Electro-Fenton process could remove pollutant in in tannery industry wastewater. The objectives of this is used to know the effect of electro-Fenton on, ammonia (NH3), chromium (III) (Cr(III), total suspended solid (TSS), biological oxygen demand (BOD), and chemical oxygen demand (COD) removal in tannery wastewater treatment. The voltage variation used to trigger the electro-Fenton reaction was 6 V, 8 V, and 10 V. Observation time at 0, 30, 60, 90, and 120 mins was used to see changes in the sample. The results obtained are electro-Fenton method has an effective time of 30 mins to removal efficiency of 60.7%, 32.9%, 72.8%, 53.4%, and 53.4% for NH3, Cr(III), TSS, BOD, and COD respectively. Pollution from tannery effluent can be eliminated to a sufficient extent using the electro-Fenton technique.
