Subject Specific Practical Skills

Having successfully completed this module you will be able to:

• Prepare an outline flow sheet and process design for a conventional water or wastewater treatment plant (contributes to AHEP D4)

WATER TREATMENT:

1. Overview of water resources and water supply

2. Water quality standards

3. Raw water characteristics and quality criteria

4. Conventional water treatment methods including:

• Physical - screening, filtration, settlement
• Chemical - coagulation, disinfection
• Water treatment process selection and design
• Maintenance of water quality in distribution
• Emerging options and applications e.g. desalination

WASTEWATER TREATMENT:

1. Introduction to wastewater collection, handling and disposal systems

2. Classification and types of wastewater

3. The concept of unit operations for wastewater treatment

4. Basic process flow sheeting

• Preliminary and primary treatment operations
• Secondary treatment including biological processes

5. Wastewater treatment plant design and process selection

Teaching and learning methods

The main teaching and learning methods are lectures and problem-solving coursework supported by tutorial sessions. Basic flowsheeting exercises are also included.

The lecture course introduces the basic unit processes that are used in the treatment of water and wastewater, the standards applied, and the issues associated with residuals management. Because of the nature of the course, reading and viewing of additional material is recommended, associated both with the general aspects of the course and to back up individual lectures. A number of web-based resources in the form of presentations and additional reading materials are provided to help reinforce the basic material covered in the lecture course.

Assessment strategy

Coursework Assessment - on water and wastewater treatment plant including numerical problems.

Referral Method - Open book examination: i.e. a set of questions completed over a specified period (normally 3 weeks) during the summer vacation, during which time the candidates are allowed access to lecture notes and other reference materials.

The examination paper is sent to candidates by email and posted on Blackboard. The completed script must be submitted by a specified date through the coursework system. The questions resemble typical questions from previous examination papers, but the candidate is required to attempt all of them.

Summative

This is how we’ll formally assess what you have learned in this module.

Referral

This is how we’ll assess you if you don’t meet the criteria to pass this module.

Repeat

An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
