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

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

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

ESPA2 LD has minimized biofouling, minimized colloidal fouling and enhanced cleanability

Highest productivity & rejection with next-generation performance

Provides a new option for communities where boron levels are naturally high or for manufacturers challenged by boron contamination issues

Increased active surface area for higher flux and rejection, with the same superior boron rejection as the ESPAB

The growing family of ESPA (Energy-Saving Polyamide) RO membranes continue to meet the ever-increasing demands of the water treatment industry. Industrial users worldwide have made ESPA their first choice for high productivity and salt rejection.

There's an ESPA solution to satisfy even the most challenging water treatment needs with exceptional performance, productivity and savings.
