A new promising water purification technology, soft fiber wadding filter, was introduced in this article. The technology has the advantages of energy saving and emission reduction efficiency greatly, is currently the most advanced water purification. This paper explains the structure of the technical equipment, tell the filtration principle, provides the filter parameters of practical efficiency, comparison. The technology is mainly used in power plants, metallurgy, chemical industry, oil field water treatment engineering, and achieved satisfactory results. Significance of the research on the model of water filtration equipment development and filtration theory is grearly.
