Description
The ESPA1 membrane has the same chemical composition as the ESPA2 membrane, but has a higher permeability. The ESPA1 membrane requires lower supply pressures than ESPA2 and has lower energy consumption.
ESPA1 is widely used in the treatment of low TDS waters to produce drinking water.
The ESPA1 membrane is available in 4.0 and 8.0 inch diameters. A 4.0-inch diameter diaphragm is available in Low Differential LD™ technology. For more information on LD features and benefits, see the ESPA2-LD membrane page.
