Module overview

The module covers two main themes. One looks at the types of process that are used to purify water to a standard acceptable for distribution. The subject material is taught so as to give a fundamental understanding of the physical, chemical and biological mechanisms involved in these operations. These include: coagulation and precipitation, sedimentation, filtration and disinfection. Water quality standards relevant to water use are briefly reviewed, along with the rationale for the adoption of such standards from the perspective of protection of public health.

The other part of the module looks at the sources and types of wastewater that are generated by an industrialised society, with a focus on urban wastewaters. These are considered from the viewpoint of how treatment is carried out so as to prevent environmental damage upon discharge. The taught element of the course covers the various unit operations concerned with the preliminary, primary and secondary treatment of municipal wastewaters: treatment of industrial wastewaters is also briefly mentioned as similar technologies are used, and any differences from municipal wastewater are highlighted. The treatment of the biosolids generated as a result of wastewater treatment is critically analysed in relation to the final disposal options.
