Ultra-High Dirt Capacity Filter Cartridge - 3X Longer Life for Wastewater & Leachate Prefiltration


The Ultra-High Dirt Capacity Filter Cartridge incorporates a nanofiber polypropylene membrane and a multi-layer graded structure to deliver 1.5x higher flow rate and over 3x longer service life than conventional filters. Designed for challenging liquids such as landfill leachate, industrial wastewater, and water reclamation, it significantly reduces replacement frequency and operational costs while maintaining stable filtration performance under high-contamination conditions.

APPLICATIONS

Industrial Wastewater Reclamation & Reuse: Ideal for pre-filtration and clarification in municipal and industrial water recycling systems, effectively handling variable and high-particulate loads.

Landfill Leachate Treatment: Provides robust pre-filtration for complex and aggressive leachate streams prior to downstream treatment processes like reverse osmosis or biological treatment.

High-COD Industrial Effluent: Suitable for pretreatment of wastewater with high Chemical Oxygen Demand (COD) from industries such as chemicals, pharmaceuticals, food & beverage, and textiles.

Complex Process Water Filtration: Used for filtering process water containing diverse and challenging contaminants where high dirt holding capacity is critical to reduce downtime.


Compliance: D-HFA

How does the Ultra-High Dirt Capacity Filter Cartridge achieve 3X longer service life compared to standard filters?

The Ultra-High Dirt Capacity Filter Cartridge achieves extended service life through its proprietary nanofiber polypropylene (PP) media and a multi-layer graded density structure. Unlike standard filters that clog quickly on the surface, this design allows for deep-bed filtration, capturing up to 3 times more contaminants. This makes it ideal for reducing change-out frequency in high-load applications like industrial wastewater and water reclamation.


Is this filter cartridge suitable for filtering high-COD wastewater or landfill leachate?

Yes, the D-HFA series is specifically engineered for challenging fluids such as landfill leachate and high-COD industrial effluent. Its robust pleated construction resists premature blocking caused by complex particulates and gelatinous contaminants often found in these streams. It serves as an excellent pre-filtration stage to protect downstream Reverse Osmosis (RO) systems from fouling.


Can I use this cartridge to replace existing 3M or Pall high flow filters?

Yes, our Ultra-High Dirt Capacity Filter Cartridges are designed as direct replacements for major brands like 3M (CUNO), Pall, and Parker high flow series. They feature compatible end caps and dimensions (20", 40", 60") to fit seamlessly into your existing filter housings without any equipment modification, offering a cost-effective alternative with equal or superior performance.


What is the advantage of using nanofiber technology in high flow filter cartridges?

Nanofiber technology creates a significantly tighter and more uniform pore structure compared to traditional melt-blown fibers. This allows the cartridge to maintain a high flow rate (1.5x standard) while capturing finer particles. The increased surface area of the nanofibers enhances the dirt holding capacity, ensuring consistent filtration efficiency even under variable pressure conditions


How does switching to this ultra-high capacity filter reduce overall operational costs?

Switching reduces costs in three ways:

  1. Lower Material Costs: Longer life means buying fewer cartridges per year.

  2. Reduced Downtime: Fewer change-outs mean less interruption to production processes.


  3. Labor Savings: Less maintenance time is required for filter replacement and disposal. For high-contamination industries, this can result in a total cost of ownership (TCO) reduction of over 30%.


Can your filters handle high-temperature or corrosive environments?

Yes, we offer filter cartridges made from PTFE, PES, stainless steel, and other materials resistant to high temperatures, acids, alkalis, and aggressive chemicals.


What is the difference between surface filtration and depth filtration?

In surface filtration, a filter with a uniform pore design, traps contaminants that are larger than the pore size of the media. In depth filtration, the contaminants are trapped at multiple levels within the filter because of the tapered pore structure of the depth filters.
