At present, the water purification machine brand on the market is multifarious, studied the water purification machine instructions, always see micro filtration, nanofiltration, ultrafiltration, reverse osmosis, this a few words.
Warns a citizen, let various & other;
Filter & throughout;
Lose your head, be clear about the study of water purifiers consumption concept.
the filters filter dedicated category description: microfiltration ( Also called coarse filter) : it is a simple filter, filter material is generally used PP cotton filter and quartz sand, activated carbon filter, or particle or compression KDF particles, etc. The microfiltration membrane aperture are generally at 0. 5 - 1 micron, can only play a filter sediment, rust, colloid and other visible impurities and bacteria. Water treated by microfiltration membrane, but only on the senses to clear, and not as a qualified water to drink, is the market see more simple filtration unit. Ultrafiltration (
Hereinafter referred to as UF) : also called hollow fiber, is the use of ultrafiltration membrane pore size separation of liquid physical screening process; The aperture is commonly 0. 1 - 0. 01 microns, mainly in water treatment can filter bacteria, viruses, large molecules such as organic carbon powder, but for pesticides, herbicides, detergents and other low molecular organics, heavy metals and in running water transport process of the harmful material such as iron, manganese ion can't effectively remove; In general, ultrafiltration aperture reached 0. 01 micron ultrafiltration water purification products direct drinking purified water can reach the standard, but the overall filtering effect and taste bad water quality.
of ultrafiltration membrane pressure difference as driving force for the ultrafiltration membrane filtration membrane filtration method. Ultrafiltration membrane mostly by acetate or its performance is similar to polymer materials. Suitable for processing the solute in the solution of separation and enrichment, and also used in other separation technology is difficult to complete the separation of colloidal suspension, in expanding its application field.
nanofiltration ( NF) : the filter aperture range from 0. 01 - 0. 001 microns; To filter out antibiotics, hormones, pesticides, oil, detergent, chemical pollutants such as heavy metal, algal toxins; But smaller than the pore size of mineral ions can be made; Can effectively keep the beneficial minerals. Reverse osmosis (
RO) : the use of special high pressure water pump, increase the raw water pressure, make the action of raw water in pressure infiltration through the pore diameter is only 0. 0001 microns reverse osmosis membrane. Chemical ion and bacteria, fungi, viruses cannot pass, along with the waste water discharge, only allow volume less than 0. The pure water molecules through 0001 microns, which is pure water. Do not contain minerals beneficial to human body, long-term consumption of the human body.
