This work is devoted to a multi-scale study of the electrochemical cells applied in the electrodeposition process. The first part concerns with macroscopic model of a batch reactor used for copper depollution. The second part relates to the experimental study of current distributions in a rotary Hull cell and in a modified Mohler cell. The third part deals with the development of a reaction path mechanism relating to the zinc-nickel alloy codeposition resulting in the model of this operation. This work led to a set of tools particularly useful and powerful for the development of a new electrodeposition plant, especially applied for the design and the process control more than the management of the baths.
