ESNA, NANO and HYDRACoRe Nanofiltration Membrane (NF)

Nanofiltration Membrane ESNA

Discover Hydranautics’ ESNA nanofiltration membranes, designed with the latest technology to deliver exceptional ultra-low pressure performance. These membranes are ideal for water softening and pesticide and pathogen removal applications, with 91% to 99% salt rejection.

ESNA membranes also remove iron and Total Organic Carbon (TOC), allowing the passage of monovalent ions such as sodium and chloride. This makes them the preferred choice for municipal drinking water systems. Hydranautics’ advanced technology and the unique characteristics of ESNA membranes help achieve significant savings in operating costs and energy.

The ESNA1-LF-LD membrane is a high performance nanofiltration membrane ideal for water softening applications and removal of pesticides, bacteria and viruses. It offers 50% to 90% salt rejection with ultra-low pressure operations, increased energy savings and significantly lower installation and operating costs. It uses patented Low Differential LDTM technology designed to minimize colloidal scale formation.

The ESNA1-LF2-LD membrane is a high flux nanofiltration membrane that provides superior Natural Organic Matter (MON) rejection and moderate hardness rejection, operating at pressures below 100 psi. This translates into cost and energy savings. It also uses patented Low Differential LDTM technology designed to minimize colloidal scale formation.

The ESNA4-LD membrane offers selective separation capability using nanofiltration technology to deliver high quality permeate water while removing specific contaminants such as nitrates and larger organic compounds in low salinity waters. This membrane is especially useful in the treatment of groundwater used by agricultural communities and in the removal of sulfates in wastewater from the mining industry.

NANO-SW Nanofiltration Membrane: Advanced Solutions for the Oil & Gas Industry

Discover the NANO-SW nanofiltration membranes, specially designed for the oil and gas industry. These high-performance membranes offer selective sulfate removal, thus reducing the risks of fouling and souring in the reservoir when seawater is injected into oil reservoirs for secondary production on offshore platforms.

NANO-SW membranes reject 99.8% of sulfates while allowing the passage of other ions, especially monovalent ions such as chloride and sodium. This allows for ultra-low pressure operations, improving efficiency and reducing operating costs.

These membranes use patented Low Differential LD™ technology, designed to minimize colloidal scale formation. In addition, NANO-SW membranes feature a patented 34 mil thick feed separator that prevents the formation of colloidal scale and increases the effectiveness of membrane cleaning, resulting in lower differential pressure.

Thanks to these features, NANO-SW membranes do not require frequent cleaning, which reduces treatment costs and offers greater durability and consistent performance.

NANO-SW membranes are recognized worldwide for their high sulfate rejection characteristics in seawater injection applications in the oil and gas industry. They also provide optimum hardness rejection in water softening applications, making them an efficient and reliable solution.

HYDRACoRe® Nanofiltration Membrane: Advanced Technology for Color Removal in Drinking and Industrial Water

Discover Hydranautics’ HYDRACoRe® (Hydranautics Color Removal) membranes, specifically designed for color removal in potable and industrial water applications. These cross-flow, spiral wound, sulfonated polyethersulfone membranes offer color reduction with minimal dissolved salt removal, making them an efficient and reliable solution.

One of the key advantages of HYDRACoRe® technology is its exceptional chlorine tolerance. These membranes can withstand up to 100 ppm of chlorine during short-term cleaning, allowing them to maintain their performance and durability in applications requiring chlorine resistance.

HYDRACoRe® nanofiltration membrane is ideal for drinking water treatment systems and industrial applications where color reduction is essential without significantly affecting the concentration of dissolved salts. This makes them perfect for wastewater treatment and resource recovery in industrial processes.
