Hydranautics RO Membranes / Nitto RO Membranes

Hydranautics is one of the global leaders in membrane technology. We apply state-of-the-art technology to manufacture industry’s most advanced, high-performance membrane products.

Hydranautics CPA Membranes


Ultrapure water is essential in several industrial applications. CPA RO membranes are regarded as the industry standard for all critical high purity applications – from pharmaceutical to power industry. 


Hydranautics ESPA 2 LD Membranes


The energy required to pressurize RO feed water is the largest contributor to the total energy consumption of the RO plant. ESPA membranes are the choice for applications demanding high-energy efficiency, with uncompromised productivity and salt rejection. Operating at significantly lower pressures, ESPA elements produce high quality water in a range of water treatment applications, ensuring energy cost savings.


Hydranautics LFC 3 LD Membranes


LFC3-LD from the LD Technology™ innovative low fouling membranes combines the attributes of a neutrally charged surface with hydrophilicity to achieve the lowest organic and colloidal fouling in the most demanding feed water conditions. 


Hydranautics SWC Membranes


As the world is facing freshwater scarcity, Hydranautics brings a range of SWC RO membranes to meet the demands of desalination industry. SWC membranes have improved the productivity and salt rejection for more than two decades while reducing their environmental impact. SWC membranes come in a range of innovative formulations depending on the level of seawater salinity required.
