Comparative study of leachate treatment by coagulation-flocculation process using iron-based coagulants: A case study on Souk-Ahras city

The objective of this study was to evaluate the coagulation-flocculation process inthe clarification of leachate from the landfill Technical Center of Souk-Ahras cityusing three coagulants based on iron: ferrous sulfate FeSO4.7H2O; ferrous chlorideFeCl2.4H2O and ferric chloride FeCl3. The influence...
