About Jar Test
Jar Tests are used in the water treatment process to determine the necessary amount of coagulant. The jar test uses an apparatus that aids in the mixing, flocculation, and settling cycles. Multiple jars are used, all having various amounts of the coagulant, while being mixed at the same speed. One of the main takeaways from the Jar Test is that students will learn how to create a graph using multiple data points, and then analyze the chart to determine the optimal coagulant dosage.
This experiment can be adapted for middle school students.
