• Feed Water pH: 6

Operating Limits

The recommended design range applies to operational and design conditions with minimal fouling and scaling. Operating outside this range may reduce effective membrane life.

• Recommended Design Conditions:
  • Feed Water Pressure: 3.0 MPa (430 psi)
  • Feed Water Temperature: 30 °C (86 °F)
  • Feed Water Turbidity (SDI): 4 (SDI is Silt Density Index measured according to ASTM D4189.)
  • Feed Water Chlorine Concentration: 0.1 – 0.7 mg/L (Feed and brine water must meet this range.)
  • Feed Water pH Range, Continuous Operation: 4 – 6.5 (Feed and brine water must meet this range.)
  • Feed Water pH Range, Chemical Cleaning: 3 – 8.5 (Cleaning chemicals shall follow Toray's technical bulletins.)
  • Feed Flow Rate per Vessel: 200 L/min. (52.8 gpm)
  • Brine Flow Rate per Vessel: 40 L/min. (10.6 gpm)
  • Brine/Permeate Flow Ratio: 6 (Ratio at last element. This figure is reducible when there is less possibility of fouling and scaling.)
  • Pressure Drop (per Element): 1 kg/cm² (14 psi)
  • Pressure Drop (per Vessel): 2 kg/cm² (29 psi)
• Maximum Operating Conditions:
  • Maximum Feed Water Pressure: 4.1 MPa (600 psi)
  • Maximum Feed Water Temperature: 40 °C (104 °F)
• Cleaning and Sterilization:
  • 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.
  • High flux operation on feed water turbidity greater than 3 or 4 SDI generally results in frequent cleaning requirements. Operating pressure should be selected to maintain the flux rate, or permeate flow rate per single element.

Mechanical / hydraulic

• Dimensions: The diagram illustrates the element with an overall length of 1016 mm. It indicates feed water and concentrated brine flow directions, and permeate outlet. Other marked dimensions are 11 mm and 22 mm, which likely refer to internal or connector specifications. All dimensions are shown in millimeters. See the official PDF for exact tabulated values and a detailed diagram.
