Reverse Osmosis Membrane 1812
Overview
The Reverse Osmosis (RO) membrane element is specifically engineered for the treatment of low-salinity water sources, including tap water and well water. Designed to operate under extra-low pressure, it is suitable for use in water purification systems for residential, hospital, and laboratory applications.
Key Features:
-
Membrane Type: Polyamide Thin-Film Composite
-
Designed For: Low-salinity water treatment
-
Applications: Residential, hospital, and laboratory water purification
-
Operating Pressure: Extra-low pressure for enhanced efficiency
-
NSF/ANSI Standard 58 Listed: Ensures reliability and safety for home drinking water systems
-
Long Shelf-Life: Membrane elements are shipped dry for easy handling and extended storage life.
