ESPA1 reverse osmosis membrane has the same chemistry as the ESPA2 reverse osmosis membrane but has a higher permeability. ESPA1 reverse osmosis membrane requires even lower feed pressures than ESPA2 and the energy consumption is also lower.

ESPA1 is popularly used in the treatment of low TDS waters to produce potable water.

ESPA1 reverse osmosis membrane is available in diameters of 4.0 and 8.0 inches. The 4.0 inch diameter membrane is available in Low Differential LD ™ technology. See ESPA2-LD reverse osmosis membrane page for more information on the LD features and benefits.
