Managing water resources, treating wastewater effectively, and addressing the diverse range of pollutants are critical for achieving sustainable development and ensuring a clean water supply for the growing global population. Heavy metals are widely recognized for their toxicity to living organisms. These metals pose a threat due to their bio-accumulative nature and high solubility in aquatic environments. Human exposure to heavy metals through ingestion, inhalation, and dermal contact poses severe health risks, affecting vital organs and leading to diseases like muscular dystrophy and cancer. It is crucial to manage and treat wastewater effectively to reduce heavy metal concentrations and protect human well-being. Remediation techniques for heavy metals contamination include phytoremediation, bioremediation, chemical precipitation, coagulation and flocculation, ion exchange, electrochemical techniques, membrane, and adsorption. In the pursuit of effective heavy metal removal from wastewater, various methods have emerged, each offering distinct advantages. The choice of technique depends on factors like the type and concentration of heavy metals, site characteristics, and environmental and economic considerations. A combination of these methods may be utilized for effective remediation, focusing on proper waste disposal and compliance with regulatory requirements.
