Product Introduction：
The Nainona membrane element uses imported diaphragms with excellent molecular rejection and is able to efficiently remove dissolved salts from wastewater. The special encapsulation technology is used to reduce the permeability of the salt seal in the high-pressure environment, improve the overall salt water retention performance, and also have excellent performance in the hardness of decolorization and softening groundwater. It achieves efficient separation at low pressure, is easy to clean, and can also be widely used in food and beverage, biopharmaceutical, biomedicine and other fields.
Application scenarios: leachate decolorization, dye decolorization, chlor-alkali denitrification, wastewater salting, etc
