Since its founding in 1963, Hydranautics has been committed to the highest standards of technology research, product excellence and customer satisfaction. Hydranautics entered the reverse osmosis (RO) water treatment field in 1970, and is now one of the most respected and experienced firms in the membrane separations industry. Hydranautics became part of the Nitto Group when it was acquired in 1987. Hydranautics corporate headquarters is located in the city of Oceanside, California in a 160,000 ft2 (14,684 m2) manufacturing facility residing on 14 acres, all owned by Hydranautics. Mebranes are available in 4040 and 8040 sizes.

The workhorse and industry standard, CPA2 delivers consistently high performance, day in and day out.

The element with the best combination of productivity and salt rejection available.

CPA5-LD has minimized biofouling, minimized colloidal fouling and enhanced cleanability

The world’s leading high productivity, energy-saving polyamide membrane

Offers the same rejection characteristics as ESPA2 but with even higher flow rates

ESPA2 LD has minimized biofouling, minimized colloidal fouling and enhanced cleanability

Provides a new option for communities where boron levels are naturally high or for manufacturers challenged by boron contamination issues

Increased active surface area for higher flux and rejection, with the same superior boron rejection as the ESPAB

The Low Fouling Composite LFC3-LD (Low Differential pressure) reduces fouling in wastewater and in surface water with high fouling potential for reuse and reclaim applications.

The highest boron rejection available

Ten percent additional active surface area and exceptional boron rejection

Ten percent additional active surface area and superior boron rejection

Lower fouling for maximum performance

Ten percent additional active surface area and flow and superior boron rejection
