The effluent of a rubber chemical antioxidant and antiozonant producer industry, with high content of organic material was subjected to electrolytic process. To evaluate the speed of stabilization of the eletroctrolyzed effluents, and to evaluate the biodegradation the respirometric test of Bartha and Pramer was used. The monitoring of the biodegradation of the effluent, after different periods of electrolysis show that the ideal time of electrolysis was 10 and 25 min. It was concluded that the eletrolytic process was viable to diminish the adaptation time of the microorganism to the effluent and consequently increased the biodegradation of effluent.
