ENG06037 2019 Water Treatment 201

Operate lab equipment for evaluating and testing waters for various parameters as defined by relevant directives/regulations/legislation.

Describe and carry out basic design calculations for treatment processes as part of a water treatment works.

Compile and report on the use of various scientific instruments and monitoring equipment for monitoring of water quality

Identify and describe computer control systems as used in a water treatment works.

Identify and describe the main contaminants of water and their sources.

This module will be delivered using a combination of live lectures and blended learning techniques. This will be 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. tutorial recordings plus supplementary reading material) and as a means of assessment (e.g. uploading assignments and projects). This blended approach (lectures and pre-recorded tutorials) allows students work at their own pace.

Practical Assessment:

Written lab reports.

Continuous Assessment:

mid term assessment.

Final Exam.

Written exam.

Repeat practical assignments for Autumn exam boards and final exam in Autumn repeat exam session.

1. Standards and regulations required by national, EU and WHO legislation for drinking and other water supplies.
