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.

Since our inception in 1963, we are committed to the highest standards of technology research, product excellence and customer satisfaction. We entered the Reverse Osmosis (RO) membrane field in 1970 and are now one of the most respected and experienced companies in the industry. Hydranautics was acquired by Nitto Denko Corporation, Japan in 1987 and we became a part of Nitto Global Membrane Division (GMD).

The Nitto Global Membrane Division comprises of three production facilities: Hydranautics, headquartered in Oceanside, California, USA; a membrane manufacturing plant in Shiga Prefecture, Japan and an element assembly facility in Shanghai, China. These three facilities, in addition to a network of offices and warehouses spanning around the globe, provide 24/7 technical and sales support with timely response to customer requests. Our continuing commitment to research and technology results in the continued development of specialized membrane products.

Hydranautics’ products are currently in use on all seven continents. Product applications include potable water, boiler feedwater, industrial process water, wastewater treatment, surface water treatment, seawater desalination, residential water, electronic rinse water, agricultural irrigation and pharmaceuticals. Comprehensive customer service and support is available round the clock and around the world.

A network of worldwide sales offices throughout the USA, South America, Europe and Asia support Hydranautics’ global business base. Hydranautics is the first membrane manufacturer to meet the highest quality standards with ISO 9001 Quality System Certification. Both Hydranautics and Nitto take pride in setting industry standards for technical excellence and product quality, and welcome the opportunity to respond to your most challenging water treatment requirements.
 
Hydranautics’ & Nitto’s experience in membrane technology spans five decades. We remain committed to delivering innovative membrane technologies to meet the growing demand of the separation industry. As a result, we design and manufacture a broad spectrum of reverse osmosis, nanofiltration, ultrafiltration and microfiltration membranes in various configurations and chemistries.

We offer results:

Our Integrated Membrane Solution (IMS), are customized membrane solutions to meet specific business objectives and offer comprehensive technical support in the development of new technology

LD technology™ products are globally used for various applications for Brackish water, sea water desalination, waste water treatment etc. This new generation LD RO elements have been effectively used on difficult feedwater plants, including those treating reclaimed wastewater, surface water and difficult well waters
Process Separation includes reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF) as well as microfiltration (MF) membranes used in various special liquid-liquid separation applications other than waste water treatment and desalination. DairyRO is widely used in concentration of UF permeate, whey, skim milk and polishing applications.

SanRO® and SanRO®HS are specially used in pharmaceutical industry to obtain USP purified water for injection systems. Process side offers a wide variety of NF membranes including DairyNF™ and Hydracores which have a varied molecular weight cut-off ranging from 3000 Dalton to 200 Dalton. DairyNF™’s are widely used in milk and whey concentration, demineralization, sugar fractionation and various such applications where low-pressure operation and high salt passage is desired. Hydracores have specialized applications in color removal in juices, sauces, food extracts, dye and protein and enzyme concentration.

On the UF side, Hydranautics offers membranes with 5000 Dalton and 10,000 Dalton molecular weights cut off and are widely used in whey protein concentration applications. Our microfiltration membrane with a 300,000 to 500,000 Dalton molecular weight cut off is used to clarify saccharification liquor and other starch process streams.
 


DairyRO

Hydranautics’ 40+ years of manufacturing best high rejecting brackish water RO membranes is incorporated into making DairyRO elements. DairyRO composite polyamide reverse osmosis elements are of net wrapped, full fit design, intended for daily CIP in the dairy environment.



DairyNF™

Hydranautics’ membrane technology experience and innovation are at the core of every DairyNF™ series membrane. Specifically designed for the separation of divalent anions and/or organic molecules greater 200 Daltons from monovalent salts and lower molecular weight organics, DairyNF™ membranes deliver exceptional performance and value.

 


DairyUF®
Hydranautics extends its experience in membrane innovation and design to manufacture the DairyUF series elements which deliver highest quality as well as most consistent and reliable performance available. Hydranautics has set a new industry standard with automated rolling of these full-fit membrane nodules.



SuPRO

Our polysulphone MF membrane with a 300K MWCO provides high flow and rejection with excellent tensile strength. It is widely used for clarification applications especially in the sugar industry. Other applications include: clarification of enzyme streams, fruit and vegetable, juices, wine etc.



SanRO®

SanRO®and SanRO®

HS elements are USP compliant and typically used in producing purified water in pharmaceutical, medical, biotechnology, food, beverage and semiconductor processes.

Elements meet all requirements for purified water and confirm to FDA Regulation CFR, Title 21.



HYDRACoRe®

Hydranautics’ HYDRACoRe® (Hydranautics Color Removal) membranes are sulfonated polyethersulfone-based spiral-wound, crossflow elements that can be used for
potable water as well as industrial applications in which color reduction with minimal removal of dissolved salts is desired.



HYDRApro®

The HYDRApro® series is a unique set of spiral wound membranes customized specifically for industrial process applications. These membranes are based on existing

Hydranautics high-performance membrane products which have been specially designed to treat a variety of challenging industrial feed streams including high fouling, high temperature, or chemically aggressive feeds.
