Dye wastewater is considered pollutant because it may contain polyaromatic substances known as carcinogenic, mutagenic and teratogenic to a variety of living species. Within the many treatment methods, the electrocoagulation/electroflotation method has been widely studied and it is known to be very effective. However, there is currently no industrial use of it in Colombia, and it is not a priority in academic investigation either. Because of this, this work is an exploratory study of the treatment of printing dye wastewater through the electrocoagulation/electroflotation method. A 22 with a central point experimental design was applied. Removal percentage of OCD (Oxygen Chemical Demand) of the wastewater was obtain between 10,43% and 50,93%. Nevertheless, results show that decontamination through this treatment method may be reversible, and the expected incidence of factors is not observed.
