RO Membranes

Perfecting Performance

Quality and performance are the mainstays of our products; we perform stringent testing for quality assurance and high performance to optimize our products for enhanced productivity and efficiency. Browse through the element specification sheets to learn the optimal range of parameters for streamlining your system.

Reverse osmosis is a process that removes particles having with a molecular weight cutoff of 100 to 200. This process is perfect for removing substances such as: metal ions, acids, sugars, dyes, natural resins and ions. Hydranautics’ RO membrane offers various degrees of flux and rejection characteristics, specifically suited to treat multiple and diverse water treatment applications.

CPA (Composite Polyamide)

Ultrapure water is essential in several industrial applications. CPA RO membranes are regarded as the industry standard for all critical high purity applications – from pharmaceutical to power industry. CPA lines of spiral-wound RO membranes are available in a variety of sizes and deliver unmatched performance with the highest salt rejection rates.

Setting the industry standard for the highest salt rejection rates

Ultrapure water is essential in several industrial applications. CPA RO membranes are regarded as the industry standard for all critical high purity applications – from pharmaceutical to power industry.

 

CPA lines of spiral-wound RO membranes are available in a variety of sizes and deliver unmatched performance with the highest salt rejection rates for brackish water applications. High throughput, efficiency and cost-effectiveness make CPA membranes the best high-rejection brackish water RO membranes in the industry.

 

Because of its exceptionally high salt rejection, CPA membranes are used in power generation, pharmaceutical, electronics and semiconductor industry.

ESPA (Energy Saving Polyamide)

Energy required to pressurize RO feed water is the largest contributor to the total energy consumption of the RO plant. As a result, chlorine tolerant membranes have helped the membrane technology become affordable and cost effective by reducing energy consumption required to operate RO system. ESPA membranes are the choice for applications demanding high-energy efficiency, with uncompromised productivity and salt rejection.

Combining energy efficiency with high rejection

The energy required to pressurize RO feed water is the largest contributor to the total energy consumption of the RO plant. ESPA membranes are the choice for applications demanding high-energy efficiency, with uncompromised productivity and salt rejection. Operating at significantly lower pressures, ESPA elements produce high quality water in a range of water treatment applications, ensuring energy cost savings.

 

ESPA membranes are used in the treatment of drinking water, industrial process waters, municipal and industrial waste water recovery and reuse because of this exception performance capability. These membranes also serve as part of polishing units in seawater desalination plants when boron rejection is critical.

LFC (Low Fouling Composite)

LFC3-LD from the LD Technology™ innovative low fouling membranes combines the attributes of a neutrally charged surface with hydrophilicity to achieve the lowest organic and colloidal fouling in the most demanding feed water conditions. Combining the attributes of a neutral surface charge and hydrophilicity, LFC3-LD provides significant reduction in fouling rates increasing the membrane’s efficiency by restoring nominal performance after cleaning.
