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 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.
ESPA4 membranes require ultra-low pressures without compromising standards for high flux and high salt rejection. ESPA4 membrane has been commonly used in drinking water production from well and surface waters in the water treatment industry. It is widely accepted due to significant operational cost savings associated with their use. Due to their ultra-low feed pressure requirement, ESPA4 membranes have been accepted as a standard in the second pass of a two pass reverse osmosis systems.
