Résumé:
The objective of the present study is to see the difrence between traditional physicochemical
process such as chemical coagulation and electrocoagulation process treating a Landfill Leachate
effluent.
As it's known Leachate is difficult to treat to meet to the discharge standards for its variable
composition and proportion of refractory materials.
We used Jar test experiments for chemical coagulation, Aluminium sulphate (Al2(SO4)3,10 H2O) as
a coagulant, we also perform to compare the removal efficiencies of different pollutants as phenol,
nitrate and total organic carbon for each method.
Experimental results of electrocoagulation using an aluminum electrode with a current density of
166.6 A/m2 and a residence time of 150 min have shown its important removal capacity as total
organic carbon and turbidity were 78.24% and 98 % consecutively, who were better than chemical
coagulation results.
Furthermore, it can be concluded that the electrocoagulation technique
