🏢 Hydranautics CPA2-8 High Rejection RO Membrane
The Hydranautics CPA2-8 is an 8-inch high-rejection reverse osmosis element that serves as a trusted industry standard for high-purity water applications. Engineered for the treatment of brackish water, this second-generation CPA (Composite Polyamide) membrane is a robust "work-horse" product, delivering exceptionally high salt rejection rates of 99.7%. It is specifically designed for critical processes where low TDS permeate is essential, such as municipal drinking water production, semiconductor manufacturing, and boiler feed water for power plants.
The CPA2-8 features a durable 34-mil feed spacer that optimizes hydrodynamics and enhances the element's resistance to biological and colloidal fouling. With an active membrane area of 365 square feet, this element provides a reliable permeate flow of 10,000 gallons per day. Its consistent performance and ability to reject high levels of TOC, silica, and hardness make it an ideal choice for facility managers looking to reduce overall operational costs and extend the intervals between chemical cleanings in high-purity systems.
