Course/Module description:
Understanding conventional and advanced physical, chemical, biological processes related to water, municipal and industrial wastewater treatment and water reuse.

Course/Module aims:
To impart to the student, knowledge on water and wastewater treatment and reuse processes which help to preserve human health, soil and water resources

Learning outcomes - On successful completion of this module, students should be able to:
On successful completion of this course the student should be able to understand:
a. The nature of impurities in waters and wastewaters.
b. The basic principles of conventional and advanced treatment processes in water and wastewater treatment and reuse.
c. Select appropriate processes depending on the nature of impurities to be removed and the intended use of the treated water or effluent.

Attendance requirements(%):
At least 80-90% of the time. Full attendance required for the technical visits day

Teaching arrangement and method of instruction: Frontal teaching by presentations which will be previously posted in the course web site. Two assignments and two problem solving sessions (water, wastewater), one technical visits day, written report on the technical visit day learning, end of year written exam (closed book multiple answers part, open book problem solving part).
