- Commodity name: Industrial Nanofiltration Membrane Series Membrane Elements
Nanofiltration membrane has been widely used in the preparation of drinking water, food, pharmaceutical and biological industries without any chemical reaction, heating, destroying biological activity, altering flavor and aroma, low pressure and energy saving, and many other advantages. Focusing on the application fields of special substance separation and purification, fine salt separation, organic matter removal, zero discharge, drinking water for people's livelihood, process water supply, etc., Fumiao is the first one in China to research and develop the highly selective nanofiltration (NF) membrane element, which has high removal rate of divalent ions and ions above, organics with molecular weight above 200, viruses, etc., and excellent permeability of monovalent ions such as sodium and potassium.
