Microporous membranes performance study of dealing with the water
Abstract:With the rapid development of social economy and people life level unceasing enhancement, the existing water supply industry is facing unprecedented challenges. Emissions of pollutants on the one hand, the production and life more and more, lead to the majority of urban groundwater by a certain degree of dot and pollution, and has a tendency to increase year by year. The use of the increasingly serious water pollution not only reduces the water functions, further aggravated the contradiction of water shortage, to our country is implementing the strategy of sustainable development has brought serious impact, but also a serious threat to urban residents of the drinking water safety and people's health. In pharmaceutical engineering and medical fields, on the other hand, the demand for water is becoming more and more big. So how to develop new technologies to purify water, and improve the capacity of purified water is needed by the society at present.
In recent years, due to the microporous membranes performance improving, can efficiently deal with tap water to make it conform to the standard medical water and can be effective treatment of sewage, and lower production cost. Making it widely used in processing medical water and drinking water treatment.
