Doehlert experimental design for the optimization of electrocoagulation treatment of landfill leachate

The treatment of a mature landfill leachate has been studied by the electrocoagulation process using aluminum electrodes. In this study, Doehlert experimental design was applied for the determination of the optimal operating conditions. The results were evaluated through the construction of isorespo...
