Engineering summary from PDF text extraction for SU-720TS. Verify every value with the OEM datasheet.
Summary
Product Identification
Toray's TS SU Type are heat-sanitized brackish water reverse osmosis membrane elements with outer permeate tube connection. They are designed to provide superior permeate quality for applications requiring hot water sanitization, eliminating the need for chemical sanitization. The RO elements use cross-linked fully aromatic polyamide composite membranes.

Operating Limits
The following are recommended design conditions. Operation outside these ranges may reduce effective membrane life.
- Feed water pressure: < 2.0 MPa (286 psi)
- Maximum Feed Water Pressure: 4.1 MPa (600 psi)
- Feed water temperature: < 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 (measured according to ASTM D4189)
- High flux operation with feed water turbidity greater than 3 or 4 SDI generally requires frequent cleaning.
- Feed water pH range:
- Continuous operation: 3–9
- Chemical cleaning: 2–10 (for SU-710T), 2–11 (for 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)
- This figure is reducible when there is less possibility of fouling and scaling.
- Brine/Permeate flow ratio (at last element): > 6
- Pressure drop per element: < 0.1 MPa (14 psi)
- Pressure drop per vessel: < 0.2 MPa (29 psi)
- Elements must be cleaned when pressure drop increases up to 1.5 times of initial value.
Applications
- Municipal drinking water
- Industrial process water
