Established in 1998, Anping County Boli Hardware Wiremesh Products Factory is a specialized manufacturer with over two decades of expertise in producing precision filtration solutions. Our wedge wire filter, featuring a precise 0.25mm slot opening and constructed from premium 304 stainless steel, is engineered to deliver reliable performance in demanding water treatment applications. Designed for long service life, this filter offers exceptional resistance to corrosion, clogging, and mechanical wear, making it a cost-effective choice for municipal and industrial water treatment plants worldwide.
This wedge wire filter is manufactured using advanced continuous slot technology, which creates a V-shaped profile that minimizes particle entrapment and ensures consistent filtration efficiency. The 0.25mm slot width is ideal for fine particle removal while maintaining high flow rates, reducing pressure drop, and minimizing cleaning frequency. Whether used in intake screens, filter underdrains, or sewage treatment systems, our product provides reliable solids-liquid separation.

Detailed Product Advantages
Superior Filtration Performance: The 0.25mm slot opening is precisely controlled during manufacturing, ensuring consistent particle retention down to 250 microns. This level of accuracy is critical for removing fine sediments, algae, and suspended solids in water treatment processes.
Enhanced Durability: 304 stainless steel provides excellent resistance to rust, chlorine, and biological fouling commonly found in water treatment plants. The wedge wire structure is welded at every intersection, creating a monolithic unit that can withstand high-pressure backwashing and mechanical stress without deformation.
High Flow Capacity: Unlike perforated plate or mesh filters, the wedge wire design offers a large open area (up to 60% depending on slot/wire ratio). This allows higher flow rates with lower pressure drop, reducing energy consumption in pumping systems.
Self-Cleaning Action: The V-shaped profile of the slot encourages particles to slide off or be dislodged during backwashing, reducing the need for manual cleaning. This feature is especially valuable for continuous operation in automated water treatment plants.
Customization Options: As a manufacturer, we offer flexibility in dimensions, end connections, and support structures. Our engineering team can design custom filters to fit your existing equipment, whether for new installations or retrofits.

Frequently Asked Questions (FAQ)
-
What is the typical lifespan of a 0.25mm slot wedge wire filter in water treatment?
With proper maintenance, the filter can last 5–10 years or more, depending on water chemistry and operating conditions. The 304 stainless steel construction ensures excellent corrosion resistance. -
Can this filter be used for both intake screening and inside filtration vessels?
Yes. The wedge wire filter is versatile and can be used as a raw water intake screen, filter underdrain, or in pressure vessel applications. Custom end connections allow integration into various systems. -
Is the 0.25mm slot suitable for removing fine sand and silt?
Absolutely. The 0.25mm slot (250 microns) effectively retains fine sand, silt, and algae. For finer filtration, we offer slots down to 0.1mm (100 microns) upon request. -
How do I clean the filter if it becomes clogged?
Backwashing with water or air is typical. The V-shaped slot design helps release trapped particles. For severe fouling, chemical cleaning (acid or caustic) can be used without damaging the stainless steel. -
Do you offer custom lengths or diameters for my existing system?
Yes. We can customize the filter length, outer diameter, wire diameter, and end connections to match your specific requirements. Please provide your dimensions or drawings for a quotation. -
What is the minimum order quantity (MOQ) for this product?
Our MOQ is flexible. For standard sizes, small quantities (e.g., 10 pieces) are acceptable. For custom designs, a minimum quantity may apply depending on complexity. -
How do you ensure the slot width accuracy during production?
We use precision winding machines and laser measurement tools to control the slot opening within ±0.02mm tolerance. Each filter is inspected before shipment. -
Can you provide samples for testing before bulk order?
Yes, sample orders are welcome. We can produce a sample filter based on your specifications. Sample cost is negotiable, and we can deduct the cost from your first bulk order.
