Hydranautics ESPA (Energy Saving Polyamide) Membrane Elements

Combining energy efficiency with high rejection

The energy required to pressurize RO feed water is the largest contributor to the total energy consumption of the RO plant. Hydranautics 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 ESPA membranes are used in the treatment of drinking water, industrial process waters, municipal and industrial waste water recovery and reuse because of this exception performance capability. Hydranautics ESPA membranes also serve as part of polishing units in seawater desalination plants when boron rejection is critical.
