Introduction
This webquest is about the processing of wastewater, also known as wastewater treatment.
This webquest will help you to understand how this process works, where our used water goes and also will give you knowledge in chemestry class.
Webquest is based on information from https://www.youtube.com/watch?v=ZSFdOjxB-1I and online information sources which you will see in following pages.
This webquest is for students.
