This course provides an introduction to some of the more common concepts in measurement and calculation in Wastewater Treatment. Units, and the use of units, in measurements are explored together with a discussion of accuracy and precision in relation to measurement errors. We explore the interrelationship between loadings, flows and concentrations with a focus on understanding the terminology, conversions and getting the units right. We’ll also cover basic water chemistry, using this to describe aspects of both drinking water treatment and wastewater treatment.
There are lots of examples and opportunities for you to practice your skill in mathematical manipulations as we attempt to find solutions to typical calculation examples. Grappling with maths isn’t everyone’s idea of fun but, in this unit, the aim is to make ‘having a go’ as interesting, informative and painless as possible. If you want to find out more about the numbers underpinning wastewater treatment processes then this is for you.
The focus of this course is on a general description and overview that demonstrates the way in which the different aspects of a water business link together to deliver their services and products. The technical content of this course is limited to only that which is required to appreciate the nature of the various water treatment or pollution removal processes.
By the end of this module you will have obtained knowledge of:
A basic understanding of the terms and formulae used when discussing simple water chemistry and sanitary analysis, together with an understanding of the concepts of concentration, flow and loading Interpret the terms population equivalent, hydraulic loading and organic loading, and understand the implications of the numerical values associated with key parameters contained within discharge consents to surface waters Appreciate the ways in which hydraulic, surface and organic loadings can be used to describe the treatment of wastewater by various physical and biological processes. 
Delivered via the CIWEM Learning Platform, the course is self paced e-learning with tutor support available on the course discussion forum throughout. Study at your own pace and access support when you require it. There are two live Q&A sessions incorporated into the course.
This module has a learning time equivalent to 2 – 3 hours per week for 5 weeks. You will have ten weeks to complete the course including approximately five weeks to read through course content and five more weeks to complete their final assignment. In total you will have four months access to the Online Course portal. Please note this is a guideline and learning times will vary person to person.
