Hydranautics CPA2 RO Membrane: 8" x 40"
(Suggested alternative: Filmtec BW30-365)
CPA (Composite Polyamide) elements set the standard for RO membrane elements - over 600 million gallons per day of pure water
are produced by CPA elements for global municipalities and industries. 4" and 8" configurations available.
Advantages
- 99.7% nominal rejection
- High TOC, silica and hardness rejection
Applications
- Desalting of well waters - municipal drinking water
- Reducing TDS prior to ion exchange
- Boiler make-up water
- Ultrapure water for semi-conductor manufacture
Performance
- Permeate Flow: 10,000 gpd (37.9m3/d)
- Salt Rejection: 99.7% (99.5% minimum)
Application Data
| 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) | 2-10 (1-12)* | | 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 | 15 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
