    Seawater RO membrane LG SW400ES

    Introduction of seawater RO membrane LG SW400ES

    LG Chem’s NanoH2O™ seawater RO membranes, incorporated with innovative Thin Film Nanocomposite (TFN) technology, reduce the cost of desalination while delivering superior water quality. Our seawater RO membranes provide industry leading salt rejection and produce 20% more flow than membranes manufactured with conventional technologies. We continue to leverage the technological advantages of our seawater RO membranes to expand our market share, accruing more than 3,000 Million Liter per Day (MLD) projects for both new and replacement market since the establishment.

    LG SW ES (Energy Saving) membranes offer significant energy savings while producing good water quality; suitable for low to medium salinity seawater applications.

    Outstanding advantages of LG BW-400-ES seawater RO membrane:

    • LG Chem’s NanoH2O™ Seawater RO Membrane is currently the world’s #1 Seawater RO (SWRO) Membrane with more than 4 million m3 of water filtered from seawater every day thanks to Thin Film Nano-Composite (TFN) technology using materials nano on RO membranes enhances the membrane’s anti-scaling and desalination capabilities while having high flow and low operating pressure compared to conventional Thin Film Composite (TFC) RO membranes. This makes the processing performance as well as the membrane’s ability to operate more stable and durable.
    • The SWRO NanoH2O™ membrane also currently ranks first in desalination capacity, reaching 99.89%, a figure that no other TFC membrane has achieved.
    • High desalination capacity, high flow rate, low operating pressure are extremely important factors in a seawater treatment plant to help minimize investment costs, system size, operating costs and water quality. better with greater throughput on the same number of membranes used.

    Operating conditions of LG BW-400-ES seawater RO membrane:

    Max. Applied pressure1.200 psi (82,7 bars)
    Max. Chlorine concentration<0.1ppm
    Max. Operating temperature45°C (113°F)
    pH Range, Continuous (Cleaning)2-11 (2-13)
    Max. Feedwater turbidity< 1.0 NTU
    Max. Feedwater SDI (15 mins)<5
    Max. Feed flow75 gpm (17 m3/h)
    Min. Ratio of concentrate to permeate flow for any element5:1
    Max. Pressure drop (AP) for each element15 psi (1.0 bar)

    Factors that need to be collected to choose the right type of RO membrane:

    1. What is the input water? (Sea water, brackish water, river water, well water, city water supply water, wastewater (with or without UF pretreatment), level 1 RO water, level 2 RO water)
    2. Capacity needed to treat water per day, per hour?
    3. Main indicators of raw water quality: TDS, pH, temperature, salinity, hardness, silica…
    4. Desired water output quality? (used for what, eating or living or production?)
    5. Installation area to be able to choose membrane housing length configuration

    Select the permeate flow design capacity for each 8inch RO membrane for different types of input water:

    1. RO water: SDI (Silt Density Index) = 1, design flow 34LPH for 1m2 = 1.250m3/h
    2. Brackish water is well water: SDI (Silt Density Index) = 3, design flow 25-27LPH = 0.925-0.999m3/h
    3. Brackish water is surface water: SDI (Silt Density Index) = 5, design flow 18-21LPH = 0.666-0.777m3/h
    4. Sea water: SDI (Silt Density Index) = 5, design flow 12-13LPH = 0.444-0.481m3/h
    5. Wastewater with UF pretreatment: SDI (Silt Density Index) = 3, design flow 18LPH  = 0.666m3/h
    6. Wastewater Without UF pretreatment: SDI (Silt Density Index) = 5, design flow 15LPH = 0.555m3/h
