Hollow fiber membranes are a type of ultrafiltration (UF) membrane in which thousands of fine fibers form a compact module. Water or process liquid passes through the porous fiber walls, allowing clean permeate to flow inside while retaining suspended solids, bacteria, viruses, and other impurities outside. This makes hollow fiber technology highly efficient for both domestic and industrial water treatment applications.

• Typical pore size: 0.01–0.1 μm, ensuring removal of bacteria, viruses, and turbidity.
• Operates under low transmembrane pressure, saving energy compared to other filtration methods.
• Provides high surface area per module, resulting in compact system designs.
• Can be operated with outside-in or inside-out flow depending on application.

With their compact design, high reliability, and long service life, hollow fiber membranes have become one of the most widely used ultrafiltration solutions worldwide. They are suitable for both small-scale domestic systems and large industrial plants, offering consistent water quality with minimal maintenance.
