Module summary

Chemical engineers have a crucial role to play in the defining how every day processes that are critical to the modern world impact on the environment and also the health of society. There are perhaps no processes more important than the production of drinking water and maintaining of clean air standards. This module will examine both air and water systems from a society and engineering view point, as key examples of environmental and health impact.Secondly, leaders and managers of any chemical or process engineering activity, be this in the private or public sector, need to make responsible, ethical decisions that protect the safety and health of an organisation's employees, users of the organisation's products and the wider public. Operating with a strong regard for safety and health protects not only people, but also the organisation's reputation and future. There can be a substantial, positive return on investment in safety and health, for example through avoiding productivity and property losses, impact on future insurance premiums, uninsured costs, fines etc. This module provides the tools and ways of thinking needed to address safety in the context of a chemical or process engineering organisation.

Objectives

Semester 1 of this module combines water treatment and air quality environmental health aspects. The key objectives for the water treatment section are to arm students with a knowledge of all the major unit operations involved with front end water treatment for domestic drinking purposes. It also includes a general assessment of the need for treatment, and international challenges to clean water, as well as the main types of organic and inorganic contaminants present. The air quality section highlights key air quality issues around the world, and includes analysis of monitoring data, in order to assess whether objectives in the National Air Quality Strategy have been met, and solutions for tackling these issues.

The safety and health section of the module (in Semester 2) aims to equip students with the ways of thinking and tools needed to conduct chemical and process engineering activities in a fashion that is safe and does not have negative impacts on health. This section of the module therefore focuses on the intersection of technology, people and processes. The concepts covered in the module are illustrated by means of case studies.

Learning outcomes
- Insight into the key issues of water treatment, and water security;
- Understanding the main unit operations of water treatment from both a fundamental science and engineering perspective;
- Insight into key issues into the need for air quality;
- Understanding of how air quality can be monitored to assess conditions for the National Air Quality Strategy;
- Insight into key issues in safety, health and corporate social responsivity, in a chemical and process engineering context;
- The ability to identify, analyse and respond to safety and health issues for chemical and process engineering organisations;
- Familiarity with the design and implementation of safety management systems.
