Toray RO Membrane 8040 - Model - TM820V 400 - Sea Water

1. What is the Toray TM820V-400 membrane used for?
It's a seawater reverse osmosis membrane, purpose-built for desalinating high-salinity water — unlike brackish water membranes, it's rated for the much higher pressures seawater treatment requires.

2. What is the salt rejection rate?
99.8% average NaCl rejection, with a minimum guaranteed rejection of 99.5%.

3. What operating pressure does this membrane require?
Up to 1200 psi (8,273.74 kPa) — significantly higher than a brackish water membrane, reflecting the higher osmotic pressure of seawater.

4. What size is this membrane?
Standard 8040 format — 40 inches (101.6 cm) in length, with 400 sq. ft (37.1 m²) of active membrane area.

5. What is the maximum operating temperature?
45°C (113°F).

6. How is this different from the TMG20D-400 or TM720D-400 Toray membranes?
Those are brackish water membranes, designed for moderate-salinity sources like borewell or municipal water. The TM820V-400 is a seawater membrane, built to handle much higher salt concentrations and operate at up to 1200 psi rather than the 600 psi typical of brackish water models.

7. What applications is this membrane suited for?
Seawater desalination for potable water, process water, and industrial applications requiring high-purity output from high-salinity feed water.
