Description

The FR11-4040 Reverse Osmosis Membrane is a fouling-resistant thin-film composite (TFC) membrane designed for challenging water treatment applications where surface water, reclaimed water, and industrial wastewater are used as feed water. Its specially engineered membrane surface improves hydrophilicity, optimises surface charge, and reduces surface roughness, helping to minimise the build-up of organic contaminants and microbial fouling.

The FR11-4040 membrane is ideal for producing high-quality purified water from lakes, rivers, reclaimed water, and industrial process water. Its excellent salt rejection and fouling resistance result in longer operating cycles, reduced cleaning frequency, and lower operating costs, making it an excellent choice for commercial and industrial Reverse Osmosis (RO) systems.
