dewatering, preheating and calcination. In dewatering of Nanoparticle slurry, performances of both filtration_x000D_
and thickening are affected negatively. Nanoparticles reduce performance or block porous space inside filter_x000D_
cloth. Therefore, filtration should be done as a batch process with low performance. Also, nanoparticles cause_x000D_
serious problems for thickening operation including slow particle settling, increase in residence time, and_x000D_
bigger flocculant consumption. For a pigment slurry, low power microwave treatment can be used as a_x000D_
substitute for filtration, and work with or without thickener. Microwave application for calcination is more_x000D_
complicated compared to dewatering, because it is expected to generate higher temperatures as well as improve_x000D_
physical phase transformation. This research work will focus on microwave-assisted dewatering and_x000D_
calcination. Argex Titanium Incorporated, is developing a novel technology for producing titanium oxide_x000D_
pigment. Preheating, dewatering and calcination stages are part of the production line. Therefore,_x000D_
microwave-assisted heating can be used for these preheating and dewatering and calcination. Developing this_x000D_
novel microwave-assisted thermal treatment technique will lead to less energy consumption, better control on_x000D_
the process and higher process efficiency for Canadian pigment industry the advantages of which will increase_x000D_
the profitability of the pigment plant., program purpose french : Pigment production has thermal treatment stages that can substituted by microwave radiation such as_x000D_
