Water Quality Activity 2 Treatment Amy Biddle

Water Quality Activity 2: Objectives: To use digital imaging to track the removal of natural organic matter from water by alum and activated carbon. To compare the effectiveness of treatment methods for removing natural organic matter.

Timeline: Treatment Experiment Today: 10:00- 10:30:Water Tx Activity Intro: very short Set up: filter Break 10:45- 11:15:Finish Tx set up Allow to settle Over the course of the day (after settling) Take treatment images Thursday: 9:00- 10:00:Water treatment theory How to do image analysis: Quick Clean up aquaria and Tx dishes Friday: 9:00- 10:30:Image Analysis/ clean up: finish Group share: Results Application to classroom practice
