The wastewater from textile industry typically containing high alkalify, salts, organic matter, and high color. Textile wastewater is usually treated by anaerobic-aerobic activated-sludge process. The activated-sludge process is effective the reduction of organic matter, but generally does not remove color. Ozone process is one of the most effective process in removal of color for the textile wastewater. Ozone has a strong oxidized dissolution of organism, deceleration, deodorization, fumigation, etc., regarding to water. This study focused on the color removal of textile wastewater. In this study, textile wastewater was treated strongly with ozone at 650mg/hr and the flow rate through ozone contact tank was adjusted to 5L/min. In an application Ozone treatment, Color was generally decreased with time, however, COD removal effect was not that good. In this study, the removal efficiencies of CODcr and Color were 23.5%, 80.4% respectively.
