WATR06014 2018 Introduction to Drinking Water Treatment

Define and describe water quality parameters, parametric values and methods of assessment and consumer expectations.

Describe disinfection processes, distinguish between drinking water treatments processes and identify DWTP plant performance, how determine performance, critical control points, safe and secure water.

Identify and describe the "risk" and "barrier" approach to achieving safe drinking water and the main contaminants of water and their sources.

Understand  Log Credit and Log Removal approach to Water Treatment, describe drinking water monitoring requirements and carry out lab testing.

Describe preventative measures and remediation works for loss/wastage of treated water

This module will be delivered using blended learning techniques. This will include online lectures (via adobe connect or similar), workshops and site visits augmented by independent learning and directed learning. This approach is expected to address student-learning needs. A learning platform such as Moodle will be used to upload educational material (i.e. presentations and recordings of online lectures plus supplementary reading material) and as a means of assessment (e.g. quizzes, uploading assignments and journals). This blended approach (lectures and workshops) brings students together to facilitate group
learning.

This module is 40% continuous assessment and 60% final exam.

Repeat Continuous Assessment and/or Final Exam.
