Experimental design approach to COD and color removal of landfill leachate by the electrooxidation process

Toxic leachates originate from landfills are one of the major environmental problems. It has an important role in groundwater contamination and its treatment is crucial for environmental protection. In this research, the Electrooxidation (EO) process is applied to the landfill leachate balancing poo...
