HYDRACoRe® series elements for color adjustments and removal

Hydranautics’ HYDRACoRe® (Hydranautics Color Removal) membranes are sulfonated polyethersulfone-based spiral-wound, crossflow elements that can be used for potable water as well as industrial applications in which color reduction with minimal removal of dissolved salts is desired. The key advantage of the HYDRACoRe® technology is the membranes’ superior chlorine-tolerance ( up to 100 ppm chlorine during short term cleansing)

Consistently delivering exceptional performance

ESNA membranes by Hydranautics are designed using the latest technology and exhibit unparalleled performance at ultra-low pressures. Ideal for softening applications and removal of pesticides and pathogens, ESNA membranes provide 91%-99% salt rejection.
ESNA membranes also remove iron and TOC (Total Organic Carbon), while allowing passage of monovalent ions like sodium and chloride. This makes them the preferred choice for municipal potable water systems. Hydranautics advanced membrane technology and unique features of ESNA membranes help achieve significant savings in operation cost and energy. This makes them these membranes the preferred choice for municipal potable water systems.

Superior concentration of high value products

Hydranautics’ 40+ years of manufacturing best high rejecting brackish water RO membranes is incorporated into making HYDRApolish elements. HYDRApolish composite polyamide reverse osmosis elements are of net wrapped, full fit design, intended for daily CIP in the dairy environment. Hydranautics has set new industry standard by manufacturing robot-based automatic rolling machines, specially designed for fabricating membrane modules of the highest quality. The result is a high level of filtration and separations performance for our customers.

Hydranautics’ auto-rolled HYDRApolish elements provide superior glue-line adhesion and strength, tighter rolling and caging, greater flow rates due to maximized effective membrane area and great structural reliability.

HYDRApolish is designed specifically for dairy process applications requiring continuous operation at high pressure, high temperature, or periodic heat sanitization at high temperature.

HYDRApolish applications

• RO permeate polishing
• Condensate polishing
• Pre-concentration of milk or whey for reducing product transport costs
• Lactose Production
• Juice concentration

Excellent concentration and de-mineralization

Hydranautics’ membrane technology experience and innovation are at the core of every DairyNF series membrane. Specifically designed for the separation of divalent anions and/or organic molecules greater than 200 Daltons from monovalent salts and lower molecular weight organics, DairyNF membranes deliver exceptional performance and value.

Superior membrane technology is the key to Hydranautics’ innovative DairyNF (Process Nanofiltration) elements.

All DairyNF membranes are manufactured using highly controlled, ISO 9001-compliant processes, ensuring the highest quality and most consistent, reliable performance available. Hydranautics has set a new industry-standard for the rolling of full-fit membrane modules: Hand-rolling of elements has been eliminated by the use of proprietary, robot-based automatic rolling machines, specifically designed by Hydranautics for fabricating membrane modules of the highest quality. The result is a higher level of filtration and separations performance for our customers.

DairyNF applications

• Whey and milk concentration
• De-salting (de-mineralization) of whey and other streams
• DP1/DP2 sugar fractionation
• Recovery of hydrolyzed proteins and enzymes

The PRO series from Hydranautics comprises elements that offer effective, integrated, site-specific ZLD / MLD solutions that are cost-effective, innovative, and sustainable. The PRO series elements are specifically designed to help companies to achieve their MLD and ZLD commitment, while using the right combination of technologies to treat a range of industrial wastewater streams.

PRO Series Innovation

The PRO series is a result of in-depth research and significant improvement in technologies which have provided great advances, e.g., enhanced rejection efficiencies, improved permeability, chemical tolerance and ion electivity, enhanced hydrophilicity, and improved mechanical properties and thermal stabilities.

True hydrophilic membrane chemistry with LD Technology

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.

The low fouling composite LFC3-LD (Low Differential Pressure) provides a neutral surface charge that reduces fouling when treating wastewater and surface water with high fouling potential. With the low fouling LD Technology, the differential pressure gets reduced lowering the biological and colloidal fouling inside the membrane, and successfully reducing the number of cleanings required!

LFC3-LD membrane is available in diameters of 4.0 and 8.0 inches.
