ENVR07042 2013 WATER and WASTEWATER TREATMENT THEORY
This module describes the nature, sources and composition of contaminants in water, municipal and industrial wastewaters as well as end products arising from treatment. The module explains how to monitor and quantify pollutants and monitor the efficiency of technologies employed and the receiving environment to ensure compliance with legislation. The module also explains the function and basic design parameters of the most commonly used processes for water treatment, wastewater treatment and residuals treatment.
Learning Outcomes
On completion of this module the learner will/should be able to;
Explain the function and design criteria of the main primary, secondary and tertiary wastewater treatment processes
Explain the function and design criteria of the main treatment processes in typical water treatment plants
Explain the function and design criteria of the main treatment processes in typical sludge treatment plants
Explain how to assess the suitability of a site for a proposed on-site wastewater treatment process
Explain how to establish appropriate management systems for the operation of various types of treatment plants
Demonstrate a knowledge of the relevant legal and regulatory frameworks dealing with water, wastewater and sludge.
Module Assessment Strategies
The module will be assessed using a combination of an end of semester final exam (60%) and continuous assessment (40%).
The first element of the continuous assessment will involve a number of short question assessments (total of 20%) to provide feedback to students on progress with their understanding of the subject.
The second element of the continuous assessment (20%) will involve a combination of individual reports on field trips to water or wasewater facilities and/or an individual or group assignment(s) requiring an in-depth review of a particular treatment process.
