Hydranautics CPA2-4040 High Rejection Membrane

The workhorse and industry standard, CPA2 delivers consistently high performance, day in and day out. When high performance counts, CPA membranes from Hydranautics set the standard for RO membrane elements. CPA membranes provide the highest salt rejection rates available - every element on every order for every customer.

CPA2-4040 Specifications:

• Permeate Flow: 2,250 gpd (8.5m3/d)

• Salt Rejection : 99.5% (99.2% minimum)

• Configuration: Spiral Wound

• Membrane Polymer: Composite Polyamide

• Membrane Active Area: 85ft2 (7.9m2)

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

• 1500 PPM NaCl solution

• 225 psi (1.55 MPa) Applied Pressure

• 77°F (25°C) Operating Temperature

• 15% Permeate Recovery

• 6.5 - 7.0 pH Range

Standard Operating Limits:

• Maximum Applied Pressure: 600 psig (4.16 MPa)

• Maximum Chlorine Concentration: < 0.1 PPM

• Maximum Operating Temperature: 113°F (45°C)

• pH Range, Continuous (Cleaning): 2-10 (1-12)

• Maximum Feedwater Turbidity: 1.0 NTU

• Maximum Feedwater SDI (15 mins): 5.0

• Maximum Feed Flow: 16 GPM (3.6 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.
