Course objectives

Students gain knowledge about the basic unit operations in the environmental engineering through theoretical expressions based on the mass and energy balances. Students are also acquainted with the working principles of the most used devices and selection of their optimum working conditions regarding minimization of energy consumption and environmental protection.

Course enrolment requirements and entry competences required for the course

Enrolled in or passed the course Exercises in Unit Operations in Environmental Engineering
Enrolled in or passed the course Exercises in Transport Phenomena
Enrolled in or passed the course Transport Phenomena

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam the student is expected to know:
- fundamental principles of mechanical and of heat and mass transfer operations,
- explain the laws that follow performance of individual operation,
- explain the influence of operating variable on individual operation applied in the environment protection,
- explain the working principle of the most common used equipment for particular operation,
- bring up possible operating problems that may occur during operation performance.
