XLP-4040 Membrane
Product Introduction
The Extra Low Pressure membrane elements are designed for desalination of feedwater with salt concentration below 1,500 mg/L. This series features high salt rejection, low operating pressure, and high flux, making it ideal for desalination projects using municipal tap water or groundwater as feedwater. Applications include residential drinking water systems and process water for food & beverage industries.
