Operating Limits

• Typical Operating Pressure: 30 - 120 psi (2.1 - 8.3 bar)
• Maximum Operating Pressure: 140 psi (9.7 bar)
• Operating Temperature Range: 41 - 140°F (5 - 60°C)
• Cleaning Temperature Range: 105 - 185°F (40 - 85°C)
• Allowable pH - Continuous Operation: 2.0 - 10.0
• Allowable pH - Clean-In-Place (CIP): 1.8 – 12.5
• Permeate Pressure: Should not exceed baseline (concentrate) pressure at any time. Reverse pressure will damage the membrane.

Mechanical / Hydraulic

Design Pressure Drop below 140°F (60°C)

• Pressure Drop Per Element:
  • N spacer: 12-15 psi (0.8-1.0 bar)
  • V spacer: 15-20 psi (1.0-1.4 bar)
  • H or F spacer: 15-25 psi (1.0-1.7 bar)
• Pressure Drop Per Vessel (3 in series):
  • N spacer: 36-45 psi (2.5-3.1 bar)
  • V spacer: 45-60 psi (3.1-4.1 bar)
  • H or F spacer: 45-75 psi (3.1-5.2 bar)
• Pressure Drop Per Vessel (4 in series):
  • N spacer: 48-60 psi (3.3-4.1 bar)
  • V spacer: 60-68 psi (4.1-4.7 bar)

Maximum Pressure Drop above 140°F (60°C)

• 10 psi (0.7 bar) per element for N and V spacers
• 15 psi (1.0 bar) per element for H and F spacers
• Maximum differential pressure per element at temperature higher than 140°F (60°C) is 10 psi (0.7 bar) for all feed spacers.

Nominal Dimensions

Feed Water

• Pure Water Flux: 1.0-2.2 gfd/psi (24-53 l/m²/h/bar) at 77°F (25°C)
• Turbidity: Maximum feed turbidity is 1 NTU.
• SDI: Maximum feed SDI is 5.0 (15-minute test).
• Chemical Exposure - Chlorine: Exposure of HpHT membrane to free chlorine or other oxidizing agents such as permanganate, ozone, bromine and iodine is not recommended. Iron or other catalyzing metals in the presence of free chlorine or hydrogen peroxide will accelerate membrane degradation.
• Chemical Exposure - Cationic Polymers and Surfactants: PES membranes may be irreversibly fouled if exposed to cationic (positively charged) polymers or surfactants. Exposure to these chemicals is not recommended and will void the warranty.
• Lubricants: For module installation, use only water or glycerin to lubricate seals. The use of petroleum or vegetable-based oils or solvents may damage the module and will void the warranty.
