with processes such as coagulation, adsorption, ion exchange, and oxida-
tion/reaction for best overall results on effluent treatment.

2.6 COST CONSIDERATIONS
Coagulation processes have immense potential for removal of both pollutants
and color, and, to a large extent, can be effectively employed for removal of
