Hydranautics ESPA2 MAX Reverse Osmosis Membrane 8" x 40"
ESPA2 membranes provide optimum salt rejection and permeate flows. They are chosen when lower permeate TDS and lower feed pressures are needed. ESPA2 membranes offer the highest energy efficiency at the lowest costs and are used in large municipal wastewater reclamation plants.
ESPA2 membranes are available in the MAX variant with 440 ft2 (40.9 m2) active membrane surface area. Increased membrane area reduces capital costs by requiring fewer pressure vessels and less floor space.
ESPA membranes are used in the treatment of drinking water, industrial process waters, municipal and industrial waste water recovery and reuse because of this exception performance capability. These membranes also serve as part of polishing units in seawater desalination plants when boron rejection is critical.
