68th webinar of the Hebd'Eau series entitled "Characterization and Treatment of Landfill Leachate" by Oumaima El Hachimi
Oumaima El Hachimi is a PhD candidate in water sciences at the National Institute of Scientific Research (INRS-ETE). Her research work focuses on the treatment of complex wastewater effluents by chemical and biological processes. Currently, she is particularly interested in studying the integration of membrane bioreactor systems and electrocoagulation in a one-step process for landfill leachate treatment.
Landfill leachate is a mixture of percolated rainwater, water produced by waste biodegradation, and water inherent in the waste, which contains large amounts of dissolved organic matter, salts, heavy metal ions, and other organic compounds (e.g., chlorinated aliphatics , and pesticides). Leachate from landfills is toxic, presenting potential threats to the environment and surrounding ecosystems. Therefore, it is imperative to develop effective treatment technologies to remove contaminants from leachate.
Various technologies, including biological treatments (e.g., activated sludge and fluidized bed reactor processes), chemical treatments (e.g., Fenton process, chemical precipitation), and physicochemical treatments (e.g., adsorption and membrane processes), for leachate treatment will be presented. In addition, the drawbacks and challenges of current leachate characterization and treatment techniques will be presented.
The presentation will be given in French
