Summary of Content

The students will learn the essential principles used in wastewater treatment. The students will understand the modern design processes for the treatment of wastewater. Also they will understand important issues in wastewater management and relevant environmental legislations.


Wastewater and its collection: Wastewater characteristics, planning for wastewater collection. Principles of biological treatment: Microbial growth rates, Treatment kinetics, Food to microorganisms ratio, Oxygen requirements. Aeration: Theory of aeration, Factors affecting oxygen transfer, Types of aerators. Biological Treatment Methods: Suspended and attached growth systems, activated sludge, Extended aeration. Nitrification-Denitrification systems, Trickling filters, Rotating disc systems. Waste stabilization Ponds: Types of ponds, Aerobic ponds, Anaerobic ponds and Facultative ponds. Design and Operation of treatment Plants: Plant layout and Hydraulic prfile, Pumping stations, Screening, Grit removal, Removal oil & grease, Floatation, Equalization tank, Primary treatment, Secondary treatment and Tertiary treatment

Learning Outcomes

On completion of this module the student should be able to:-demonstrate the principles of wastewater treatment. (A1,A2, A3, B1, B3, B4, C1, C3, C5)-outline the remediation technologies. .(B1,B3, B4, B5, B7)-describe the essentials of wastewater treatment system design and operation. (A1, A3, B1, B3,C1, C5)-apply their theoretical knowledge to and conduct analysis on a broad variety of wastewater management problems. (C6)-compare advances in the treatment technologies and design processes. (A1, A3, B1, B3,C1, C5)

Teaching / Learning Strategy

The main teaching method will be based on lectures with laboratory exercises used to relate theoretical concepts to practical experience. The students will be expected to carry out directed reading exercises and self-learning exercises on emerging technologies in wastewater treatment and disposal. Tutorials will be used to strengthen the module material and to discuss the issues raised by the directed reading. The design principles for various wastewater engineering systems and wastewater collection and disposal, Wastewater treatment systems and Design practice
