Hydranautics CPA Series Membranes
When high performance counts, CPA (Composite Polyamide) 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.
Benefits
- Up to 99.7% Nominal Rejection
- High TOC, silica and hardness rejection
- High permeate flow
- High rejection of boron – up to 92%
- Lowest biological and colloidal fouling
- Greater tolerance to high pH cleanings
- Lower energy consumption
Details
CPA2 – “The Workhorse” Most widely used with consistent performance

CPA5-LD Series – New technology minimizing bio-fouling and colloidal fouling and enhancing cleanability.
Where ultrahigh purity water is required under difficult feedwater conditions, the CPA5-LD gives the most desirable combination of high rejection and high flow. For industries such as power, semiconductor, food and beverage, where high purity water is critical to operations, CPA5-LD gives you the most desirable combination of performance and efficiency. CPA5-LD helps reduce RO system power consumption and the membrane resistance to biological and colloidal fouling helps reduce the number of cleanings required, lowering the overall cost of your operation.
