ENVIRONMENTAL CHEMISTRY: WATER TREATMENT AND FILTRATION

Students will develop a knowledge of the processes performed at a water treatment plant and understand the reasons for each process.

• They will perform, on a small-scale, several of the procedures that occur in a water treatment plant on “polluted” water.
• They will examine the changes in the water after each treatment step is performed.
• They will also observe physical characteristics of water, such as clarity, color, odor, and how they are affected from the beginning of the treatment process until the end.
• Kit contains enough materials for 15 groups of students.
• Teacher's Manual and Student Study Guide copymasters are included.
