Established in 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer in the filtration industry for over two decades. Our Needle-Punched Filter Cloth Bag for Wastewater Treatment Liquid Filtration is engineered to deliver consistent, high-efficiency solid-liquid separation in demanding industrial environments. With a precision 100 micron rating and a robust pressure tolerance of 1.0 MPa, this filter bag is designed to maximize filtration performance while minimizing downtime — a critical advantage for wastewater treatment plants and liquid processing facilities.
Our needle-punched nonwoven fabric structure provides a deep bed filtration mechanism, trapping particles throughout the media rather than only on the surface. This results in higher dirt-holding capacity and longer service life compared to conventional woven filter bags. The bag is available in various materials (polyester, polypropylene, or custom blends) to suit specific chemical compatibility and temperature requirements. Whether you are treating industrial effluent, municipal sewage, or process water, this filter bag offers reliable performance under continuous operation.
Key Features & Technical Specifications
- Needle-Punched Construction: Creates a three-dimensional porous structure for efficient particle capture and high flow rates.
- 100 Micron Filtration Rating: Effectively removes suspended solids down to 100 microns, ideal for primary and secondary wastewater treatment stages.
- 1.0 MPa Pressure Rating: Withstands high operating pressures without bursting, ensuring safe and continuous filtration.
- Chemical Resistance: Available in polypropylene (PP) for acidic/alkaline environments or polyester (PET) for general aqueous applications.
- Customizable Size & Connection: Bags can be produced in any length, diameter, and with ring, strap, or snap ring closures to fit existing housings.
- High Dirt-Holding Capacity: Deep filtration mechanism traps more contaminants per bag, reducing replacement frequency.
- Low Pressure Drop: Optimized fiber density minimizes energy consumption while maintaining filtration efficiency.

Frequently Asked Questions
-
Q: What is the difference between needle-punched and woven filter bags?
A: Needle-punched bags use a nonwoven fabric created by mechanically entangling fibers, resulting in a thicker, more porous media with deep filtration. Woven bags have a mesh-like structure that filters only on the surface. Needle-punched bags offer higher dirt-holding capacity and better particle retention for wastewater applications. -
Q: Can this filter bag be used for oily wastewater?
A: Yes, but material selection is important. Polypropylene (PP) is preferred for oil-water separation due to its oleophilic/hydrophobic properties. We can customize the fabric blend to optimize oil removal. Please consult our technical team for specific recommendations. -
Q: What is the maximum flow rate for a 100 micron needle-punched bag?
A: Flow rate depends on bag size, housing design, and fluid viscosity. As a guideline, a standard size 2 (180x810mm) bag can handle approximately 10–20 m³/h for water-like fluids. Contact us with your parameters for a precise calculation. -
Q: How do I determine the correct connection type?
A: Common options include plastic ring (for standard housings), metal ring (for high-temperature), and strap (for quick change). We recommend matching the bag's connection to your existing filter housing. If unsure, send us a photo or drawing of your current bag/housing, and we will advise. -
Q: Are these bags reusable?
A: Needle-punched filter bags are typically single-use, but they can be washed and reused if the media is not damaged and the filtrate is not hazardous. For high-solid loads, we recommend replacing the bag to maintain efficiency. Reusable frames are available separately. -
Q: What is the typical lead time?
A: For standard sizes, lead time is 7–15 days after order confirmation. Custom orders may require 15–25 days depending on complexity. We also maintain stock for popular sizes. Please contact our sales team for current availability. -
Q: Can you provide samples for testing?
A: Yes, we offer free samples (up to 5 pieces) for qualified inquiries. You only pay for shipping. We can produce samples in your desired material and micron rating to test in your actual process. -
Q: Do you export to my country?
A: We export worldwide. Our main markets include North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. We have experience with international shipping documentation and can arrange door-to-door delivery if needed.
