Toray is a representative Japanese membrane manufacturer. Its product line covers brackish water (TM720 series), seawater (TM820 series), ultra-low pressure (SUL) and fouling resistant (TLF/TBW). Toray holds a high installed share in large seawater desalination projects and semiconductor ultrapure water systems.
Its model suffixes carry a lot of information: D usually denotes a high-rejection version, L low pressure / low energy, R high rejection, and F fouling resistant. Confirming suffix meanings before reading a model is faster than looking up each element in a table.

How to select
- Seawater projects: TM820 series; check pressure resistance and per-element pressure drop; recovery is typically 40%~45%.
- Brackish water baseline: TM720D-400, 99.8% rejection, suited to systems sensitive to permeate TDS.
- Low-energy retrofit: SUL-G20, which can markedly lower operating pressure when replacing elements in older systems.
- High fouling load: TLF/TBW series, together with a lower design flux.

FAQ
Which country does the Toray RO membrane come from?
Toray Industries, Japan, headquartered in Tokyo; its membrane products are widely used in seawater desalination and ultrapure water.
What is the difference between TM720 and TM820?
TM720 is the brackish water series for lower-salinity applications; TM820 is the seawater series with higher pressure resistance, suited to seawater at the 35000 mg/L level.
What design software does Toray provide?
Toray DS2, a Windows desktop application; project files use the .tds2 extension.
Why does Toray membrane rejection come in 99.7% and 99.8% grades?
Separation layer processes differ between models; high-rejection models such as the D series are rated at 99.8%, while standard models are mostly 99.7%. Selection should consider operating pressure together with water quality requirements.
