Treatment of Low Level Phenols (μg/L) with Potassium Permanganate

Abstract

Laboratory and field studies demonstrated the viability of potassium permanganate oxidation of phenols in meeting federal pretreatment standards. This oxidant was applied to wastewater from a resin manufacturer and an aluminum caster. Results from a field study at the resin manufacturing plant indicate that discharges of less than 19 μg/L are achievable. The aluminum caster consistently achieved phenol discharges of less than or equal to 5 μg/L. The impact of manganese dioxide on discharge color was also evaluated. It was found to be the principle contributor to color formation. Laboratory data indicated that an improvement in the turbidity of wastewater samples previously treated with potassium permanganate was possible. This was accomplished with properly administered flocculation aids.
