In an era where environmental sustainability and public health are paramount, powdered activated carbon (PAC) has emerged as a versatile solution for purification challenges across industries. With its exceptional adsorption capacity and adaptability, PAC plays a critical role in addressing contamination, odor control, and process optimization.
Powdered activated carbon is a microporous material derived from organic sources like coal, wood, or coconut shells through controlled thermal activation. Its labyrinthine pore structure, with surface areas exceeding 1,000 m²/g—enables unparalleled adsorption of contaminants at molecular levels. Unlike granular activated carbon (GAC), PAC’s fine particle size (typically <0.18 mm) ensures rapid reactivity, making it ideal for short-contact-time applications.
1. Drinking Water Treatment
PAC is widely used to remove organic compounds, pesticides (e.g., atrazine), and disinfection byproducts like trihalomethanes (THMs). Municipal plants often dose PAC during coagulation stages to address seasonal taste/odor issues caused by algae blooms. For example, 5–50 mg/L PAC can reduce geosmin concentrations by 80–95% within 30 minutes.
2. Wastewater Remediation
Industrial wastewater containing dyes, phenolic compounds, or heavy metals (e.g., mercury, chromium) benefits from PAC’s adsorption capabilities. Textile factories employ PAC dosages of 0.5–2.5 g/L to decolorize effluents, achieving >90% dye removal efficiency.
3. Food & Beverage Processing
PAC (200–800 ppm) effectively removes pigments and oxidation products in edible oil refining. Beverage manufacturers use PAC to eliminate off-flavors in juices and alcoholic drinks—a 0.1% PAC dose can reduce polyphenol content by 70% in wine stabilization.
4. Pharmaceutical Purification
PAC adsorbs endotoxins, pyrogens, and impurities during antibiotic and vaccine production. Typical applications include batch treatment with 0.1–0.5% PAC (w/v) followed by precision filtration.
5. Air Pollution Control
PAC is a carrier for catalytic chemicals in flue gas treatment, particularly for mercury removal in coal-fired power plants. Injection rates of 1–5 lb/MMacf (million actual cubic feet) can achieve 60–90% Hg capture.
6. Emergency Spill Response
Due to its rapid deployment capability, PAC is critical for adsorbing toxic spills (e.g., pesticide leaks) in waterways. Response teams often use 100–500 mesh PAC for optimal dispersion and sedimentation.
Selecting the right PAC requires understanding key parameters:
| Parametro | Typical Range | Application Considerations |
| Dimensione delle particelle | 90% <75 µm (200 mesh) | Finer particles enhance kinetics but complicate filtration |
| Numero di iodio | 800–1,200 mg/g | Higher values indicate superior VOC adsorption |
| Superficie | 900–1,500 m²/g | Critical for large-molecule contaminants |

Powdered activated carbon (PAC) treatment is a widely recognized adsorption technology employed across industries to remove organic and inorganic contaminants from liquids and gases. With its high surface area, porous structure, and exceptional adsorption capacity, PAC has become a cornerstone in environmental remediation, water purification, and industrial processes.
Activated carbon is derived from carbon-rich materials such as wood, coal, or coconut shells through pyrolysis and activation processes. The resulting product possesses a vast network of micropores (1–2 nm) and mesopores (2–50 nm), providing a surface area of 500–1,500 m²/g. PAC, characterized by its fine particle size (10–50 μm), offers rapid adsorption kinetics due to shorter diffusion pathways compared to granular activated carbon (GAC).
The adsorption mechanism involves two primary interactions:
Physical adsorption: Driven by van der Waals forces, this process traps contaminants within the carbon's porous matrix.
Chemical adsorption: Functional groups on PAC surfaces (e.g., hydroxyl, carboxyl) form covalent or ionic bonds with specific pollutants, such as heavy metals or charged organic compounds.
Factors influencing PAC efficiency include particle size, pH, temperature, and contact time. For instance, smaller PAC particles enhance adsorption rates but complicate post-treatment separation.
2.1 Water and Wastewater Treatment
PAC is extensively used in municipal and industrial water treatment to remove organic matter, pesticides, pharmaceuticals, and taste/odor-causing compounds. For example, in drinking water plants, PAC effectively adsorbs geosmin and 2-methylisoborneol (MIB), which are resistant to conventional coagulation methods.
2.2 Industrial Effluent Remediation
Industries such as textiles, petrochemicals, and food processing utilize PAC to treat wastewater containing dyes, phenols, and volatile organic compounds (VOCs). A study by Li et al. (2022) demonstrated 95% removal of azo dyes from textile effluents using PAC-modified filtration systems.
2.3 Air Pollution Control
PAC injection systems capture gaseous pollutants, including hydrogen sulfide (H₂S) and mercury vapor, in flue gases. Its application in incinerators and chemical plants aligns with tightening global emission regulations.
2.4 Medical and Pharmaceutical Uses
In emergency medicine, PAC serves as an antidote for acute poisoning by adsorbing toxins in the gastrointestinal tract. It is also employed in pharmaceutical manufacturing to decolorize solutions and remove endotoxins.
3.1 Strengths
High efficiency: PAC achieves rapid contaminant removal even at low concentrations.
Flexibility: It can be injected directly into existing treatment systems without infrastructure modifications.
Cost-effectiveness: Lower operational costs compared to GAC in batch processes.
3.2 Limitations
Separation difficulties: PAC's fine particles require additional filtration or sedimentation steps.
Disposal concerns: Spent PAC may contain hazardous adsorbed substances, necessitating regulated disposal or regeneration.
Competitive adsorption: The presence of multiple contaminants can reduce target pollutant removal efficiency.
Powdered activated carbon treatment remains vital for addressing contamination challenges in an increasingly resource-constrained world.
