Electroflotation (EF) with aluminum electrodes was applied in the treatment of Brazilian industrial coconut wastewater. The results show that EF with polarity inversion is a very good treatment when compared to others. The removal of pollutants in the wastewater after EF with polarity inversion was 96.3% of oils and grease, 99% of color and 66% of total organic carbon. Also, metal concentrations, turbidity and total solids were reduced.
