    Dupont Filmtec™ High-Performance Membranes

    Product Description: DuPont™ Filmtec™ membranes provide reliable and efficient solutions for industrial users, helping to solve challenging water treatment problems (water reuse and near-zero liquid discharge).

    Filmtec Membrane Series: CR100, XC70, XC-N, XUS180808

     

    The DuPont Filmtec CR100 membrane element is an ultra-low-pressure, anti-fouling reverse osmosis membrane element that resists biological and organic fouling, has good cleaning performance, low energy consumption, and high solute rejection rate.

    Features and Advantages:

    ◆ CR100 desalination rate 99.7%, while ordinary membranes 99.5%

    ◆ Reduced cleaning frequency, up to 50% reduction

    ◆ PH tolerance range 1-13, contributing to the most effective cleaning of biofilms, organic compounds and inorganic salt scaling

    ◆ Energy saving up to 10% with the same water production

     

     

    ✔DuPont Filmtec XC70 membrane elements can concentrate the concentrate water TDS to around 70000ppm, maximizing the reverse osmosis recovery rate

    Features and Advantages:

    ◆ High desalination rate, anti-fouling, stable membrane performance

    ◆ Easy-to-clean, low-pressure drop element structure

    ◆ Advanced membrane manufacturing process that completely eliminates the need for chlorination

     

     

    ✔ DuPont Filmtec XC-N membrane elements help industrial users convert most of the reverse osmosis concentrate into a pure, more easily crystallizable salt solution, reducing concentrate wastewater and lowering near-zero discharge energy consumption.

    Features and Advantages:

    ◆ High selectivity, high monovalent ion permeability, and high divalent ion and COD retention rate,

    Helps to separate high-purity salt solution while reducing concentrate wastewater

    ◆ Used for zero discharge salt separation, NaCl purity up to 99% or more

    ◆ Using high-permeability membrane chemistry technology to improve water recovery rate and reduce energy consumption

    ◆ The membrane has stable and reliable long-term performance

     

    ✔ UHP RO membrane: XUS180808 (near-zero discharge field)

    A: Features of ultra-high pressure reverse osmosis membrane elements:

    Unique and innovative design, mature and reliable spiral wound reverse osmosis membrane technology

    ◆ High-pressure resistant

    ◆ Anti-fouling

    Through improvements to the mature traditional spiral wound membrane process, the maximum operating pressure can reach 120 bar, and it has passed extreme pressure and temperature tests

    B: Standardized elements, suitable for standard system device design, greatly reducing system costs

    ◆ Low investment cost

    ◆ Low operating cost

    C: Ultra-high pressure reverse osmosis membrane elements are available in 8, 4 and 2.5 inch specifications for customers to choose from

    ◆ Inlet flow path 34mil, stable desalination rate 99.7%

    D: Application areas

    DuPont ultra-high pressure reverse osmosis is mainly used for the treatment of concentrated salt wastewater and near-zero discharge

    ◆ Thermal power generation industry (desulfurization wastewater, circulating cooling water, sewage wastewater)

    ◆ Metallurgy and hydrometallurgy (mining tail water, mine wastewater, hydrometallurgical wastewater)

    ◆ Chemical and petrochemical industry (coal chemical wastewater, chemical wastewater, refinery wastewater)

    ◆ Oil and gas exploration industry (oilfield produced water, coalbed methane wastewater)

    ◆ Concentration of salt-containing liquids and special liquids

    E: We can provide overall solutions, including UF, RO, NF and UHP RO DuPont ultra-high pressure reverse osmosis membrane elements
