Toray RO Membrane Elements

Name: Toray RO Membrane Elements
Brand: Xinnian
SKU: TM710 / TM720D-400 / TML20D-400 / TM820M-400

TM710 / TM720D-400 / TML20D-400 / TM820M-400

Toray ROMEMBRA elements use a spiral-wound composite structure with a unique vented end cap and wide feed spacer, giving good resistance to fouling and pressure shocks in brackish water, seawater and industrial systems. Main models include TM710, TM720D-400, TML20D-400 and TM820M-400, and we can design the array around your water quality and recovery target.

Key Features

High rejection and high flow at low operating pressure
Wide feed spacer for fouling resistance and good cleaning recovery
Unique vented end cap for fast air removal and stable start-up
Suitable for brackish water, seawater and industrial reuse

Frequently asked questions

Are these membranes compatible with standard 8040 housings?

Yes, they follow the standard 8040 / 4040 dimensions and fit common fibreglass pressure vessels.

What salt rejection can I expect?

98.5–99.5% nominal rejection on 2000 ppm NaCl at standard test conditions; actual performance depends on pressure, temperature and recovery.

Do you provide element loading drawings?

Yes, we issue an array layout with the quotation so your team can load vessels correctly.
