Wood Based Unwashed Powdered Activated Carbon
Wood based unwashed powdered activated carbon retains some soluble impurities and fines due to the absence of the washing process. Despite these impurities, it has numerous applications where ultra-high purity is not as critical, and cost considerations are paramount.

Applications
Wood-based unwashed powdered activated carbon provides a cost-effective solution for many applications where the presence of some impurities does not significantly impact the process or product quality. Its use is particularly advantageous in large-scale or industrial applications where the cost savings outweigh the need for the highest purity levels.
Water Treatment
Basic Drinking Water Purification: Suitable for less stringent water treatment needs where slight impurities from the PAC will not significantly impact the water quality.
Wastewater Treatment: Used in municipal and industrial wastewater treatment plants to remove organic contaminants, dyes, and heavy metals.
Air and Gas Purification
Industrial Air Filters: Employed in air filtration systems to adsorb volatile organic compounds (VOCs), odors, and other industrial pollutants.
Gas Purification in Industrial Processes: Used to remove impurities from gases in various industrial processes, where absolute purity is not a priority.
Food and Beverage Industry
General Purification: Applied in the purification of less sensitive food and beverage products to remove color and odors, improving overall quality without requiring the highest purity levels.
Environmental Applications
Soil Remediation: Used in soil remediation projects to adsorb organic contaminants, helping to restore contaminated land to a usable state.
Oil Spill Cleanup: Effective in adsorbing oil and other hydrophobic substances during environmental cleanup efforts.
Industrial Applications
Effluent Treatment: Used in treating industrial effluents before discharge to meet environmental regulations by removing harmful chemicals and pollutants.
Process Water Treatment: Applied in treating process water in industries like textiles and paper manufacturing to remove contaminants that could interfere with production.
Agricultural Applications
Pesticide Removal: Used to remove pesticide residues from water used in agriculture, ensuring safer irrigation water for crops.
Animal Feed Additive: Sometimes included in animal feed to adsorb toxins and improve gut health in livestock.
Chemical Industry
Catalyst Support: Used as a support material for catalysts in certain chemical reactions, where minor impurities do not significantly affect the catalytic process.
Bulk Chemical Purification: Suitable for bulk chemical purification where high-purity PAC is not necessary, reducing costs.
Cosmetic and Personal Care
Basic Skin Care Products: Used in less premium skincare products where the primary goal is to adsorb excess oils and impurities from the skin.
Energy Sector
Biogas Purification: Utilized in the purification of biogas to remove contaminants such as hydrogen sulfide and siloxanes, making it suitable for use as a fuel.
Coal and Biomass Gasification: Helps in purifying the gas produced from coal and biomass gasification processes by adsorbing impurities.
Textile Industry
Dye Removal: Used in the treatment of textile wastewater to remove dyes and other organic pollutants, helping to minimize the environmental impact of textile production.
