0.0 stars

Students experience firsthand one of the most common water treatment types in the industry today, flocculants. They learn how the amount of suspended solids in water is measured using the basic properties of matter and light. In addition, they learn about the types of solids that can be found in water and the reasons that some are easier to remove than others. Encompassing the concepts of force and motion, attraction and repulsion of charged particles, and properties of matter, during the associated activity students see scientific concepts they already understand through the eyes of engineers who apply them to the removal of solids from water via chemical flocculants.

Prior to reaching households, water is exposed to a variety of treatments designed to render it fit for human consumption and use. One of the first treatment steps is the removal of suspended solids using chemical additives called flocculants. In this activity, students learn about two commonly used flocculants and clean water collected from a local pond or river. They experiment with flocculant, stirring and pH variables.
