poses a significant challenge for treatment via conventional wastewater treatment facilities. Leachate contains_x000D_
high amounts of organic matter, inorganic macro-components, heavy metals, and many other hazardous_x000D_
chemicals. High concentrations of ammonia nitrogen (AN) in leachates poses a substantial toxicity risk to_x000D_
adjacent surface and groundwater sources and necessitates proper treatment of these leachates to meet local_x000D_
standards for safe disposal or reuse. Electrochemical advanced oxidation processes (EAOP) like_x000D_
electro-oxidation (EO) and electro-coagulation (EC) could serve as a useful means to treat leachates originating_x000D_
from MSW landfills. In EO, the direct action of electric current is used to oxidize or reduce species exclusively_x000D_
at the electrodes, which convert toxic and/or biorefractory pollutants into more benign chemicals. On the other_x000D_
hand, EC involves the generation of coagulants in situ by electrically dissolving metal ions (aluminum or iron)_x000D_
at the anodes. These coagulants quickly form large particulate flocs, which in turn chemically adsorb pollutants_x000D_
from wastewater. The combination of these two EAOPs into a single electrolytic cell is expected to_x000D_
demonstrate excellent potential for the removal of AN from high strength leachates. Since these processes do_x000D_
not require the addition of any chemicals from external sources, they can be considered as "clean" technology._x000D_
The outcomes of this project will significantly add value for the company, GHD, and Canada in general. In_x000D_
effect, this project aims to develop practical solutions for the treatment of high-strength leachate and preserve_x000D_
the quality of our environment. Although existing treatment technologies easily remove the organic load from_x000D_
leachate, the removal of ammonia presents a significant challenge. The proposed hybrid EO-EC system is_x000D_
expected to reduce a substantial portion of the ammonia and organic load from high strength leachate. The_x000D_
process will also eliminate the need for chemical inputs and will enable the design of compact reactors in a_x000D_
small area to treat high-strength wastewater., program purpose french : High-strength wastewater generated from municipal solid wastes (MSW) landfills, also known as leachates,_x000D_
