Hydranautics
ESPA4 MAX

Details:

The Hydranautics ESPA4 MAX 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.

The MAX variant have 440 sq. ft. of active membrane surface area that reduces capital costs by requiring fewer pressure vessels and less floor space.

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.
