Keensen Material Separation Nanofiltration Membranes/RO Membrane with Low Pressure NF2-4040F Company Profile KeenSen Technology Co., Ltd., was established in May, 2008, is a professional manufacturer, specializing in professional separation membrane production and applications with its head office located in the High-tech Industrial Development District in Changsha, China. KeenSen RO and NF membranes elements can be widely used in more than 50 industries, including water treatment projects, environmental restoration project, and direct drinking Water system, etc. It will help human being to up against resource shortages and environment pollution.
Product Description 1. KeenSen NF2-4040F membranes series are mainly applicable to concentration or separation of dye, removal of heavy metal, the recycling of sodium chloride solution, the treatment of landfill leachate and coking wastewater. 2. Higher than divalent ions are preferentially trapped by the material separation membranes, the retention of monovalent ions will be affected by the material liquid density.
