Operating limits

Recommended design conditions:

• Feed Water Pressure: <1.0 MPa (150 psi)
• Feed Water Temperature: <35 °C (95 °F)
• Feed Water Turbidity (SDI): <4 (measured according to ASTM D4189)

• Maximum Feed Water Temperature: 40 °C (104 °F)

General operating notes:

• If operated outside the recommended design range, the effective membrane life may be reduced.
• High flux operation on 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 of initial value.
• Sterilization must follow guidances in Toray's technical bulletin.
