TS SUL Type Heat-Sanitized Brackish Water Reverse Osmosis Membrane Element with Outer Permeate Tube Connection.
Toray's Heat-sanitized RO membrane elements provide superior permeate quality for applications requiring hot water sanitization. Using heat-sanitized RO elements eliminates the need for chemical sanitization, further reducing maintenance costs. RO elements use cross-linked fully aromatic polyamide composite membranes.
Test Conditions: Feed water pressure 110 psi (0.75 MPa); Feed water temperature 25°C (77 °F); Feed water concentration 500 mg/L as NaCl; Brine fl ow rate 20 l/min (5.3 gpm) for SUL-G10TS, 80 l/min (21.1 gpm) for SUL-G20TS and SUL-G20FTS; Feed water pH 6.5.
Applications ：Municipal drinking water, Industrial process water.
TS SUL Type Heat-Sanitized Brackish Water Reverse Osmosis Membrane Element with Outer Permeate Tube Connection.
1.The recommended design range is operational and design conditions under not so much fouling and scaling. If the SUL-series element are operated outside of the recommended design range, the effective membrane life may be reduced. Refer to Toray's membrane manuals on our website (www.water.toray), or contact Toray or a local distributor for design guidelines and further information.
2. High flux operation (under high permeate flow rate per single element) on feed water turbidity greater than 3 or 4 SDI generally results in frequent cleaning requirements. Select the operating pressure to maintain the flux or permeate flow rates per single element.
3. The maximum Feed Water Pressure is 4.1 MPa (600 psi).
4. The maximum Sanitization Temperature is 85 °C (185 °F).
5. SDI = Silt Density Index measured according to ASTM D4189.
6. Feed and brine water must meet these ranges.
7. Only use cleaning chemicals that adhere to Toray's technical bulletins.
8. The ratio at last element.
9. This figure is reducible when there is less possibility of fouling and scaling.
10. Element(s) must be cleaned when the pressure drop increases to 1.5 times of initial value.
