Summary
Lectures summarize the different methods of cleaning industrial wastewater and process solutions according to their predominant pollution. The focus of the study is asked to process sewage characteristics, suitable for various types of wastewater. The course emphasis is placed on designing different versions of specific industrial wastewater treatment (in excercises).
Learning Outcomes of the Course Unit
Summarize methods of treating industrial waste water by various industries. Discuss new technological processes of industrial wastewater treatment methods, including electrochemical and membrane processes.
Design modification options effluent treatment.
