1. Crystallization
Individually during an oral examination: short questions/answers on the course material, without preparation.
2. Other fluid-solid separation techniques :
- Individually or in small group: results presentation, quality of the expression during the presentation of the design project for an industrial filtration unit and ability to answer the questions.
- Individually during an oral examination on the course material, with written preparation.
1. Crystallization :
In 3 lectures of 2 hours by the course teachers.
2. Other fluid-solid separation techniques :
- In 11 lectures of 2 hours by the course teachers.
- The addressed theoretical notions will be illustrated through case studies of different filters types. Those studies will include the characterization of the liquid to be filtered eventually lab trials and the sizing of the filter; Students are invited to present their results to the group.
