Introduction
Industrial wastewater poses significant environmental challenges, particularly in sectors such as textiles, pharmaceuticals, paper manufacturing, and chemical processing. Effective treatment and water reuse are critical for regulatory compliance and sustainable operations. Ultrafiltration (UF) membranes have become a cornerstone technology in industrial wastewater management, offering high-efficiency filtration, reduced chemical usage, and energy savings compared to conventional methods.
As a leading Chinese manufacturer of ultrafiltration membranes, we specialize in high-performance, cost-effective solutions tailored for industrial applications. Our in-house production capabilities ensure competitive pricing, rapid delivery, and consistent quality, making us a trusted partner for global wastewater treatment projects.
Why Ultrafiltration Membranes Are Ideal for Industrial Wastewater?
Ultrafiltration is a pressure-driven separation process that removes suspended solids, colloids, bacteria, and macromolecules (0.01–0.1 µm) while allowing water and small solutes to pass through. Key advantages include:
✅ Superior Contaminant Removal – Effective against turbidity, organic pollutants, and pathogens
✅ Lower Operational Costs – Minimizes chemical consumption and sludge production
✅ Compact System Design – Requires less space than traditional sedimentation or biological treatment
✅ Water Reuse Potential – Produces high-quality effluent suitable for recycling or further polishing (e.g., reverse osmosis)
✅ Energy Efficiency – Operates at lower pressures compared to nanofiltration (NF) or reverse osmosis (RO)
Key Industrial Applications of UF Membranes
1. Textile & Dyeing Wastewater Treatment
Textile effluents contain complex dyes, surfactants, and heavy metals, which are challenging to treat. UF membranes achieve >90% removal of color and organic load, significantly reducing chemical oxygen demand (COD) and meeting discharge standards.
Performance Highlights:
✔ PVDF membranes demonstrate 97–99% turbidity removal and stable flux (>18 L/m²·h), outperforming PP membranes.
✔ Combined with RO, UF enables near-zero liquid discharge (ZLD) by recovering reusable water.
2. Pharmaceutical Wastewater Purification
Pharmaceutical wastewater contains active drug residues, solvents, and toxic organics. UF membranes effectively retain high-molecular-weight compounds, preventing environmental contamination.
Case Study:
✔ Hybrid UF + Advanced Oxidation (AOP) systems achieve >90% COD removal and 100% pathogen elimination, ensuring compliance with stringent regulations
3. Paper & Pulp Effluent Treatment
Pulp and paper mills generate high-COD black liquor and whitewater. While standalone UF reduces COD to ~600 mg/L, pre-treatment with coagulation enhances performance, achieving <50 mg/L COD (meeting GB3544-2008 standards).
Optimized Approach:
✔ 2000-Da MWCO membranes coupled with coagulation yield 61 mg/L COD in black liquor and 49 mg/L in whitewater.
4. Coke Plant Wastewater Reuse
Coking wastewater contains phenols, cyanides, and ammonia. PVDF-based UF systems provide high mechanical strength and fouling resistance, enabling direct reuse or RO feedwater production.
Innovation Spotlight:
✔ Submerged UF modules reduce footprint and automate operations, ideal for space-constrained plants
