Toray TMG20D-440 Brackwasser-Umkehrosmose-Membranelement

The membrane of the TMG20D-440 is a cross-linked, fully aromatic polyamide composite, manufactured by Toray under ISO 9001 with precision automated production. The result is high permeate quality combined with robust membrane chemistry – for reliable performance and long membrane life. The 28 mil feed spacer reduces pressure drop and makes the element less sensitive to fouling.

Thanks to its enhanced chemical tolerance, the element handles a pH range of 2–11 in continuous operation and 1–13 during chemical cleaning – ideal for plants with regular CIP cleaning. Typical applications include municipal drinking water treatment, industrial process water and water reuse. Elements of this series manufactured in the US are certified to NSF/ANSI 61 for drinking water applications.

IndustTech supplies the Toray TMG20D-440 in original packaging (vacuum-sealed in oxygen barrier bags) worldwide – fast, reliable and at fair conditions. Simply send us an inquiry with the quantity you need and we will prepare an individual quotation including shipping at short notice.
