Educational resources

Our ever-expanding range of educational resources will provide you and your staff with useful learning material for understanding the theory and practice of using water in an efficient and sustainable manner.

Our interactive case studies will take you through realistic scenarios of water treatment; you'll learn about the issues that need to be considered when dealing with production problems due to poor quality water and how to solve them.

Designing a Water Treatment System
You will learn about a real greenhouse that has a waterborne pathogen problem, and needs your help to design a water treatment system.
