Key item features

Students use the wastewater apparatus as a model to observe simulations of primary, secondary, and tertiary wastewater treatment processes. Then they use the scientific method to explore a question about wastewater treatment and pollutant removal. The guided activity is composed of 3 processes that will require a total of 95 minutes and at least 2 class periods to complete.

This is a creative way to teach about sewage treatment!

This kit, once set up, is a clever way to demonstrate the stages of sewage treatment by using glucose as a substitute for organic waste and yeast as a substitute for aerobic, decomposing bacteria. You can have the students pour various things into your glucose-rich sewer water (such as cooking oil to represent crude oil, broken up leaves & soil) to represent other substances that may wash into a sewer system. The first stage of the apparatus removes the large debris, and the second part has the yeast which gradually break down the glucose over a relatively short period of time. The students measure and plot the declining glucose levels over 30 minutes.

great demo but a few glitches in instructions

This kit is a great demo of the wastewater treatment process. It could replace a field trip, but I used it after a trip to reinforce the processes. A couple of changes I made to the set up are: 1) I increased the amount of glucose, since the test paper has high readings on it, so I started with about 3000 mg/dL for my glucose concentration. 2) I do not use oil for the wastewater, as that is very hard to clean up afterwards. The kit could be improved with test papers that give more accurate readings in the 100-500 mg/dL range. You could most likely set up this kit as a series of beakers and decant material from one beaker to the next.

fun and educational

The wastewater treatment kit is extremely fun and really drives home the point. The first time I used it, I was surprised to see how interested students were in how their water was treated. The kit serves as a great introduction to the chapter on water treatment. It is appropriate for all levels of environmental science.
