The CTUF semi-softening membrane is an innovative filtration solution that combines the advantages of spiral-wound and tubular membranes. It delivers high throughput and strong fouling resistance while maintaining stable operation under high suspended solids loads and limited footprint conditions.
This membrane provides a cost-effective, reliable solution for various wastewater and circulating water treatment applications.
The CTUF membrane features a high-porosity structure with tightly controlled pore size distribution, enabling high flux filtration. Its hydrophilic and oil-repellent surface resists fouling from oils and contaminants.
By combining crossflow or semi-softening tubular design, water is distributed evenly across the membrane surface, minimizing scaling and concentration polarization. This enhances water production efficiency and simplifies cleaning.
l Oil Resistance: Handles feedwater with oil content up to 150 ppm.
l High Temperature Tolerance: Operates reliably up to 50 °C.
l Acid and Alkali Resistance: Compatible with pH range 1–13.5.
l Fouling Resistance: Reduces chemical usage and minimizes cleaning wastewater.
l High Precision Filtration: Uniform pore size ensures consistent filtration performance.
l High Throughput: Water production 2–3 times higher than traditional organic membranes.
l Strong Anti-Fouling: Hydrophilic and oil-repellent surface allows easy cleaning and stable performance.
l Circulating Cooling Water Treatment: Improves circulation efficiency and extends equipment life.
l Landfill Leachate Treatment: Provides deep filtration of suspended solids for subsequent concentration or reuse.
l Coal Chemical Wastewater: Concentration and purification of high-salt, high-organic-load wastewater.
l Coking Wastewater: Reduces COD and suspended solids, enabling resource recovery.
l Mine Water Treatment: Ensures stable treatment of high-salinity wastewater.
l Electroplating Wastewater: High-precision removal of suspended solids and heavy metals to meet discharge standards.
l Chemical Wastewater: Handles complex chemical compositions, protecting downstream equipment.
l Steel Industry Wastewater: Treats highly polluted, high-suspended-solids wastewater, improving system stability.
