TSF06 SW-8040-MAX

Engineered for High Salinity | Made in Oman | Superior Performance.

The Tasnee SW Membrane is a premium Reverse Osmosis (RO) membrane element specifically designed for seawater desalination. Manufactured in Oman by Tasnee, it is built to deliver high salt rejection, excellent durability, and energy efficiency in harsh saline conditions.

Applications:

• Desalination plants (municipal & industrial).
• Marine & offshore platforms.
• Resorts, islands, and coastal communities.
• Power and utility sectors.

Key Features:

• 8040 Standard Size – Universally compatible with most seawater RO systems.
• High Rejection Rate – Removes >99.7% of total dissolved salts (TDS).
• Robust Design – Withstands high operating pressure and challenging feed water.

Backed by Tasnee’s in-house R&D and strict quality control, our SW membranes offer reliable performance tailored for Middle Eastern seawater conditions, aligning with Oman’s sustainability goals and regional water security needs.
