The aim of the module is to advance students’ knowledge in water resources engineering including the main systems, unit operations and processes in urban wastewater treatment, and their principles, analysis, process design and operation.

Learning outcomes 
A. Identify the main systems and the principles of unit operations and processes in urban wastewater treatment.

B. Analyse unit operations, processes and design in wastewater treatment.

C. Apply the appropriate models and methods for the process design, calculation and analysis of unit.

D. Assess the impacts of unit processes on the treatment systems and relevant environmental constraints and regulatory framework.
Method of teaching and learning 
Formal Lectures, Tutorial Classes & Labs
Background, Regulatory Framework and Introduction: a brief overview of the history of Wastewater Treatment and relevant EU and Chinese Directives. Types of sewerage system; characteristics of wastewater including organic and inorganic constituents; wastewater quantities and diurnal variations; treatment works capacities; biochemical oxygen demand. • Biological Oxidation and Nitrification: aerobic and anaerobic oxidation; oxidation of inorganic matter; nitrification/denitrification; phases of bacterial growth; bacterial growth in wastewater treatment processes; efficient operation of wastewater treatment systems. • Treatment Systems: Preliminary, Secondary and Natural Treatment. Unit operations and systems. Grit chamber, primary sedimentation. Biological filters, constructed wetlands, aquatic systems. • Sedimentation: applications; types of settling; sedimentation theory; sizing of sedimentation tanks; settling column analysis; efficiency assessment. • Activated Sludge Process (ASP): unit processes and systems; fundamentals; ASP kinetics; mathematical modelling; process design; determination of kinetic constants • Advanced Treatment and Sludge Management: The most common types of advanced wastewater treatment used and the contaminants removed by each. Disinfection of treated effluents. The origins of sludge and issues dealing with the disposal of sludge.
