All the modules in the following list need to be taken as part of this course.
Science and Engineering Principles in Water and Wastewater Treatment
Module Leader
Dr Marc Pidou
Aim
As the first module of the Water and Wastewater Engineering MSc, this module will provide you with a base of knowledge on which the subsequent modules will build. By broadly covering the water industry, conventional unit operations employed and the basic scientific and engineering principles - all essential knowledge for water and wastewater engineers. More specifically, as part of this module, you will first acquire knowledge of the water industry, its structure and processes, relevant regulations and applicable process economics. Subsequently, you will acquire general knowledge and understanding of the conventional water and wastewater treatment processes used in the industry, which will then all be covered in greater details in the following modules. Finally, you will learn about the basic scientific and engineering principles on which these treatment processes are based including water chemistry, hydraulics and pumping, mass balance, mass and heat transfers, reactor theory, chemical and biochemical kinetics.
This module is 30 credits.
Syllabus
Classification, significance and concentration ranges of impurities in water and wastewater, including: suspended and dissolved solids, organic and inorganic compounds, trace contaminants and pathogens.
Physical methods for removing particulates, including screening and grit removal, sedimentation and filtration.
Chemical dosing, including precipitation; coagulation and flocculation processes (including basic concepts from colloid science); disinfection and chemical oxidation.
Adsorption and ion exchange.
Biological processes for wastewater treatment, both aerobic and anaerobic, including activated sludge, trickling filters and sludge digestion.
Process control systems and strategies.
Process economics and optioneering.
Water sector structure and legislation.
Aqueous chemistry: moles and equivalents, solubility, the behaviour of acids and bases and the concept of pH, kinetics and equilibria.
