Water reuse: calculating energy demand in membrane technology
When water is scarce − as is the case in many arid regions of the world − the only available options for water supply are seawater desalination and wastewater reuse. Both of these make extensive use of membrane technologies, and both have key design and operating parameters which define their performance and, ultimately, their cost. So what are the energy implications for using these technologies?
This four-hour course is directed at undergraduates with an interest in water reuse but who have no direct experience of the water industry. Learners are not expected to have any engineering knowledge but must be ready to perform calculations to work through the videos and mathematical equations in this course.
Learners start by looking at the fundamental relationships governing flow and pressure in water systems, building to a complete determination of energy consumption for both process options. By the end of the course, learners will have a basic understanding of membrane processes and will appreciate the importance of energy consumption of membrane technologies for seawater desalination and wastewater reuse.
