CPA5-LD Hydranautics Nitto 11,000 GPD at 225 PSI 8 inch x 40 inch Membranes

Hydranautics CPA5-LD High Rejection Brackish Water RO Membrane (11,000 GPD)

The Hydranautics CPA5-LD is a high-performance 8-inch reverse osmosis element engineered for the treatment of brackish water in municipal and industrial applications. As a key member of the CPA (Composite Polyamide) family, it is specifically designed to provide ultra-high salt rejection while maintaining energy efficiency. The "LD" designation indicates the inclusion of Low Differential technology, which features a specialized feed spacer designed to minimize colloidal fouling and reduce the frequency of membrane cleanings.

Utilizing an advanced thin-film composite polyamide membrane, the CPA5-LD is ideal for producing high-purity water for applications such as power generation, semiconductor manufacturing, and boiler feed makeup. Its robust construction ensures long-term stability and consistent performance even when treating feedwater with high fouling potential. With an active surface area of 400 square feet, this element delivers a permeate flow of 11,000 gallons per day, making it a reliable solution for large-scale desalination projects requiring stringent water quality standards.
