Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, proudly presents our Needle-Punched Filter Bag for Wastewater Treatment. Engineered with high-quality polypropylene fibers and precision needle-punched technology, this 50-micron filter bag delivers reliable solid-liquid separation in demanding industrial environments. With a robust thermal tolerance up to 120°C, it effectively removes suspended solids, sludge, and contaminants from wastewater streams, extending equipment life and reducing downtime. Our factory’s two decades of experience and US$5–10 million annual export value ensure consistent quality and global compliance.

Key Features & Technical Specifications

Material: 100% virgin polypropylene (PP) – excellent chemical resistance to acids, alkalis, and organic solvents.
Filtration Precision: 50 micron nominal rating – captures particles ≥50 µm effectively, suitable for primary and secondary wastewater treatment.
Thermal Stability: Continuous operating temperature up to 120°C (248°F) – ideal for hot process streams.
Fabric Structure: Needle-punched nonwoven – high porosity, deep filtration, and high dirt-holding capacity.
Seam Strength: Ultrasonic or heat-sealed seams – leak-proof and durable under pressure.
Ring Options: Available with stainless steel snap ring, plastic ring, or flange – compatible with standard bag filter housings.
Customization: Sizes, rings, and micron ratings can be tailored per customer requirements.

Performance Data (Typical)

Parameter	Value
Filtration area	0.25 – 1.0 m² (standard sizes)
Maximum pressure drop	2.0 bar (29 psi) at 20°C
Flow rate (per bag)	10 – 50 m³/h (depending on viscosity and particle load)
Initial efficiency	≥ 90% for particles ≥ 50 µm

Benefits for Your Operation

Cost-effective: High dirt-holding capacity reduces bag change frequency, lowering total cost of ownership.
Easy installation: Standard ring design fits most bag filter housings without modification.
Chemical compatibility: Polypropylene withstands a wide pH range (1–14), making it versatile for various wastewater chemistries.
Thermal resilience: Handles hot liquids up to 120°C, suitable for industrial processes like cooling water, boiler feed, and chemical processing.
Environmental compliance: Helps meet discharge standards by effectively removing suspended solids.
Customizable: Available in different lengths, diameters, and ring types to match your existing filtration system.

Frequently Asked Questions

What is the maximum operating temperature of this filter bag?
The bag is designed for continuous use up to 120°C (248°F). Higher temperatures may be possible for short periods; please consult our technical team for specific conditions.
Can this bag be used for filtering chemicals other than wastewater?
Yes, polypropylene is resistant to many acids, alkalis, and solvents. It is suitable for chemical processing, food & beverage, pharmaceutical, and general industrial filtration.
What ring options are available?
We offer stainless steel snap rings, plastic rings (polypropylene), and flanged rings. Standard sizes fit most bag filter housings. Custom rings are also available upon request.
Is the bag washable and reusable?
This needle-punched filter bag is primarily designed for single-use disposal. However, depending on the application and contaminant, some bags can be cleaned (e.g., backwashing) for limited reuse. We recommend testing in your specific process.
Do you provide custom sizes?
Absolutely. We can manufacture bags in various lengths (up to 2000 mm) and diameters (up to 500 mm) to fit your housing. Minimum order quantity may apply.
What is the typical lead time?
Standard sizes are usually shipped within 7–15 working days. Custom orders may take 15–25 working days, depending on complexity and quantity.
How do I know which micron rating to choose?
The 50 micron rating is ideal for removing visible suspended solids. For finer filtration (e.g., 1–25 microns), we offer other grades. Contact our technical team to recommend the best micron size based on your particle analysis.
Do you have certifications for quality management?
We follow strict internal quality control procedures. Specific certifications (e.g., ISO) are available upon request; please inquire with our sales team for details.
