Upon successful completion of this course the students will acquire new knowledge and specific skills on the following subjects and will be able to:

• Analyze existing and design new Physical Separation Processes for the Chemical Industry (raw material and product processing units) or for waste treatment plants (gaseous emissions or wastewater).
• Understand in depth the processes of physical separation and to be able to choose the best available technology per case.
• Optimize the performance of already installed separation processes or to carry out re-engineering actions.
• Have solutions for a variety of problems for the treatment of environmental pollution, the improvement of the quality / purity of the products produced in the chemical industry.

• Review, analysis and synthesis of data and information, with the use of necessary technologies
• Project design and management
• Work in interdisciplinary environment
