Watermaths presents the mathematics underpinning the design and operation of the individual unit process technologies used for purifying water and wastewater. The book aims to provide sufficient information to enable you to tackle the most important calculations in this area, without requiring any prior knowledge of the subject and assuming only a very basic grounding in science or engineering.
This book focuses on the most essential areas of knowledge required, containing tuition in basic numeracy as well as the chemistry, process engineering and fluid physics of water and wastewater treatment technology. The simple and succinct delivery is designed to get you up to speed as rapidly as possible: you are given sufficient background information to explain the purpose of the calculations, and ultimately tackle the complete wastewater reclamation plant design problem at the end. Each chapter contains example calculations, followed by exercises intended to reinforce the learning (for which solutions are given). Exercises range in difficulty from simple single calculational-step problems to more complex ones, and the over-arching design problem provides some context to the mathematics.
The third edition is extended to include cost analysis – calculation of net present value from capital and operating expenditure with discounting – and the determination of key biological process parameters. There are also additional exercises included in most chapters, along with representative drawings of the key unit processes as used in process and instrumentation diagrams.
Watermaths is designed to be understood by those relatively new to the water sector and is intended as a primer rather than a comprehensive handbook. At the same time, it is sufficiently comprehensive to permit design calculations for most water and wastewater treatment unit processes.
