Why Choose ZLN Cross-Flow Membrane Filtration Unit?
- Proven Cross-Flow Technology: Unlike dead-end filtration, the cross-flow mode continuously sweeps the membrane surface, reducing cake buildup and maintaining high flux over long operation cycles.
- IP65 Protection for Demanding Sites: Ideal for food processing plants, chemical facilities, and outdoor installations where water, dust, or wash-down is a concern.
- Customizable Flow Rate: The 1–10 m³/h range can be fine-tuned via variable frequency drive (VFD) or by adjusting the number of membrane modules – perfect for both batch and continuous processes.
- Superior Membrane Selection: We offer a variety of membrane polymers and pore sizes to match your feed water characteristics, from low-fouling UF to high-rejection RO.
- Energy-Efficient Operation: Low-pressure pumps and optimized piping reduce energy consumption by up to 20% compared to conventional systems, lowering your total cost of ownership.
- Global Support & Fast Delivery: Shipped from our factory in Tianjin, China, we provide worldwide logistics and responsive after-sales service.
Our cross-flow membrane filtration unit is not just a piece of equipment – it's a comprehensive solution that helps you improve product quality, reduce waste, and meet environmental regulations.

Frequently Asked Questions (FAQ)
-
Q: What types of membranes does this unit support?
A: The unit is compatible with ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) membranes. The specific membrane type can be selected based on your feed water quality and target separation. We can also customize the membrane housing size. -
Q: Can the capacity be adjusted after installation?
A: Yes, the flow rate is adjustable via a variable frequency drive (VFD) or by changing the number of membrane modules. The standard range is 1–10 m³/h, but we can design larger or smaller capacities upon request. -
Q: Is the IP65 rating sufficient for outdoor use?
A: Absolutely. The IP65 enclosure protects against dust ingress and low-pressure water jets from any direction, making it suitable for outdoor installations, wash-down areas, and humid environments. -
Q: What is the typical maintenance schedule?
A: Maintenance intervals depend on feed water quality. Generally, we recommend a chemical cleaning every 2–4 weeks. The system includes a CIP (clean-in-place) function for easy cleaning. Routine checks on pumps, seals, and sensors are advised. -
Q: Can I use this unit for wastewater with high suspended solids?
A: Yes, but pre-treatment like a screen or sedimentation may be needed to protect the membrane. Our cross-flow design handles moderate solids, but we can recommend a pre-filtration package if necessary. -
Q: What is the warranty period?
A: Standard warranty is 12 months from the date of shipment. Extended warranty options are available upon request. We also provide spare parts and technical support throughout the product life. -
Q: Do you provide installation and commissioning support?
A: Yes, we offer on-site supervision and remote guidance. Our engineers can travel to your site for commissioning, or we can provide detailed manuals and video tutorials.
