In the current study, two types of filters made from sustainable natural materials—one containing natural cellulose and the other having natural nanocellulose—were used to remove cadmium from contaminated water. Polyethylene containers were used to gather samples of contaminated water from the Hilla River. Three separation columns (250 ml) and (5 cm diameter) were used to conduct the first and second experiments filled with natural cellulose and nanocellulose, respectively, and the third filled with a mixture of both. In two stages, the first, three separation columns were filled to a height of 6 cm and at flow rates of 100 ml and 250 ml per minute. In the second stage, the height of the materials was 12 cm and at the same flow rates. The study›s findings demonstrated cellulose and nanocellulose may remove cadmium, their efficacy varies. In both stages, the maximum percentage of pollutant removal was seen in the second separation column. The findings of the present investigation also shown a correlation between the velocity at which contaminated water passes through the filters in the separation column and the clearance rate. The statistical analysis results at the probability level of P≤0.05 clearly indicate the existence of a substantial inverse association between the flow rate and the removal rate
