Product Description

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
