Carbon Adsorption Applications

  • Solutions for recovering metals

    The mining industry relies on Calgon Carbon’s Granular Activated Carbon (GAC) to recover gold and other precious metals. Calgon Carbon’s ISEP® Technology is used to recover precious, rare earth and base metals, uranium, copper, nickel and zinc from ore, waste and reclaim streams. Our high-quality activated carbons have been developed and successfully proven to maximize efficiency by reducing the loss of precious metals and the consumption of carbon in three precious metal extraction techniques: Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Carbon-in-Column (CIC). When Ion Exchange is employed for metal recovery in leach and waste streams, Calgon Carbon’s ISEP ® system provides a continuous, consistent and high purity concentrated product while minimizing the use of chemicals, resin and wastes. Calgon Carbon’s continuous ion exchange systems are the most flexible, robust, and accepted in the industry.

  • Removal of organic compounds & toxity for wastewater treatment industry

    Federal and State regulatory agencies are increasingly requiring additional water quality testing and controls of the toxicity of discharges to receiving streams. Granular Activated Carbon (GAC) helps meet these pollution regulations. If organic chemicals have been identified as contributing to discharge toxicity, Calgon Carbon Corporation can work with facilities, and their engineering firms, to help meet stringent criteria associated with their NPDES permit. GAC can be employed as a cost-effective treatment for removal of organic compounds and toxicity. Even in situations where activated sludge treatment or powdered activated carbon is used for primary wastewater treatment, post treatment with GAC may be necessary to achieve toxicity compliance.

  • Drinking water solutions for the TOC removal efficiency

    Problem: Organic matter (UV254/TOC) in drinking water can react with chlorine to form harmful disinfection by-products (DBPs). Some removal of TOC is achieved through the conventional drinking water treatment processes, while carbon absorption may be used to further enhance the removal of TOC prior to chlorine disinfection.

    Advanced water treatment equipments for hydrogen sulfide removal

    The presence of hydrogen sulfide in home drinking water supplies is not a health hazard, but is a common nuisance contaminant whose distinctive `rotten egg` odor makes water treatment desirable. Several treatment methods are available, and often hydrogen sulfide can be treated and removed using the same process and equipment used for iron and manganese removal.

    Hazardous waste treatment solutions for chlorine industry

    The mercury cell process is a formerly widely-used production technique for the production of chlorine and caustic soda. The liquid metal, mercury, acts as cathode (negative pole) in this process. In the past, the loss of mercury during the process (to air, soil and water) led to serious health and environmental problems. Therefore, most European chlorine producers have decided to phase out the mercury cell process by 2020. Nevertheless, even today, almost 6000 tons of mercury is used per year for chlorine production in Europe alone. As a result of this, yearly waste outputs contain around 1200 tons of mercury, which are stored on-site or sent off for disposal.
