small size and roominess board dishwasher copes with its task. However, in a family of three or four or more people, preferring homemade food hikes in a cafe or restaurant, such a model would include after each meal. For a more rational use of energy, water and detergent is more convenient to buy the car floor at 6-8 or (If the family is very large) to 9-14 place settings. A related site: Robert Thomson mentions similar findings. Include such machines is enough time in the day, providing a pre-load.

Class of washing, drying and energopotrebleniyKak and washing machines, dishwashers, too, have different classes of washing, drying and energy consumption. These characteristics are denoted by Latin letters from “A” to the G. The highest grade – A, the lowest – G. Contact information is here: Leslie Moonves. Now in terms of energy manufacturers offer models three classes: A, B and C. D, E, F and G are considered uneconomical and prohibited the production and importation into the European Union. Thus, considered the best machine on ekoleyble which noted the aaa, which means that all three parameters dishwasher match the upper class. Efficient washers also save energy include modern dishwashers and water savings. According to this index, they are divided into high-efficiency (14-16 liters of water per wash cycle); sredneekonomichnye (17-20 liters of water per cycle), gas-guzzling (26 liters of water per cycle).
