Hydranautics CPA5-MAX Membrane

Product Description

 

CPA5-MAX - one of the best membranes in the industry. When high performance counts, CPA membranes from Hydranautics set the standard for RO membrane elements. The CPA5-MAX has minimized biofouling, minimized colloidal fouling and enhanced cleanability. CPA membranes provide the highest salt rejection rates available - every element on every order for every customer.

CPA5-MAX Specifications

  • Permeate Flow: 12,000 gpd (45.5 m3/d)
  • Salt Rejection: 99.7% (99.6% minimum)
  • Configuration: Spiral Wound
  • Membrane Polymer: Composite Polyamide
  • Nominal Membrane Area: 440 ft2 (40.9 m2)

The stated performance is initial (data taken after 30 minutes of operation), based on the following conditions:

  • 1,500 ppm NaCl
  • 225 psi (1.55 MPa) Applied Pressure
  • 77°F (25°C) Operating Temperature
  • 15% Permeate Recovery
  • 6.5 - 7.0 pH Range

[custom-features]

Standard Operating Limits:

  • Maximum Applied Pressure: 600 psig (4.14 MPa)
  • Maximum Chlorine Concentration: < 0.1 PPM
  • Maximum Operating Temperature: 113°F (45°C)
  • pH Range, Continuous (Cleaning): 2-11 (1-13)*
  • Maximum Feedwater Turbidity: 1.0 NTU
  • Maximum Feedwater SDI (15 mins): 5.0
  • Maximum Feed Flow: 75 GPM (17.0 m3/h)
  • Minimum Ratio of Concentrate to Permeate Flow for any Element: 5:1
  • Maximum Pressure Drop for Each Element: 10 psi

The limitations shown here are for general use. For specific projects, operating at more conservative values may ensure the best performance and longest life of the membrane. See Hydranautics Technical Bulletins for more detail on operation limits, cleaning pH, and cleaning temperatures.
