The Dependence of Ethylene Glycol Decomposition on Initial Concentration in the Water Treatment using Pulsed Streamer Discharge in Air

We have studied the water treatment by pulsed power discharge in water droplets spray in air. Ethylene glycol was used for sample. The dependence of decomposition of ethylene glycol on initial concentration was investigated. It was found that intermediate product was generated by decomposing process of ethylene glycol. In the concentration of 50 mg/L, whole ethylene glycol was decomposed by water treatment for 4 hours. However whole intermediate product wasn't decomposed in 4 hours treatment. In the concentration of 25 mg/L, ethylene glycol and intermediate product were decomposed in treatment time at 4 hours.
