CPA7 MAX Hydranautics Nitto Membranes

Hydranautics CPA7 MAX Brackish Water RO Membrane

For industrial operations such as semiconductor manufacturing, power generation, and pharmaceutical production, consistently producing ultra-high purity water is critical to daily success. The Hydranautics CPA7 MAX is a commercial-grade, brackish water reverse osmosis (RO) membrane engineered explicitly to meet the most stringent water quality demands. Utilizing advanced composite polyamide technology, this 8-inch by 40-inch element offers the highest salt rejection available in the industry. Built for heavy-duty, continuous operation, it ensures the reliable removal of dissolved solids, TOC, boron, and silica, providing large-scale industrial and municipal water treatment setups with an exceptional level of water purity.

Under the hood, this membrane is designed to maximize both productivity and system footprint efficiency. It features an expansive 440 square feet of active membrane area, which allows operators to generate greater output while reducing capital costs by requiring fewer pressure vessels. Operating efficiently at a standard applied test pressure of 225 PSI, it delivers a massive permeate flow rate of 12,600 gallons per day (GPD) alongside an outstanding stabilized salt rejection rate of 99.8%. Built to withstand rigorous operational demands, it safely handles a maximum applied pressure of up to 600 PSI, a maximum feed flow rate of 75 GPM, and continuous liquid temperatures up to 113°F (45°C), providing an optimal balance of robust durability and ultra-pure water production.
