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. While operational hurdles persist, ongoing research into material science and process engineering promises to elevate PAC's efficacy and environmental compatibility. As industries and municipalities strive to meet stringent sustainability goals, PAC will play a pivotal role in safeguarding water, air, and public health.

Water purification is a critical process for ensuring safe drinking water, industrial use, and environmental protection. Among the many filtration technologies available, activated carbon stands out as a versatile and effective solution.
Activated carbon, also known as activated charcoal, is a highly porous material derived from carbon-rich organic sources such as coal, coconut shells, or wood. Through a controlled activation process—often involving high-temperature steam or chemical treatments—the carbon develops a vast network of microscopic pores. This structure grants it an exceptionally large surface area (up to 1,500 square meters per gram), making it ideal for adsorption, the process by which contaminants adhere to its surface.
When water passes through activated carbon, contaminants are trapped via two primary mechanisms:
1. Physical Adsorption: The porous structure acts like a sponge, capturing particles such as sediment, organic compounds, and microorganisms.
2. Chemical Adsorption: Charged molecules, such as chlorine, pesticides, and volatile organic compounds (VOCs), bond to the carbon’s surface through electrostatic interactions.
Activated carbon is particularly effective at removing chlorine, bad odors, and organic pollutants. It also reduces heavy metals like lead and mercury by attracting their ions. However, its efficiency depends on factors such as contact time, pore size distribution, and the chemical nature of the contaminants.
- Granular Activated Carbon (GAC): Used in large-scale filters for municipal water treatment or home systems. Its loose granules allow water to flow freely while maximizing contaminant contact.
- Powdered Activated Carbon (PAC): Added directly to water in treatment plants for rapid adsorption of specific pollutants.
- Carbon Block Filters: Compressed carbon particles create a dense filter medium, often combined with other materials (e.g., silver) to inhibit bacterial growth.
Activated carbon filtration is widely used in:
Drinking Water Purification: Removes chlorine, improves taste, and eliminates harmful organic compounds.
Wastewater Treatment: Addresses industrial pollutants like dyes, pharmaceuticals, and hydrocarbons.
Aquarium and Pool Systems: Maintains water clarity and neutralizes toxins.
For complex contamination, activated carbon is often paired with technologies like reverse osmosis or UV sterilization to achieve comprehensive purification.

Activated carbon filtration is a highly effective purification method widely used to remove contaminants, odors, and impurities from air and water. By leveraging the adsorptive properties of activated carbon, this technology plays a critical role in industries ranging from water treatment to air purification and beyond.
Activated carbon, also known as activated charcoal, is a porous material treated to increase its surface area and adsorption capacity. During filtration, contaminants in fluids or gases are trapped within the carbon’s microscopic pores through a process called adsorption. This occurs when molecules adhere to the carbon surface due to chemical attraction or physical forces. Activated carbon’s effectiveness depends on factors like pore structure, raw material, and activation methods.
Activated carbon is categorized based on its source material, physical form, and specialized treatments. Below are the most common types:
Granular Activated Carbon (GAC)
GAC consists of irregularly shaped particles ranging from 0.2 to 5 mm in size. It is ideal for water filtration systems, such as municipal treatment plants and home water filters, due to its high flow rate and capacity to adsorb organic compounds, chlorine, and volatile organic compounds (VOCs).
Powdered Activated Carbon (PAC)
PAC features finely ground particles (less than 0.18 mm) and is often used in wastewater treatment and emergency contaminant removal. Its small particle size provides a large surface area for rapid adsorption but requires containment systems to prevent leakage.
Carbone attivo impregnato
This type is infused with chemicals like iodine or potassium to target specific pollutants. For example, silver-impregnated carbon inhibits bacterial growth, making it suitable for medical and air purification applications.
Activated Carbon Fiber (ACF)
ACF is woven into fabrics or felts, offering flexibility and superior adsorption kinetics. It is commonly used in industrial gas masks, solvent recovery, and air filtration systems where lightweight, high-efficiency materials are required.
Coconut Shell-Based Activated Carbon
Derived from coconut shells, this eco-friendly variant has a dense microporous structure, excelling in removing chlorine and organic contaminants from drinking water.
