Production of oxidants during the electrical discharge in a foaming environment is confirmed. The influence of electrical discharge on the removal of color caused by various organic compounds such as ethyl violet, humic acid, indigo blue, and methylene blue in the foaming apparatus has been investigated. Discoloration is observed visually and concentrations of pollutants have been measured, which include the influence of the type of gas, gas flow rate, and frequency on the removal rate.
