Language of instruction



Separation and purification processes are used in a wide range of industries on field and off-field. Solid-liquid, gas-gas and liquid-liquid separation techniques are under active investigation by researchers all over the world towards efficient separation and purification. The course will cover both fundamental and applied aspects of solid, gas and liquid separations; and additional biological separation at molecular level, a broad spectrum of activities from lab scale to pilot plant to full-scale plants, through laboratory investigations and theoretical studies. The course offers available and practical methods for efficient separation and purification from various suspensions, membrane filtration, cell rupture, phase separation technologies and electrical separation techniques. In addition new or improved separation & purification methods or principles on biotechnology, biobased feedstocks/products, green technology with respect to resource recovery and recycling will be covered.

Fundamental theory and applied aspects are linked to provide new insights, and to indicate new and innovative ways of solving practical problems of the current industries. Discussion on various industrial cases and new perspective/opinion will help to understand remaining uncertainties. Extensive references and case studies will encourage further studies in the field.

Learning outcome

This subject introduces fundamental terminology, basic analysis and applications of the principles of various separation and purification technologies.

Students will be able to understand and analyze theories and case situations in which unit processes are to solve problems within the field of environmental engineering and applied biotechnology. Knowledge gained provides students with a basis to understand and contribute to the development of novel techniques and applications.

Course assessment

There must be an early dialogue between the course coordinator, the student representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital course evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
