Description :
Heavy me tals are toxic to aquatic organisms and also to human beings. Generally heavy metals are
discharged from industries or factories to the nearby water bodie s. Due to this organic load also increases. Many
adsorbent has been used to remove toxic me tals and organic load from waste water. There fore it is essential to search
some alternate adsorbent which is economical feasible. In this study Red mud is used as an adsorbent for the
removal of metals and organic load from the waste water. Red mud is a waste product generated during the extraction
of aluminium from the bauxite.
It has been observed that Red mud has good adsorption capacity. Laboratory scale experiment shows that
cadmium metal and organic load were removed using Activated Red Mud (ARM). Maximum removal of cadmium
me tal was found to be 85% at pH 8-9.The removal of COD was found to be 69% at pH 6.8.
