Activated Carbon Filter Cartridge 290x600

The activated carbon filter cartridge is a high-performance depth filtration element designed for the removal of chlorine, organic compounds, odors, and other contaminants from water and air streams. With substantial dimensions of 290mm in outer diameter and 600mm in length, this large-format cartridge is engineered for industrial and commercial applications requiring high flow rates and extended service life .

This activated carbon filter features a deep-bed construction filled with high-quality activated carbon granules that trap and hold contaminants through physical adsorption . Unlike standard pleated filters that only capture particles on the surface, the activated carbon media provides depth filtration, allowing contaminants to be adsorbed throughout the entire carbon bed .

Below is the parameter for the custom activated carbon air filter. If you need this type of filter, please send us your parameter information for confirmation.

• Dual-Function Filtration: The activated carbon cartridge provides both mechanical filtration and adsorption in a single element. It removes suspended particles while simultaneously adsorbing dissolved contaminants, chlorine, organic compounds, and odors . This combination simplifies system design and reduces the number of treatment stages required.
• High Adsorption Capacity: With iodine values of 800-1000 mg/g and specific surface area of 800-1000 m²/g, the activated carbon media offers exceptional adsorption capacity . This means more contaminants are removed before the carbon becomes saturated, extending service life.
• Effective Chlorine and VOC Removal: The carbon media demonstrates excellent removal efficiency for chlorine , chemical oxygen demand , and various organic compounds . It effectively eliminates unpleasant tastes and odors from water supplies.

• Deep-Bed Construction: Unlike thin-layer carbon filters, this filter features a deep granular carbon bed that provides extended contact time between the fluid and adsorption media. This ensures thorough contaminant removal even at higher flow rates.

• Mechanical Strength: With pressure rating of 0.4 MPa, the cartridge withstands typical operating pressures in water treatment and industrial applications . The internal and external support structures prevent media migration and maintain structural integrity.

The Activated Carbon Filter Cartridge serves critical roles across multiple industries:

• Industrial Water Treatment: Used in process water purification, dechlorination, organic contaminant removal, and pre-treatment for reverse osmosis systems.
• Municipal Water Conditioning: Applied in point-of-entry systems for communities, schools, and commercial buildings to improve taste, remove chlorine, and reduce organic contaminants from municipal water supplies .
• Pharmaceutical and Biotech: Used in purified water systems, water for injection (WFI) pre-treatment, and process water applications requiring removal of organic compounds and chlorine .
• Aquaculture and Fish Farming: Applied in recirculating aquaculture systems (RAS) to remove organic waste products, chlorine, and improve water quality for fish health .

• Air Purification Systems: Installed in industrial air scrubbers, HVAC systems, and fume hoods to remove gaseous pollutants, odors, and volatile organic compounds (VOCs) from exhaust or recirculated air .

• Wastewater Treatment: Applied in tertiary treatment stages to polish effluent by removing residual organic compounds and improving water quality before discharge or reuse .

For two decades, Huahang Filter has served numerous water treatment engineering companies and industrial clients, encountering a wide variety of water treatment needs. This experience has given us a deeper understanding of how to select the right activated carbon products and configuration solutions for our users.

Our carbon sources are high-quality coconut shell charcoal, coal-based charcoal, or wood-based charcoal, offering highly efficient adsorption. During the production process, we strictly control the particle size distribution and packing density of the carbon particles to ensure sufficient contact time while avoiding excessive pressure loss. The internal and external support structures are made of corrosion-resistant materials to prevent carbon particle migration and bypass.

Why Choose Huahang Filter

Look, activated carbon cartridges aren't complicated. It's carbon in a tube. But there's "carbon in a tube" and then there's doing it right. Here's the difference:

• The carbon itself matters. We don't just buy whatever's cheap. We source coconut shell carbon from reputable suppliers. We test it for iodine value, hardness, moisture content. If it doesn't meet spec, it doesn't go in a cartridge.
• Particle size matters. Too fine, and you get high pressure drop. Too coarse, and the water channels through without proper contact. We screen our carbon to keep the particle size consistent.
• Bed packing matters. If you just dump carbon in loose, it settles and leaves voids. Water finds the path of least resistance-those voids-and you get poor adsorption. We fill carefully to ensure uniform density.
• End caps matter. They need to be bonded properly so water doesn't bypass the carbon entirely. We use food-grade adhesives that hold up over time. For tougher applications, we weld stainless steel ends.
• Support layers matter. Inner and outer mesh keep the carbon contained and prevent media migration. You don't want carbon fines showing up downstream.

These aren't glamorous details. But they're the difference between a filter that works for a year and one that fails in three months.

Q: What contaminants does activated carbon remove?
A: Activated carbon effectively removes:

• Chlorine and chloramines (up to 96% removal)
• Organic compounds including pesticides, herbicides, and industrial chemicals
• Volatile organic compounds (VOCs) such as benzene, toluene, and chloroform
• Unpleasant tastes and odors from water or air
• Some heavy metals including mercury and iron (partial removal)
• Chlorinated solvents and disinfection byproducts

It does NOT remove dissolved minerals, salts, or hardness (calcium and magnesium).

Q: What is the difference between coconut shell, coal-based, and wood-based carbon?
A: Each type has distinct characteristics:

• Coconut shell carbon: Hard, dense, with high micropore volume. Excellent for adsorption of low-molecular-weight compounds and gases. Preferred for drinking water and food applications.
• Coal-based carbon: Good balance of micropores and mesopores. Economical choice for general industrial water treatment.
• Wood-based carbon: Higher mesopore and macropore volume. Better for decolorization and removal of larger organic molecules.

Q: What is the service life of the activated carbon filter cartridge?
A: Service life depends on feed water quality, flow rate, and contaminant loading. Typical applications achieve 6-12 months of service before carbon saturation . Indicators that replacement is needed include:

1. Detectable chlorine taste or odor in treated water
2. Increased total organic carbon (TOC) in effluent
3. Pressure drop increase (though less common than with particulate filters)

Q: Can the activated carbon cartridge be cleaned and reused?
A: Activated carbon cartridges are generally designed for single use and replacement. Once the carbon is saturated with adsorbed contaminants, it cannot be effectively cleaned in the field . In some industrial applications, spent carbon can be thermally reactivated (regenerated) off-site, but this is typically done in bulk quantities, not for individual cartridges. Simple rinsing with water does NOT restore adsorption capacity .
