Low Energy/High Flow Tap & Brackish Water Thin Film Membranes. 

The growing family of ESPA (Energy-Saving Polyamide) RO membranes continue to meet the ever-increasing demands of the water treatment industry. Industrial users worldwide have made ESPA their first choice for high productivity and salt rejection.  There's an ESPA solution to satisfy even the most challenging water treatment needs with exceptional performance, productivity and savings.

High Rejection Tap & Brackish Water Thin Film Membranes

When high performance counts, CPA membranes from Hydranautics set the standard for RO membrane elements.  CPA membranes provide the highest salt rejection rates available - every element on every order for every customer.

Seawater Membranes

Hydranautics has over two decades of experience in desalination and over 1.7 million cubic meters (461 million gallons per day) of seawater treated by their SWC (seawater composite) membranes. SWC seawater desalination membranes are available in  8-inch and 4-inch elements. Membrane formulations are designed to accommodate varying levels of seawater salinities worldwide with reliable field-proven performance.

Low Fouling Membranes

Hydranautics' LFC  (Low Fouling Composite) membranes offer breakthrough technology in the treatment of difficult feedwaters and municipal wastewater.  This membrane is well suited for the treatment of difficult feed waters for numerous municipal and industrial applications, which up to now required significant feed water pretreatment upstream of any composite reverse osmosis membrane.

Nanofiltration Membranes

ESNA series membranes are high performance nanofiltration membranes ideal for softening applications and the removal of pesticides, bacteria or viruses. They provide 50%-90% salt rejection with ultra-low-pressure operations, increased energy savings, and significantly lower installation and operating costs.
