Product Introduction: Powdered Activated Carbon (PAC) is a granular amorphous carbon material produced through carbonization, activation, crushing, grinding, and purification processes using premium raw materials such as wood chips, coconut shells, and coal. With its fine particle size, large specific surface area, and superior adsorption kinetics, it efficiently captures various pollutants in liquids and gases, making it indispensable in water treatment, food processing, and environmental remediation. Compared to granular activated carbon, powdered PAC offers advantages like faster adsorption rates, flexible dosing, and cost-effectiveness, making it widely applicable in emergency response and continuous industrial processes.

Appearance Characteristics: The powdered activated carbon appears as a fine black powder, free from obvious lumps or visible impurities, with a uniform color. The particle size distribution is precisely controllable, typically ranging from 80 to 325 mesh (equivalent particle size 18-150 μm). Among these, products with 100-200 mesh are most widely used in water treatment. For special scenarios, 50 mesh (300 μm) coarse powder or 400 mesh (38 μm) ultra-fine powder can be customized. When observed under a scanning electron microscope, its surface exhibits a well-developed pore structure, with irregular porous morphology providing ample sites for adsorption. The bulk density of the product is 0.35-0.55g/cm³, lighter than granular activated carbon, and it tends to produce a small amount of dust when poured. High-quality products have good dispersibility in water, with no obvious sedimentation or agglomeration, remaining uniformly suspended after standing. Depending on the raw material, coal-based powdered activated carbon tends to be grayish-black, while coconut shell and wood-based products are darker, appearing pure black, with wood-based products having a finer texture.

Core Features 1. Superior Adsorption Performance: As a core advantage, it boasts a BET specific surface area of 800-1600 m²/g, with 70%-85% micropores (<2nm) and 10%-25% mesopores (2-50nm). This pore structure exhibits exceptional capture capacity for small organic molecules, heavy metal ions, and pigment molecules. Key performance metrics include: iodine adsorption capacity of 800-1300 mg/g, methylene blue adsorption capacity of 100-220 mg/g, and caramel decolorization rate (for wood products) reaching 90%-98%. Under identical operating conditions, its adsorption rate outperforms granular activated carbon by 40%-60%, achieving adsorption equilibrium within 10-30 minutes.

Excellent physical dispersion: The fine and uniform particle size of the powder enables rapid dispersion in liquid systems, forming a stable suspension. The contact area with the target medium can reach 5-10 times that of granular activated carbon, effectively avoiding adsorption blind spots. With a narrow particle size distribution, over 90% of particles fall within the specified range, ensuring stable and consistent adsorption performance while minimizing substandard treatment due to particle size inconsistency.

Strong chemical stability: The product exhibits excellent chemical inertness, with a pH value stabilized between 5.5-11.0. Customized acidic (pH3.0-5.0) or alkaline (pH11.0-13.0) products can be produced according to application requirements. Coal-based products have a sulfur content of ≤0.3%, while wood and coconut shell products have a sulfur content of ≤0.1%, ensuring no chemical reactions with conventional components in the treatment medium. Food-grade products strictly comply with the GB/T 14909-2015 standard, with extremely low heavy metal content (arsenic ≤3mg/kg, lead ≤10mg/kg, mercury ≤0.1mg/kg), meeting food safety requirements.

Flexible process adaptability: This system requires no specialized fixed-bed equipment, enabling direct dosing into treatment systems via metering pumps or dry powder dosing devices. It is compatible with conventional equipment such as agitators, reaction tanks, and pipeline mixers, making it particularly suitable for emergency response to sudden pollution incidents. The dosage can be flexibly adjusted according to pollutant concentration, maintaining stable performance across concentrations from 10mg/L to 500mg/L, with controllable treatment costs.

Application Fields 1. Municipal and Industrial Water Treatment: In emergency water treatment scenarios at municipal water plants, the addition of 10-50mg/L effectively addresses issues like algal blooms, pesticide residues, and sudden odor surges. This solution rapidly eliminates earthy and moldy odors along with trace contaminants, reducing odor thresholds from 1000 odor threshold units to below 20, meeting the GB 5749-2022 Drinking Water Hygiene Standard. For industrial wastewater treatment, it is used for decolorization of dyeing effluents (achieving 85%-95% decolorization), COD reduction in chemical wastewater (removal rate 30%-60%), and heavy metal adsorption in electroplating wastewater (removal rates exceeding 90% for lead and cadmium), particularly suitable for pretreatment of refractory organic wastewater. In advanced treatment processes at wastewater plants, it reduces effluent COD and total nitrogen content, facilitating upgrades to higher standards.

Food and Beverage Industry: In the sugar industry, this process is used for decolorization and purification of sucrose and glucose. Adding 0.1%-0.3% of the solution effectively removes melanoidin and caramel pigments from sugar solutions, achieving a whiteness level above 95%. In alcohol production, it is applied to clarify baijiu (Chinese liquor), clarify beer, and decolorize fruit wines. It adsorbs aldehydes, fusel oils, and polyphenols in alcoholic beverages, enhancing purity and extending shelf life by 6-12 months. In the beverage sector, it is used to remove astringency and bitterness from fruit juices and tea drinks, eliminating tannic acid and other harsh substances while preserving the original flavor profile.

Pharmaceutical and Chemical Industries: In pharmaceutical applications, it serves as a pharmaceutical excipient for purifying drug intermediates such as antibiotics and vitamins, while adsorbing impurities including proteins, pigments, and residual solvents from raw materials, meeting the standards of the Pharmacopoeia of the People's Republic of China (2025 Edition). In chemical processing, it facilitates solvent recovery (e.g., acetone, ethanol, toluene) through adsorption-desorption cycles, achieving over 90% recovery rates. Additionally, in catalyst preparation, it functions as a support for noble metal catalysts to enhance catalytic efficiency.

Gas-phase purification and environmental remediation: In industrial exhaust treatment, this technology adsorbs VOCs (volatile organic compounds), sulfides, and nitrogen oxides, achieving 80%-90% efficiency in applications like printing and coating industries, often combined with catalytic combustion. For indoor air purification, it serves as the core material for air purifier filters and activated carbon packs, adsorbing pollutants such as formaldehyde, benzene, and TVOCs at 80-150mg/g, effectively improving indoor air quality. In waste incineration, it adsorbs highly toxic pollutants like dioxins, reducing exhaust hazards.

Agriculture and Aquaculture: In agriculture, this technology is applied to remediate soil heavy metal contamination by adsorbing heavy metal ions (e.g., lead, mercury, cadmium) from the soil, thereby reducing crop uptake. The treated soil can meet the GB 15618-2018 Soil Environmental Quality Standard. In aquaculture, a dosage of 5-10 mg/L effectively adsorbs ammonia nitrogen, nitrite, and residual feed residues in the water, improving the aquatic micro-ecosystem, reducing disease incidence in fish and shrimp, and enhancing survival rates.
