Topics

• Water quality: physical, chemical and biological characteristics LO1–2
• Natural processes: dilution, sedimentation, stratification, eutrophication LO3, LO5
• Gas transfer and the dissolved oxygen model LO4
• Reactor analysis, mass balances, kinetics of biological growth, hydraulic profiles LO6
• Wastewater treatment: preliminary to tertiary, sludge LO7–9

3. Analyse degradation of organic matter in a watercourse over time
4. Calculate the dissolved oxygen sag below organic pollution
5. Estimate the effect of phosphorus loading on eutrophication
6. Apply reactor design to water and wastewater treatment
7. Size water and wastewater unit processes, with energy, chemicals and by-products
8. Know the legislative and health context of water treatment
9. Design a wastewater treatment plant from flow and load data
10. Identify air pollutants and analyse their dispersion from point sources
