Watermaths is all about the use of maths in water and wastewater technology design and operation. The second edition is designed to give you the knowledge you need to master the basic maths required for designing and running water and wastewater treatment processes.

Suitable for students of undergraduate water engineering, civil engineering or environmental science courses, the book is also ideal for practitioners in the water industry who need a basic refresher.

Watermaths is designed for self-paced study or distance learning. A brief explanation of each topic is followed by examples and exercises designed to reinforce learning.

Most of the fundamental unit operations are covered – from flows and pressures in pipes and across filters to transfer of oxygen from air into water, from the dosing of chemicals to the configuration of chemical or biochemical reactors, and from single unit processes to a complete water reuse scheme, covering the following core disciplines:

  •     manipulation of equations, including logarithmic and exponential expressions
  •     fluid physics for describing flow through pipes, channels and filters
  •     chemical concentrations and reactions for defining chemical dosing
  •     chemical and biochemical kinetics for assessing the impact of speed of reactions
  •     mass balance for determining fate of materials through unit processes
  •     mass transfer for determining transfer of materials across boundaries within processes
  •     reactor theory for designing biochemical and chemical reaction vessels.

You will understand how and where to apply each equation in tackling the most important calculations for design and operation of key process technologies. Little or no prior knowledge of the subject is required, and you need only a basic grounding in science or engineering. The book is strictly limited to the essentials, covering basic numeracy as well as chemistry, process engineering and fluid physics.

The purpose of calculations is explained, getting you up to speed as quickly as possible. Each chapter includes example calculations, followed by exercises so you can practice your knowledge (solutions are given). Exercises range in difficulty from simple single calculational-step problems to more complex ones, and an over-arching design problem provides wider context.

Simon Judd runs a Watermaths discussion forum on LinkedIn.com, where you are welcome to discuss with him and others any aspect of the subject.
