In the realm of wastewater treatment, shell activated carbon has emerged as an effective solution for addressing various pollutants. One notable application involves its use in treating wastewater containing phenol. This compound is commonly found in industries like petrochemicals, resins, coke, and refineries. Laboratory tests have demonstrated that activated carbon exhibits excellent adsorption capabilities for phenol. However, higher temperatures tend to hinder this process, reducing the adsorption capacity while slightly shortening the time needed to reach equilibrium. Optimal amounts of activated carbon and ideal contact times exist for maximum efficiency. Interestingly, under acidic and neutral conditions, the removal rates remain relatively stable. Yet, in strongly alkaline environments, the effectiveness drops significantly, with the degree of alkalinity inversely affecting the adsorption performance. Another critical application lies in managing mercury-contaminated wastewater. Shell activated carbon possesses the ability to bind mercury and its compounds, though its capacity is limited and best suited for low-concentration scenarios. For instances where mercury levels are elevated, alternative methods like chemical precipitation should be considered first. Post-treatment, the residual mercury content typically falls around 1 mg/L, though concentrations may rise up to 2-3 mg/L in severe cases, necessitating further processing with activated carbon. Cyanide-laden wastewater presents yet another challenge that shell activated carbon can tackle. Cyanide is utilized in numerous industrial processes, including gold and silver extraction, chemical fiber production, coking, ammonia synthesis, electroplating, and gas generation. Consequently, cyanide often finds its way into effluents during these operations. Chromium-containing wastewater represents another significant issue, particularly in electroplating facilities where chromium is extensively employed. Depending on the pH level, hexavalent chromium manifests differently in wastewater. Fortunately, shell activated carbon’s porous structure and expansive surface area enable it to physically adsorb Cr(VI) effectively. Additionally, functional groups like hydroxyls (-OH) and carboxyls (-COOH) present on the carbon’s surface provide both electrostatic and chemical binding capabilities.
