Water buy 1, different water hardness in different regions of northern China and southern high water hardness limestone areas, water calcium and magnesium ion content high, easy to scale, should buy with an ion exchange resin filter Advanced filter water purifier. 2, water, chlorine, heterochromatic odor heavier, household water purification equipment manufacturers, organic matter content of more urban water supply, can buy large amounts of activated carbon home water purifier. Because the activated carbon to chlorine, there is strong adsorption of heterochromatic odor, household water purification equipment brands, significant organic matter removal. 3, more turbid water for urban and rural water quality purification of household water purification equipment principle, should buy coarse filter, fine filter dual function of home water purifier. For severely contaminated water, household water purification equipment, requires completely filter out any impurities in the water, no heating drinkable, should buy reverse osmosis water. White household water purifier microfiltration and ultrafiltration microfiltration is made of cellulose or polymer materials, porous membrane, with its uniform pore size to particles trapped in the water, bacteria, colloids, etc., so that it does not pass through the membrane It was removed. This microporous membrane filtration technology, also known as particle density filter technology to filter micron or nanoscale particles and bacteria. Ultrafiltration and microfiltration membrane separation technology belong to, there is no clear line between the two, ultrafiltration working pressure generally about 0.3 MPa, can remove macromolecules, bacteria, viruses, etc., but lower flux . Yue Han Technology (FIG), the price of household water purification equipment, household water purification equipment provided by the Henan Science and Technology Co., Ltd. Han Yue. Henan Yue Han Technology Co., Ltd. (www.hnlyjd.com/) is located in Zhengzhou City, Tongbai Road Royal Lake Palace East Garden, Building 8, Unit 1, 1602.
