Heavy metals like copper, chromium, cadmium, lead, and zinc are key contaminants of freshwater reservoirs because of their deadly, non-biodegradable, and persistent nature. The work involves the comparison of various single and combined processes such as ozonation (Ozo), adsorption on activated carbon (AC), adsorption on rice husk (RH), ozonation in the presence of rice husk (Ozo/RH) and ozonation in the presence of activated carbon (Ozo/AC) for the removal of chemical oxygen demand (COD) and…
