Leather Tannery Wastewater Treatment Using Electro-Fenton Process – Effects on Ammonia, Chromium, Total Suspended Solid, Biological Oxygen Demand and Chemical Oxygen Demand Removal

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 (NH 3 ), 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 NH 3 , Cr(III), TSS, BOD, and COD respectively.Pollution from tannery effluent can be eliminated to a sufficient extent using the electro-Fenton technique.
