Hydranautics ESPA4-LD HP Reverse Osmosis Membrane 8" x 40"
ESPA4 are the lowest feed pressure membranes offering low energy consumption. ESPA4 membranes require ultra-low pressures without compromising high salt rejection and are commonly used in the second pass of a reverse osmosis system.
Low differential LD Technology® models are offered to minimize colloidal fouling when used with conventional pre-treatment equipment. These membranes offer consistently low feed pressures and longer intervals between cleanings.
ESPA4-LD HP is high flux membranes offering low energy consumption without compromising on high rejection. These membranes have an active membrane area of 400 ft2 (37.2 m2), 34 mil brine spacer thickness, and high pressure construction for operation up to 1200 psi (8.27 MPa) to allow greater concentration of feed solution.
Typically used in the treatment of drinking water, industrial process waters, municipal and industrial waste water recovery and reuse because of this exceptional performance capability.
