Introduction
Water is very important in people's daily life, and the quality of water resources directly affects people's living standards. This article takes the basic principles and characteristics of ultrafiltration membrane technology as the starting point, analyzes the application of ultrafiltration membrane technology in water treatment, and introduces our ultrafiltration membrane.
The Critical Role of Ultrafiltration in Modern Water Treatment
Ultrafiltration membranes operate at a 0.01–0.1 micron pore size, effectively removing:
1. Suspended solids, bacteria, and viruses
2. Heavy metals (e.g., lead, mercury, arsenic)
3. Organic pollutants (e.g., dyes, pharmaceuticals, microplastics)
4. Colloidal particles and turbidity
Unlike conventional filtration methods, UF membranes provide consistent performance with minimal chemical usage, making them a sustainable choice for large-scale water reuse projects.
Why Our UF Membranes Stand Out:
✔ Factory-Direct Pricing – Eliminating intermediaries allows us to offer premium UF membranes at highly competitive rates.
✔ Rapid Production & Delivery – Our streamlined manufacturing ensures short lead times, even for bulk orders.
✔ Customizable Configurations – Available in hollow fiber, flat-sheet, and spiral-wound designs to fit diverse treatment needs.
✔ Low Fouling & Long Lifespan – Engineered for high flux stability, reducing maintenance costs.
Key Applications in Wastewater Reuse
1. Advanced Municipal Wastewater Recycling
Municipalities worldwide face increasing pressure to treat and reuse sewage effluent for irrigation, industrial cooling, and even potable water augmentation. Our UF membranes serve as a high-efficiency tertiary treatment, removing pathogens, organic matter, and micropollutants to meet WHO and EU reuse standards.
Case Study: A Spanish wastewater plant integrated UF membranes into a gravity-driven system, achieving >87% turbidity removal and complete elimination of E. coli, making the water safe for agricultural reuse.
2. Industrial Wastewater Treatment & Zero-Liquid Discharge (ZLD)
Industries such as textiles, pharmaceuticals, and electroplating generate highly contaminated wastewater. Our UF membranes act as a pre-treatment for RO systems, significantly reducing COD, heavy metals, and dye residues:
Textile Wastewater: UF-RO combined systems achieve >99% COD rejection, enabling water recycling in dyeing processes.
Pharmaceutical Effluents: UF membranes remove antibiotics and drug residues with >75% efficiency, preventing environmental contamination
3. Emerging Pollutant Removal
Conventional treatment struggles with pharmaceuticals, pesticides, and endocrine disruptors. Our UF membranes, when combined with activated carbon or advanced oxidation, enhance removal rates:
Amoxicillin Reduction: Up to 69% removal when UF is paired with powdered activated carbon (PAC).
Phenolic Compounds: Novel enzyme-enhanced UF systems selectively remove >99.5% of hydrophobic phenols while avoiding membrane fouling
Technological Innovations & Sustainability Benefits
✔ Energy-Efficient Operation
Our UF membranes operate at low pressure (0.1–0.5 bar), reducing energy consumption by 60% compared to traditional RO systems8.
✔ Recycled Membrane Solutions
We support circular economy initiatives by repurposing end-of-life RO membranes into UF-like filters, extending their usability in tertiary wastewater treatment3.
✔ Smart Fouling Control
Advanced backwashing and chemical cleaning protocols ensure long-term flux stability, minimizing downtime and operational costs.

Q&A
Q: Can UF membranes tolerate chlorine exposure?
A: PVDF/PES: Tolerate low-dose chlorine (<200 ppm); CA: Degrades. Chlorine cleans biofilms but shortens membrane lifespan with prolonged use.
Q: How to calculate UF system recovery rate?
A: *Recovery (%) = (Permeate flow / Feed flow) × 100*. Typical UF recovery: 70–90% (depends on feed quality and fouling control).
Q: What is "concentration polarization" in UF?
A: Accumulation of rejected solutes near the membrane surface, reducing flux. Mitigated by cross-flow velocity, pulsation, or backwashing.
