Water pollution by heavy metals has been a serious threat to health and the environment worldwide due to toxic, bio accumulative, and persistent nature of heavy metals. The use of advanced treatment methods for heavy metals is limited in countries like Sri Lanka due to the high cost of treatment and lack of advanced technologies. Therefore, this research was conducted to study the potential of using sludge-based materials to remove heavy metals from wastewater, factors affecting the adsorption, and mechanisms of adsorption of heavy metals. The findings of the research can be used to develop a sustainable, cost effective, efficient, and environmentally friendly method to treat wastewater contaminated by heavy metals.
