RESUMO

For accomplishment of this work was used the technique of eletroflotação for the treatment of effluent of textile industries. A simple reactor was to make with volumetric capacity of 20 liters (ideal for an experimental cell) composite for aluminum plates (kind beehive structure) and a tension source with adjustable power. The method study was with effluent reals, and they were made available by two factory Polyenka and Santista. It points out that the factory discard correctly their effluent, the samples for analysis were left the exit of the dry cleaner s without any previous treatment. The methods and procedures used to the treatment of the effluent in the factory Polyenka, the one that introduced the best results involved time of treatment 40 minute. In this time, it got the turbidity reduction of 151 UNT for 20 UNT, in other words, of 86,7%, the pH increase 7,55 to 9,20. The temperature during the treatment varied 5ºC, reduction of organic material in 93,6% and inorganic in 64%, compared to the effluent in natura, also there was a significant reduction of 90% of DQO and of 99% in DBO. In the factory Santista a turbidity reduction from 4004 UNT to 146 UNT, pH 10,58 was to 11,10 and concluded in 10,56. The temperature belonged from 20,0 to 57,0 ºC a variation of 37ºC. TOC reduction of 30% regarding the effluent ?in natura?. The environment, whith process does not use any chemical product, only electric power, such process becomes very interesting due to the high efficiency in the total removal of the coloration of the effluent in little time of treatment and by the analyses of sobrenadante, it verifies a significant removal of organic material and without the utilization of chemical products being ecologically correct
