Ultrafiltration Membrane For Water Treatment

Product Overview

T he Ultrafiltration (UF) Membrane is an advanced sep aration technology widely used in water purification and wastewater treatment. It employs a semi-permeable membrane with precise pore sizes (typically 0.01–0.1 µm) to remove suspended solids, colloids, bacteria, and macromolecules while allowing water and dissolved salts to pass through.
This process ensures high-quality filtrate suitable for various industrial, municipal, and domestic water treatment applications.

Working Principle

Ultrafiltration operates under low transmembrane pressure to drive water through the membrane surface.
Contaminants larger than the membrane pores are retained on the surface (retentate), while clean water (permeate) passes through.
Depending on the system design, UF membranes can be configured for outside-in or inside-out filtration modes.
Periodic backwashing and chemical cleaning maintain long-term performance and extend membrane life.

Features

• High Filtration Accuracy – Effectively removes suspended solids, colloids, bacteria, and particles larger than 0.01 μm.
• Stable and Consistent Permeate Quality – Delivers high flux and clear, particle-free water.
• Excellent Chemical Resistance – Compatible with various cleaning agents such as NaOCl, acids, and alkalis.
• Superior Mechanical Strength – PVDF and PES materials provide high durability, oxidation resistance, and fouling resistance.
• Energy-Efficient Operation – Works under low transmembrane pressure, reducing overall energy consumption.
• Easy Cleaning and Maintenance – Equipped with automatic backwashing and chemical cleaning functions for extended membrane life.
• Long Service Life – Optimized membrane structure ensures reliable performance and long-term stability.
• Flexible Configuration – Available in different materials, pore sizes, and module types to meet various application requirements.
