Application of Electrodialysis Process for Reduction of Electrical Conductivity and COD of Water Contaminated By Composting Leachate

Nazila Parsa, Golnoosh Khajouei, Mohammadali Masigol, Hasti Hasheminejad, Ahmad Moheb
2018 Civil Engineering Journal  
Along with evaluation of ED method for desalination, the possibility of the process for COD (chemical oxygen demand) removal was also studied.  ...  Increasing of the applied voltage and decrease of feed concentration enhanced the reduction of EC and improved the COD removal from the sample.  ...  Also, because of not very high COD reduction efficiency (50%) obtained with electrofenton method, along with EC, COD reduction during ED process was evaluated.  ...
