    Hydranautics CPA (composite polyamide) membrane elements have become the trusted industry standard for high performance, high purity applications. CPA elements are available in both 4-inch and 8-inch diameters by 40-inch long spiral wound configurations as well as smaller diameter and shorter length elements for all high purity applications. CPA membranes provide some of the highest salt rejection rates available - every element on every order for every customer.

    Hydranautics also offers Integrated Membrane Solutions (IMS) combining a range of RO, NF, UF and MF membrane technologies to achieve the most comprehensive, effective, low-cost solutions for the industry.

    High performance energy saving ESNA nanofiltration membrane elements are ideal for softening applications and the removal of pesticides, pathogens, bacteria or viruses. They provide 50% - 90% salt rejection with ultra-low-pressure operations, increased energy savings, and significantly lower installation and operating costs. They can effectively remove organics which can form disinfection by-products in municipal water distribution lines.

    Maximum Performance, Optimal Solution

    HYDRAcap® MAX is used to treat a wide range of highly variable waters as either primary treatment or as pretreatment to reverse osmosis (RO) and nanofiltration (NF). Compared to conventional pretreatment, the HYDRAcap® MAX offers the combined benefits of high recovery and low footprint requirement due to its optimized membrane area and novel cleaning regimes. High strength PVDF membrane minimizes fiber breakage rate and ensures consistently superior filtrate quality, which enables RO and NF systems to be operated at higher fluxes, while maintaining longer intervals between cleanings.

    Membrane Bio Reactor (MBR) is a hybrid wastewater treatment technology that combines biological treatment by activated sludge and physical treatment by membrane filtration. Compared to conventional activated sludge treatment, MBR and particularly HYDRAsub® produces high quality permeate water suitable for RO treatment and reduces drastically footprint by elimination of sedimentation tank and operation at higher Mixed Liquor Suspended Solids (MLSS).

    Hydranautics HYDRACoRe® (Hydranautics Color Removal) membranes are sulfonated polyether sulfone-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. For example, HYDRACoRe® membranes tolerate up to 100 ppm chlorine during short term cleansing.
