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
Organic, hydraulic and surface
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
