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
