Regulatory Information
Toray's membrane elements are certified under:
- ISO 9001:2015 QMS
- ISO 14001:2015 EMS Components conform to FDA Regulation CFR Title 21 and USDA/3A Sanitary Standards (for Spiral Elements in Sanitary Design without ATD). TMRO 8040 models (with ATD) conform to FDA Regulation CFR Title 21.
Operating limits
- Maximum operating pressure: 800 psi (55.2 bar)
- Maximum operating temperature: 122°F (50°C)
- Maximum operating temperature for HPRO: 150°F (65°C)*
- Maximum cleaning temperature: 122°F (50°C)
- Acceptable operating pH range: 2.5–10.5
- Acceptable short-term cleaning pH range: 1.7–11.5
- Maximum pressure drop per element: 15 psi (1.0 bar)
- Maximum pressure drop per vessel: 60 psi (4.1 bar)
* For High-Pressure Reverse Osmosis (HPRO) elements, consult Toray for pressure limits when operating above ambient temperature. New HPRO elements intended for operation above 122°F (50°C) must undergo a specific pre-conditioning procedure detailed in the full document.
Oxidant Tolerance
- Chlorine tolerance (short-term cleaning at pH 11): Non-detect
- H₂O₂ continuous: 20 ppm*
- H₂O₂ short-term cleaning <77°F (25°C): 1,000 ppm*
* Free chlorine should not be present in feed.
Feed water
The conditioning procedure for HPRO elements requires high-quality chlorine and oxidant-free, non-scaling, non-fouling water, with RO permeate being preferred.
Performance / Test Conditions for High-Pressure RO
- Feed water pressure: 800 psi (55.2 bar)
- Feed water temperature: 77°F (25°C)
- Feed water concentration: 32,000 mg/l as NaCl
- Feed water pH: 8
Product water
Performance / Test Conditions for High-Pressure RO
- Rejection rate: 99.8%
- Flux rate: 17.5 gfd (30 lmh)
- Recovery rate: 8%
Mechanical / Hydraulic
Elements are available in "Spiral Elements in Sanitary Design (no ATD)" and "TMRO 8040 models (w/ ATD)" configurations. Refer to the "Standard Dimensions" table under Product Identification for specific element diameter, length, and permeate tube inner diameter.
