SU-720T
Engineering summary from PDF text extraction for SU-720T. Verify every value with the OEM datasheet.
Summary
Product identification
Toray's TS SU Type membranes are heat-sanitized brackish water reverse osmosis (RO) membrane elements with an outer permeate tube connection. They are designed to provide superior permeate quality for applications requiring hot water sanitization, eliminating the need for chemical sanitization and reducing maintenance costs.
The RO elements utilize cross-linked fully aromatic polyamide composite membranes.
Applications:
- Municipal drinking water
- Industrial process water
Available Models:
- SU-710T
- SU-720TS
Product specifications
- Membrane Type: Cross-linked fully aromatic polyamide composite
- Heat Sanitization: Up to 90 °C (194 °F) for SU-710T and 85 °C (185 °F) for SU-720TS.

Operating limits
The following are recommended design conditions. Operation outside of this range may reduce effective membrane life.
- Feed water pressure:
- Recommended: < 2.0 MPa (286 psi)
- Maximum: 4.1 MPa (600 psi)
- Feed water temperature:
- Recommended: < 35 °C (95 °F)
- Maximum Sanitization Temperature: 90 °C (194 °F) for SU-710T; 85 °C (185 °F) for SU-720TS
- Feed water turbidity (SDI): < 4 (SDI measured per ASTM D4189)
- Feed water pH range:
- Continuous operation: 3–9
- Chemical cleaning: 2–10 (SU-710T), 2–11 (SU-720TS)
- Feed flow rate per vessel:
- SU-710T: < 50 l/min (13 gpm)
- SU-720TS: < 200 l/min (52.8 gpm)
- Brine flow rate per vessel:
- SU-710T: > 10 l/min (2.6 gpm)
- SU-720TS: > 40 l/min (10.6 gpm)
- Brine/Permeate flow ratio (at last element): > 6
- Pressure drop:
- Per element: < 0.1 MPa (14 psi)
- Per vessel: < 0.2 MPa (29 psi)
Notes on Operating Limits:
- High flux operation with feed water turbidity greater than 3 or 4 SDI generally results in frequent cleaning requirements.
- Element(s) must be cleaned when pressure drop increases up to 1.5 times the initial value.
- Sanitization must follow guidance in Toray's membrane manuals.
