Hydranautics – ESPA membrane
ESPA® (Energy Saving Polyamide) elements achieve high flux/lower pressure without compromising standards for high rejection. Since
its introduction in the late 1990s, the ESPA® membrane has gained wide acceptance in the water treatment industry due to the
significant operational cost savings associated with their use. 4” and 8” configurations are available.
Up to 99.6% nominal rejection
Lower pressure for lower CAPEX/OPEX
Municipal potable and wastewater plants
ESPA1, ESPA2, ESPA2 MAX, ESPAB (high boron rejection), ESPAB MAX, ESPA2-LD (low colloidal and biological fouling), ESPA4
