A New Generation of ESPA Performance

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

ESPA1, ESPA2, and ESPA3 have long been the industry leaders, with the highest productivity and rejection available, producing up to 14,000 GPD.

Hydranautics’ ESPA4 low energy membrane delivers even greater productivity and rejection, now at operating pressures of less than 100 psi. Enjoy up to 250% greater productivity per membrane area compared with conventional polyamide membranes, at the lowest cost per gallon produced.

There’s an ESPA solution to fit even the most demanding water treatment needs – now with greater performance, productivity and savings.
