Textile mill effluents have a complex composition and even after biological treatment, they still contain highconcentrations of dyes and pigments. Activated carbon adsorption has been widely studied for dye removal;however, most studies use synthetic wastewater instead of real textile mill effluent. The objective of this studywas to evaluate the efficiency of color and COD removal from a real textile mill effluent using powderedactivated carbon (PAC). The iodine number was measured to characterize the PAC used. The textile effluentcolor was measured be the ADMI method. The maximum removal efficiency reached was 60% for COD,and 93% for color, using 20g.L?1of adsorbent. Furthermore, with a PAC concentration of 4g.L?1, it waspossible to reach the legal color limit for Minas Gerais, Brazil. The results proved the feasibility of usingPAC for color e COD removal from real textile industry.
