To complete these tasks within a period of 12 weeks, students must provide a log book to record the activities, analysis of the problems and making the proposals; case studies; laboratory work to analyse pollution parameters, and the proposed technological solutions to the problems. The laboratory work was limited to three or four pollution
parameters such as Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), etc. Students were required to write a short laboratory report and answer questions related to the laboratory experiments. Laboratory experiments were supervised by the lecturer concerned, a science officer, and three laboratory assistants.
