DF90 (Ultra-Low-Pressure High Rejection Nanofiltration Membrane)
The DF90 (Ultra-Low-Pressure High Rejection Nanofiltration Membrane) can highly reject salts and effectively remove small organic compounds, eg. insecticide, herbicide, etc., , as well as bacteria and viruses, and is featured with low operating pressure, high permeated flow and high recovery rate. The product is one of the significant achievements in Major Science and Technology Program for Water Pollution Control and Treatment during “the 12th Five-Year Plan” and has been selected as the Major Environmental Protection Equipment Encouraged by the State and the First Major Technology and Equipment Demonstration Project in Zhongguancun National Independent Innovation Demonstration Zone. In addition, it has been awarded with
multiple awards, such as the Beijing New Technology and New Products, the National Strategic Innovative Products and the National Key New Products, as well as the China Excellent Patent Award, the First Prize of Science and Technology Progress of Ministry of Education, the Second Prize of National Scientific and Technological Progress Award , etc.
High retention rate: High removal rate for small organic compounds, eg., insecticide, herbicide etc., as well
as bacteria and viruses ,etc;
High recovery rate: The water recovery rate of the system reaches as high as 85%, and is above 10% more
than the traditional low-pressure RO membrane;
Low operation pressure: The system operation pressure is 0.4~0.7MPa and is above 30% lower than the
traditional low-pressure RO membrane;
Low operation cost: Long cleaning interval, less chemical consumption and less maintenance cost.
