Early 19th century, the Rhine is very serious water pollution incident occurred (one of the world's water pollution incident three), 1826, Bonn, Germany, the Rhine water pollution spread in a small village, water has affected the local people's normal life, only 13-year-old PaulEric (Paul Eric) to drink clean water, he decided to make a superhuman wisdom water purifier, after going through hundreds of failures, eventually he successfully invented the world's first water purifier The water purifier is the thickness of the yarn with 20 bag filled with quartz sand and activated carbon, activated carbon in the middle of quartz sand, then this bag of water purification material on top of the barrel, the contaminated water poured in gauze top and let the water slowly flows through layers of penetration into the barrels of water purification equipment, after the final filtration rut observant sweet water purification equipment manufacturers, after repeated PaulEric improved water purifier filter water purification effect is getting better engineering equipment, causing the local government. With the general increase in people's awareness of water purification, water purification industry gradually on the rise, development of the domestic industry's net water from the 1980s began. Shanxi Run-Environmental Engineering Limited was founded in 2005, is a professional sewage treatment, waste gas treatment, dust handling and other environmental projects and research and design of high-tech enterprises. The company received wide attention and support from the community since its inception, and Taiyuan University of Technology, Taiyuan University of Technology, Institute of Nuclear Industry seventh, Shanxi Province Chemical Industry Design Institute and other internal and external universities, research institutes and design units to establish a province stable long-term close cooperation between the technology, with strong technical strength and excellent level of scientific research. Shanxi Run-Environmental Engineering Limited was founded in 2005 large-scale water purification equipment, is a professional sewage treatment, waste gas treatment, dust handling and other environmental projects and research and design of high-tech enterprises. Here to tell you about how to buy a water purifier based on water quality. 1, different water hardness in different parts of northern China and southern high hardness water quality limestone areas, water calcium and high magnesium ion content, easy to scale, you should buy with the ion exchange resin filter Advanced filter water purifier. 2, water, chlorine, heterochromatic odor heavier, organic matter content of more city water, activated carbon can buy large amounts of household water purifiers. Because of activated carbon for chlorine, heterochromatic odor has strong adsorption effect on removal of organic matter significantly. 3, for the urban and rural water is turbid water purification should buy coarse filter, fine filter dual function of household water purifiers. For serious water pollution, require completely filter out any impurities in the water, no heating drinkable, should buy reverse osmosis water. Jinzhong water purification equipment, water purification equipment manufacturers _ _ Run-Run-environmental protection provided by the Shanxi Environmental Engineering Limited.
