Abstract

The textile industry for make use of large water volumes in the process of manufacture and processing of tissue is responsible for a considerable load of effluent containing a diverse amount of different contaminants, either dyes or of the various products used throughout the whole process of production, fact that requires adequate and efficient treatment of effluents in order to meet the sanitary standards legal and to ensure the continuity of industrial activity. There are several methods for treating effluents from the textile industry, however, the treatment efficiency is better if different methods are used, since the method used for the removal of the color often does not guarantee success in removal of other substances contained in the effluent such as the gas which cause bad smell. This study aimed to highlight the method of treating textile effluents most used by industry segment. Achieved this goal with the realization that the methods used in the textile industry are the processes related to activated sludge.
