As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory brings decades of expertise in filtration solutions. Our Skeleton-Supported Filter Cartridge for Wastewater Treatment with 100μm coarse filtration is engineered to deliver reliable, high-performance solid-liquid separation for industrial applications. The robust skeleton support ensures the filter media maintains its shape under high flow rates and pressure surges, making it ideal for challenging wastewater environments. With an annual export value of US$5-10 million and shipments to over 15 markets worldwide, we are proud to offer this durable, cost-effective cartridge that minimizes downtime and extends service life.
Key Features & Technical Specifications
- Precision Filtration at 100 Microns: Effectively removes suspended solids, sand, silt, and large particles from wastewater, protecting downstream equipment like pumps, membranes, and heat exchangers.
- Rigid Skeleton Support: Inner core made of stainless steel or high-strength plastic prevents collapse under differential pressure, ensuring consistent filtration performance even in fluctuating flow conditions.
- High Flow Capacity: Large surface area and optimized pleat design reduce pressure drop, allowing higher flow rates per cartridge compared to standard melt-blown or string-wound filters.
- Chemical Compatibility: Available in polypropylene, polyester, or nylon media; resistant to acids, alkalis, and organic solvents commonly found in industrial wastewater.
- Easy Installation & Replacement: Standard 2.5-inch, 4.5-inch, or 6-inch diameters with 10-40 inch lengths, compatible with most filter housings. End cap options include open end, closed end, or double open end (DOE).
- Cost-Effective Operation: Longer service life reduces replacement frequency, lowering overall operating costs. The skeleton support allows for backwashing in some applications, extending cartridge life further.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a skeleton-supported filter cartridge and a standard melt-blown cartridge?
A: A skeleton-supported cartridge has a rigid inner core (usually stainless steel or plastic) that prevents the filter media from collapsing under high pressure or flow surges. This makes it more durable and suitable for wastewater applications with variable flow, whereas standard melt-blown cartridges are more prone to deformation.
Q2: Can this cartridge be backwashed or cleaned?
A: In some applications, the skeleton-supported design allows for backwashing to remove accumulated solids, extending the cartridge life. However, for optimal performance, we recommend replacing the cartridge when pressure drop exceeds the maximum limit. Please consult our technical team for backwashing feasibility based on your specific media and contaminants.
Q3: What filter media options are available for the 100 micron rating?
A: We offer polypropylene, polyester, and nylon mesh media. Polypropylene is common for general wastewater, polyester for higher temperature resistance, and nylon for better chemical compatibility with solvents. Custom media can be sourced upon request.
Q4: What is the typical lifespan of this cartridge in a wastewater treatment system?
A: Lifespan depends on the influent solids concentration, flow rate, and operating conditions. In municipal wastewater pre-filtration, a cartridge can last 2-6 months. In heavy industrial wastewater, it may be 1-3 months. We recommend monitoring pressure drop and replacing when it increases by 2-3 times the initial clean pressure drop.
Q5: Do you offer custom sizes or end cap configurations?
A: Yes, we can customize outer diameter, length, and end cap type (open, closed, DOE, or with gaskets) to fit your existing housing. Please provide your housing dimensions and requirements for a quotation.
Q6: Is this cartridge suitable for drinking water or food contact applications?
A: This cartridge is designed for industrial wastewater treatment and coarse filtration. For potable water, food-grade materials and certifications may be required. We can discuss food-grade options if needed, but standard product is not intended for drinking water without further validation.
Q7: What is the minimum order quantity (MOQ)?
A: MOQ for standard sizes is typically 50 pieces per size. For custom sizes, MOQ may be higher. Please contact our sales team for specific MOQ details.
Q8: How do you ensure the quality of the filter cartridges?
A: We have a rigorous quality control process including material inspection, dimensional checks, and pressure testing on sample batches. Our factory has been producing filtration products since 1998, and we maintain consistent quality through standardized production procedures.
