Collection: Hydranautics Membranes

Hydranautics (Nitto) Reverse Osmosis & Water Treatment Membranes

For industrial, commercial, and municipal water purification systems demanding uncompromised performance and energy efficiency, Hydranautics (a Nitto Group Company) provides some of the most advanced membrane technologies in the world. As a global leader in reverse osmosis (RO) and nanofiltration (NF) solutions, Hydranautics membranes are engineered to tackle diverse water sources, ranging from low-TDS tap water and challenging brackish water to high-salinity seawater desalination. Utilizing state-of-the-art thin-film composite polyamide materials, these spiral-wound elements deliver exceptional salt rejection rates, robust chemical tolerance, and sustained permeate flow under rigorous continuous-duty operations.

The Hydranautics lineup encompasses an extensive collection of specialized series tailored to exact application requirements and varying test pressures. The ESPA (Energy Saving Polyamide) series operates at significantly lower applied pressures to drastically reduce energy consumption without sacrificing water quality. For applications requiring maximum purity, the CPA (Composite Polyamide) series delivers industry-leading high-rejection performance for brackish water. Heavy-duty desalination facilities rely on the SWC (Seawater Composite) series for processing high-salinity feedwaters at highly elevated pressures. Many of these elements feature Hydranautics' proprietary LD (Low Differential Pressure) technology, incorporating a specialized 34-mil feed spacer design to minimize colloidal fouling, reduce biological growth, and decrease the frequency of Clean-In-Place (CIP) maintenance cycles. Designed to fit standard commercial pressure vessels, these membranes ensure maximum operational uptime and pristine permeate quality across a broad spectrum of demanding treatment environments.
