ESPA2 MAX Hydranautics Membrane
Hydranautics RO Membrane Elements
ESPA® Ultra Low Pressure Membrane
ESPA2 MAX membrane element featuring high productivity (12,000 gpd) and high rejection (99.6%) in factory test conditions. Element has 440 ft2 of 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 available.
Hydranautics’ line of ESPA products are widely acclaimed for their effectiveness among a wide variety of water treatment applications, for working at a remarkably low operating pressures, providing higher flows, and saving more energy than any other membrane type.
