Treatment of Pharmaceutical Wastewater by Potassium Permanganate

Abstract

In order to explore the effectiveness of potassium permanganate for real wastewater treatment, a pharmaceutical wastewater was subjected to the treatment by potassium permanganate. The effect of reaction time, dosage of potassium permanganate, solution pH and ultraviolet irradiation was investigated. The results indicated that there was an optimal reaction time and potassium permanganate dosage. The COD removal efficiency achieved the highest at pH 7.0. Ultraviolet irradiation was proved to be capable of assisting the removal of organic pollutants.

Phenol Removal from Water with Potassium Permanganate Modified Granular Activated Carbon

“…As an oxidant, potassium permanganate has been widely used in water treatment [30][31][32][33][34][35]. In this paper, activated carbon was modify with potassium permanganate, and with representative organic matter of phenol, the impact of modification on adsorption capacity of activated carbon was studied.…”
