Product Overview
FHM is our wood-based powdered activated carbon produced through physical (steam) activation—a process that preserves the natural pore structure of the wood while developing extensive adsorption capacity. Unlike chemically activated wood carbons, FHM carries no residual phosphoric acid or zinc chloride, making it the preferred choice for applications where chemical purity is paramount.
The wood base—typically hardwood chips selected for their high cellulose and low ash content—delivers a pore structure rich in mesopores. This makes FHM particularly effective for color body removal, as the larger pore dimensions accommodate the molecular size of natural pigments and synthetic dyes.

Key application areas
- Sugar refining — decolorization of cane and beet sugar syrups
- Edible oil purification — bleaching and deodorization of vegetable oils
- Beverage production — wine, beer, and spirits clarification
- Pharmaceutical processing — active ingredient purification
- Wastewater decolorization — textile and dyeing effluent treatment
Food-Grade Advantages
- No Chemical Residuals: Physical activation means no acid or salt residues that could affect taste or safety
- Low Heavy Metals: Wood base naturally contains fewer metal contaminants than coal or coconut shell
- High Methylene Blue: >250 mg/g indicates extensive mesopore volume for color body adsorption
- Rapid Filtration: The particle size distribution is optimized for fast settling and easy separation
