ESPA

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

Ideal for 2nd pass industrial applications

ESPA3

One of the industry's leading brackish water RO elements

ESPA4

Highest productivity & rejection with next-generation performance

ESPA-B

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

A New Generation of ESPA Performance

The growing family of ESPA (Energy-Saving Polyamide) RO membranes continue 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.

Hydranautics' newer ESPA-B membranes provide 8,600 gallons per day (32.6 m3/d) of flow at 99.2% nominal salt rejection and 96% boron rejection, the new ESPA-B (B for Boron Rejection) is the highest boron rejecting, low pressure element in the industry.

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

MODELS AVAILABLE ON STOCK:
ESPA 3 4040, ESPA 4 4040

ESPA 8040 MODELS



CPA

CPA2

The workhorse and industry standard, CPA2 delivers consistently high performance, day in and day out

CPA3

The element with the best combination of productivity and salt rejection available

CPA4

For applications where the highest salt rejection is required


High Performance for the highest quality water

When high performance counts, CPA membranes from Hydranautics set the standard for RO membrane elements. Over a half-billion gallons per day of pure water are produced by CPA2 for the world's industries, and for municipal supplies around the globe.

CPA3 and CPA4 offer even higher salt rejection rates. Semiconductor manufacturers rely on Hydranautics to provide the ultrapure water needed for the production of sensitive semiconductor chips. And because of their high TOC, silica and hardness rejection, CPA3 and CPA4 are ideal for producing low-scaling boiler make-up water for power generation applications. CPA membranes ensure reduced maintenance and more efficient power plant operation, while significantly reducing downstream ion exchange costs.

CPA membranes provide the highest salt rejection rates available - every element on every order for every customer.




SWC

SWC3

High performance membrane for seawater desalting

SWC3+

Designed and engineered to meet your most demanding desalination needs

SWC4+

High temperature, high rejection performance in a high surface area membrane

SWC5

Designed to offer the perfect combination of high flow, and superior salt and boron rejection with low operating pressures.

The first choice in seawater desalination

Hydranautics has over two decades of experience in desalination and over 1.27 million cubic meters (337 MGD) per day of seawater treated by their SWC (seawater composite) membranes. With more installed capacity than any other competitor, the SWC membrane provides unparalleled and consistent operating performance.

SWC seawater desalination membranes range from high productivity 8-inch and 4-inch elements, all offering the highest levels of salt rejection and a consistently pure end product. Membrane formulations are designed to accommodate varying levels of seawater salinities worldwide with reliable field-proven performance.
 



ESNA

ESNA1-LF-4040/ESNA1-LF

Significantly reduces operating costs and provides optimum hardness rejection for softening applications, available in 4-inch and 8-inch diameter configurations

ESNA1-LF2

Designed to provide high rejection of natural organic materials and moderate rejection of total hardness, while running below 100 psi, offering energy and cost savings.

A New Generation of ESNA Performance

ESNA1-LF are high performance nanofiltration membranes ideal for softening applications and the removal of pesticides, bacteria or viruses. They provide 50%-90% salt rejection with ultra-low-pressure operations, increased energy savings, and significantly lower installation and operating costs.
