Hydranautics ESPA2-LD-4040 Reverse Osmosis Membrane 4"x 40"
The energy required to pressurize RO feed water is the largest contributor to the total energy consumption of the RO plant. ESPA membranes are the choice for applications demanding high-energy efficiency, with uncompromised productivity and salt rejection. Operating at significantly lower pressures, ESPA elements produce high-quality water in a range of water treatment applications, ensuring energy cost savings. ESPA membranes are used in the treatment of drinking water, industrial process waters, municipal and industrial wastewater recovery and reuse because of this exceptional performance capability.
These membranes also serve as part of polishing units in seawater desalination plants when boron rejection is critical. 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. These membranes offer consistently low feed pressures and longer intervals between cleanings
