In the process of separation, nanofiltration membrane has no chemical reaction, no heating, no destruction of biological activity, no change of flavor and aroma, with many advantages such as low pressure energy saving, has been widely used in the preparation of drinking water and food, medicine, biology and other industries. Feymer membrane focusing on special physical purification, fine salt, organic matter removal, zero emissions, and the livelihood of the people drinking water, process water, and other areas of the application, research and development success NF225 selective nanofiltration membrane element, to divalent ions and above, more than 200 molecular weight of organic matters, such as virus has a high removal rate, and sodium, potassium and other monovalent ions through the performance.
