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