Waste Water Treatment Lab
Abstract:
Introduction:
Write an introduction in paragraph form that answers the following questions.
1. Why do we have a shortage of clean water in the US?
2. How do we use water? (off stream use vs. in stream use)
3. What is water pollution?
4. How did the Hudson River Case Study (Pg. 399) exemplify water pollution and remediation
(clean up) efforts?
5. What is Biochemical oxygen?
6. What are water borne diseases?
7. What is surface water pollution?
8. What is ground water pollution?
9. How does a septic tank work?
10. How do waste water treatment plants work?
11. What is primary and secondary treatment?
12. What is Chlorine treatment?
13. What are the US policies on water pollution and environmental law?
Materials:
You must come up with the materials you will use to purify your water. Suggestions: plastic water
bottles, 2 liter soda bottles, gravel, sand, coffee filters, tissue paper, pieces of cloth, plants.
Material
Person bringing it
Procedure:
1.
Do background research using the materials that Ms. Hobson gave you and your notes to
familiarize yourself with different methods of remediation of waste water (such as sewage).

Work with your group to determine a mechanism to filter or purify 200 mL of waste water
(of unknown substance…yet ) that you can bring in to class/create in class using materials
that you brought in.
You will have 50 minutes in class to build your water purification treatment. Plan
accordingly.
Develop a procedure for Wednesday or Thursday. Write it below.
Come prepared (Wednesday or Thursday) with all your materials and ready to work.
Complete your water purifier.
Ask Ms. Hobson for the “waste water”.
Take 5 mL samples of the waste water initially for dissolved oxygen, pH, Nitrogen and
Phosphorus.
Slowly (in 50 mL parts) pour the waste water through your treatment system, until you
reach 200 mL.
Let your purifying device sit for one week.
Take 5 mL samples of the purified water for dissolved oxygen, pH, Nitrogen and Phosphorus.
Add your fish.
Create your conclusion.
