ESPA - Hydranautics - #1

ESPA - Energy Saving Polyamide Membrane Elements

Hydranautics offers a complete line of energy saving polyamide ESPA reverse osmosis (RO) membrane elements for a wide range of water treatment applications, including: the treatment of well, surface or wastewater with high salt rejection require­ments, high purity industrial applications, and seawater desalination plants requiring high boron rejection. Hydranautics has several installations around the world for these and other applications that combine their patented RO, NF, UF, and MF membrane technologies to create the perfect water treatment solution for their customer. One example is a large seawater RO plant on an island country in the Mediterranean that uses the combination of SWC5 and ESPA-B in the unique Hydranau­tics process - Integrated Membrane Solutions ® (IMS). The high performing SWC5 is ideal for use with ESPA-B membranes in the second pass in seawater and brackish water reverse osmosis plants that have stringent boron rejection requirements.

Energy Saving ESPA elements are available from Hydranautics in both 4-inch and 8-inch diameters by 40-inch long spiral wound configurations for many water treatment applications. Smaller diameter elements are also available from Hydranau­tics'licensed manufacturer Oltremare, located in Fano, Italy.

ESPA's unparalled performance characteristics can provide a significant cost savings due to the lower operating pressures required, while still providing optimal flow as well as high salt & boron rejection.

ESPA1

The world's leading high productivity, energy-saving polyamide membrane

ESPA2

ESPA2 combines high productivity, energy savings and less salt passage all in one element

ESPA2+

Offers the same rejection characteristics as ESPA2 but with even higher flow rates

ESPA2-365 f

Ideal for industrial applications

ESPA3

One of the industry's leading brackish water RO elements ESPA4

Highest productivity & rejection with next-generation performance ESPA-B

Treat water challenged with naturally occurring high boron levels or groundwater contaminated with boron from manufacturing. ESPA-B is the highest boron rejecting, low pressure element in the industry.
