Abstract

Water is indispensable for life and economic development. The current pronounced water scarcity promotes the search for sustainable consumption and reuse of water. No less important is the pollution of water resources by the discharge of effluents from various types of industries, such as textiles, dairy, food, among others. In this sense, this work aims to evaluate the efficiency of textile wastewater clarification through the use of iron chloride and aluminum sulfate coagulants. For this purpose, synthetic samples of textile wastewater were formulated and diluted in aqueous kaolin and textile dye in different concentrations. The coagulants were added in different dosages by jar test. The results obtained varied according to the concentration of pollutants, and the aluminum sulfate showed better clarification efficiency, achieving adequate values of turbidity and pH in the dye/kaolin proportions1:3 and 2:2 (m/m). Ferric chloride showed best results of these parameters at dye/kaolin proportion 2:4 (m/m).
