Removal of Organic Pollutants from Reverse Osmosis Concentrate by Electro-Fenton Process

Abstract:

The RO concentrate containing non-degradation organic pollutants was treated by electro-Fenton process. The high voltage pulse generator was used as discharge power. The effects of pulsed electric field parameters, aeration rate and pH on COD removal rate was investigated. The results indicate that the COD removal rate is up to 80.71% when pulsed voltage, pulsed frequency, treatment time, aeration rate and pH are 30000 V, 5 Hz, 240 s, 1.0 m3/h and 10, respectively.
