TLF-400DG

Summary

Product identification

The TLF Series comprises Ultra Low-Pressure and Low-Fouling Reverse Osmosis Membrane Elements. The specific product is the TLF-400DG. It features an improved cross-linked hydrophilic polymer layer designed to minimize foulant accumulation, reduce frequent chemical cleanings, and produce high-quality permeate at low energy from wastewater.

Products manufactured at the U.S. facility (TMUS) are certified to NSF/ANSI 61 for drinking water applications.
