Activated Carbon
A porous carbon adsorbent used to remove organics, colour, taste, and odour from liquid and gas streams.
Activated carbon (also known as activated charcoal) is a highly porous material made from carbon-rich substances like wood, coal, or coconut shells. It is “activated” through a heating process that increases its surface area and porosity, enabling it to adsorb (trap) impurities, gases, and chemicals. Due to its large surface area, activated carbon is commonly used for filtration, purification, and detoxification in applications such as water treatment, air purification, and medical treatments (like poison ingestion). Its ability to adsorb contaminants makes it effective in removing odours, heavy metals, and organic compounds.
Coal-based activated carbon is a highly effective adsorbent produced from premium coal through carbonization and activation. Its porous structure greatly increases surface area, making it ideal for diverse applications. It is widely used in water and air purification, industrial waste treatment, gas adsorption, and as a catalyst carrier. Its effectiveness also extends to decolorizing and purifying chemicals in various industries.
Coconut shell activated carbon is a premium adsorbent produced from natural coconut shells through carbonization and activation. Known for its hardness and high density, it offers superior adsorption capacity, making it ideal for water and air purification. Its micro-porous structure effectively removes impurities, contaminants, and odours. Widely used in gold recovery, food processing, and pharmaceuticals, it provides high purity and effectiveness. Environmentally friendly and renewable, coconut shell activated carbon is a sustainable choice for various industrial and commercial applications, ensuring enhanced performance and cleaner environments.
Powdered Activated Carbon (PAC) has a diameter under 0.1 mm and an apparent density of 0.37-0.74 g/cm³. Characterized by iodine and molasses numbers indicating pore volumes, PAC meets AWWA standards with a minimum iodine number of 500, ensuring high adsorption efficiency for water treatment, air purification, and industrial applications.
Activated carbon pellets are cylindrical particles created from high-quality carbon sources through a process of activation. These pellets offer a large surface area and uniform porosity, making them highly effective for gas and liquid phase adsorption. Commonly used in air and water purification, they efficiently remove impurities, odours, and contaminants, offering a durable and low-dust solution for various industrial applications.
Activated carbon granules are coarse, granular particles made from carbon-rich materials like coal or coconut shells. They have a high surface area, providing excellent adsorption properties for removing impurities, odours, and contaminants from gases and liquids. Widely used in water treatment, air purification, and industrial processes, activated carbon granules are effective, durable, and cost-efficient.
