PENURUNAN KONSENTRASI COD DAN FENOL AIR LUMPUR LAPINDO DENGAN METODE OKSIDASI FENTON DAN UV

Abstract

This research was carried out to investigate the removal of COD and phenol sludge filtrate by Fenton oxidation and UV after the treatment of coagulation-flocculation-sedimentation. Variation of treatments included UV intensity, H₂O₂ and FeSO₄ concentration, and illumination time was 3 hours. The results showed that 92,71 %  of COD removal and 100% of phenol removal (undetectable phenol) occurred at 36 Watt of UV, 250 mg/L of H₂O₂ and at 36 Watt of UV, 500 mg/L of H₂O₂. While 84,24% of COD removal occurred at Fenton variation of 500 mg/L of H₂O₂ : 100 mg/L of FeSO₄  and 72 watt of UV light. Phenol removal of 98,84 % occurred at Fenton variation of 500 mg/L of H₂O₂ : 100 mg/L of FeSO₄.  and 36 watt of UV light.
