Calculations

Calculations

This unit provides an introduction to the chemical principles underpinning water treatment and the basic mathematical manipulations associated with loadings and concentrations. 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 mathematical gymnastics until we find answers to examples that we can both agree on. 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 water treatment processes then this is for you.

Key points covered in the unit include:

• An explanation of terms such as pH, acidity, alkalinity, moles and molarity, temporary and permanent water hardness, mass per unit volume, BOD, COD etc.
• Units and the interconversion between concentrations of pollutants in water and solids, flows of liquids and loadings at sewage treatment works, in rivers and on land
• Organic, hydraulic and surface loadings
• Population equivalent
• Compliance and 95 percentiles

Note: The content of this unit relates to aspects of both drinking water and wastewater treatment and there is inevitably some overlap with material contained within both the municipal wastewater treatment and the potable water treatment units.
