Requisites
Pre-requisite: ENV4203 and ENV2105 or Students must be enrolled in one of the following Programs: PDEV or GCEN or METC or MEPR or GCNS or GDNS or MENS
Overview
The effective treatment of water and disposal of liquid wastes is the responsibility of the local authority engineers in many communities. The primary responsibility in any waste treatment system is to ensure that community health is not endangered, but increasing concern is also being shown that the environment should not be unnecessarily harmed, and that the systems employed are cost effective.
This course revises and builds upon the principles of water and wastewater treatment introduced in ENV4203 Public Health Engineering course. The course aims to develop a higher level of expertise, principally in the areas of water and wastewater treatment methodology, and the design of water and wastewater treatment facilities.
Course learning outcomes
On completion of this course, students should be able to:
- Justify the physical and chemical processes involved in the treatment of surface water including detailed theories of sedimentation
- Design a typical water treatment system for a small community
- Describe wastewater characterisation
- Analyse the principles and biological processes involved in advanced biological wastewater treatment of a typical urban wastewater having organic and nutrient contaminants
- Design the components of wastewater treatment systems tailored to cater for different wastewater compositions
- Evaluate the options available for disposal of treated wastewater and sludge
