    HYDRAcap™ series

    by NX Filtration
    Hollow fiber ultrafiltration membranes
    Clean water
    for all
    NX Filtration produces advanced
    hollow fiber membrane modules
    for nanofiltration, ultrafiltration
    and microfiltration applications.
    As part of our ultrafiltration of-
    fering, we supply the HYDRAcap™
    series for various applications.

    HYDRAcap™ is used to treat surface


    water, ground water, seawater and
    wastewaters as either primary treat-
    ment or as pretreatment to spiral
    wound reverse osmosis (RO) and
    nanofiltration (NF). Compared to con-
    ventional pretreatment, HYDRAcap™
    allows for higher fluxes for RO and
    NF systems while extending intervals
    between cleanings. In some cases, it
    replaces conventional pretreatment
    for potable applications, ground water
    recharging and water recycling.

    RO Plant, U.A.E.

    Start-up date: May 2014

    24 racks of 120 HYDRAcap™60 modules (2,880


    in total) are producing 61 mgd (228 Ml/d) from
    an open intake sea water. UF membranes didn’t
    receive CIP until 2017 and are delivering directly
    in line high quality permeate water to 8 trains of
    SWC5 membranes.
    Operations of HYDRAcap™
    The filtration mode of HYDRAcap™
    modules is inside-out: feed water flows
    from the inside of the fibers to the
    outside. For backwashing, permeate
    is forced through the fibers in reverse Our HYDRAcap™ is a robust and low
    fouling hydrophilic polyethersulfone
    flow, from the outside to the inside,
    membrane, tolerant to chlorine,
    such that accumulated solids are peroxide and other oxidants
    removed from the fibers. resistant to pH extremes. It exhibits
    5 log (99.999%) removal for
    bacteria, giardia, cryptosporidium
    and 4 log removal for viruses.
    Turbidity is reduced to < 0.07 NTU
    and HYDRAcap™ modules benefit
    from low pressure operation, either
    in dead-end mode or cross-flow.

    Benefits

    pressure resistant

    Low 5 Log

    Advantages of
    hollow fiber technology
    Better permeate quality
    Significantly better permeate quality
    when compared to conventional pre-
    treatment, exhibiting 100% removal
    Sustainability
    of colloidal material. Permeate qual-
    ity is stable regardless of feedwater Considerably reduces the use of
    variation. predetermined chemicals. Backwash
    disposal is less problematic due to
    lower wastewater volumes.

    Improved RO performance
    Increased efficiency of RO mem-
    brane system design and operation,
    contributing to reduced capital and
    operational costs. Maximizes RO
    performance by allowing elements
    to operate longer with less cleaning.
    NX Filtration,
    your membrane partner
    NX Filtration offers a wide range of advanced
    hollow fiber membrane modules for nanofiltration,
    ultrafiltration and microfiltration applications.

    We have developed a worldwide unique


    nanofiltration concept, designed to remove organics
    from water in one single step: energy efficient,
    without extensive pretreatment and without the use
    of chemicals.

    Our ultrafiltration membranes are the best


    choice for the removal of small particles, bacteria
    and viruses from water. The HYDRAcap™ series
    is complementary to our existing range of
    ultrafiltration membrane modules.

    Our microfiltration membranes are ideally suited for


    Pilots
    high quality – low energy clarification of beverages, The complete range of our membranes
    such as wine and beer, as well as for dairy and is also available in laboratory and pilot
    pharmaceutical applications. scale modules that can be used in pilot
    installations, ranging from lab-scale
    to full-scale pilots. This provides the
    opportunity to perform a quick filtration
    and fouling test and select the best
    membranes for your application.
