This thesis focuses on the development of sustainable methods for heavy metal removal from industrial wastewater using advanced adsorption techniques. The presence of heavy metals in industrial wastewater poses a significant environmental and public health risk, necessitating effective treatment methods. Advanced adsorption techniques have emerged as promising strategies for the removal of heavy metals due to their high efficiency and cost-effectiveness. This research aims to investigate and optimize the performance of advanced adsorption techniques for heavy metal removal in industrial wastewater treatment processes. The study begins with an introduction that provides background information on the prevalence of heavy metals in industrial wastewater and the associated environmental impacts. The problem statement highlights the need for sustainable and efficient methods for heavy metal removal, setting the stage for the research objectives. The objectives of this study include evaluating different advanced adsorption techniques, optimizing process parameters, and assessing the feasibility of large-scale implementation. The literature review in this thesis covers ten key areas related to heavy metal removal from industrial wastewater, including the properties of heavy metals, the mechanisms of adsorption, types of adsorbents, and recent advancements in adsorption technology. This comprehensive review sets the foundation for the research methodology, which outlines the experimental design, materials and methods, data analysis procedures, and quality control measures. The research methodology involves laboratory-scale experiments to evaluate the performance of various adsorbents for heavy metal removal.
