Auxicolor - Model ESPA - Energy Saving Polyamide Membrane Elements
Hydranautics offers a complete line of energy saving polyamide ESPA reverse osmosis 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 y 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 ESPAB in the unique Hydranautics process- Integrated Membrane Solutions (IMS). The high performance SWC5 is ideal for use with ESPAB membrane in the second pass in seawater and brackish water reverse osmosis plants that have stringent boron rejection requirements.
