Vontron ULP11-4040 Reverse Osmosis Membrane – 4″ × 40″

VONTRON Reverse Osmosis Membrane 

The Vontron ULP11-4040 Reverse Osmosis Membrane is a high-performance ultra-low pressure (ULP) membrane designed to deliver reliable salt and contaminant rejection while operating at significantly reduced feed pressure compared to conventional RO membranes.

Engineered for efficiency, the ULP11-4040 is ideal for applications where energy consumption, pump sizing, or operating pressure limitations are critical considerations. It provides stable permeate flow and consistent rejection performance across a wide range of operating conditions, making it well suited to light commercial, industrial, and specialised residential RO systems.

Manufactured in the standard 4″ × 40″ configuration, this membrane is compatible with most industry-standard 4040 RO pressure vessels and systems. Typical applications include potable water treatment, pre-treatment for polishing systems, commercial filtration, and process water where low-pressure operation is preferred.
