Abstract

River water sea water mixing experiments were carried out to study the time dependence of flocculation process, teh flocculation behaviour of dissolved Cu, Pb, Zn , Ni Co, Mn Cr and Fe in the kali estuary. Flocculation appears to be maximum at high salinitics (>25%) and is rapid, about 7 to 60% of the dissolved metal content floccularing with half an hour of mixing. This brings out the role of sea water as a poerful flocculating agent for the dissolved load of river water.
