Treatment of surface water for obtaining water of potable quality is being practiced all over the world. The desludging of water treatment tanks results in discharge of water works waste.On analysis this waste has been found to contain SiO2, Fe2O3,Al2O3,CaO ,MgO,SO42-,Cl-,F- and organic matter as major components. A number of anthropogenic toxicants like heavy metals Cu,Co,Ni,Pb,Zn,Mn,Cd,Bi,Cr,Li,Rb,As,Si,Sb,and F- which were in the raw water at trace level were found to have accumulated in the water works waste in concentration several fold higher than in the raw water. Experiments showed that this waste has asignificant adsorption capacity for removing several toxic ions and shows promise as a good detoxifying material.
