Climate change, drought are expected to have severe consequences on the livelihoods of millions of people around the world, but its effects will not be evenly distributed [1]. Wastewater discharge from textile industry cause an environmental problem mainly in terms of COD and color. Treating dyeing effluent is a major economic and environmental issue to reduce the effects of drought and reuse water. The textile effluent color and organic load reduction by adsorption using dynamic regime, was evaluated by decantation and coagulation-flocculation pretreatments. The feasibility of each of the two processes was studied separately and their operating parameters were optimized
