how to make wastewater purification working model for a science project with a 5-stage water purification

by

Creating a wastewater purification working model for a science project with a 5-stage water purification process can be both educational and fun.

Here’s how you can do it using cardboard, paper cups, and other materials:

Materials Needed:

  1. Cardboard (for factory structure)
  2. Plastic tray (for waste water depiction)
  3. Paper cups (6 or more)
  4. Big gravel, small gravel, coal, sand, tissue paper (for purification process)
  5. Plastic containers (for purified and waste water)
  6. DC water pump
  7. Plastic tubing
  8. Scissors
  9. Glue or adhesive
  10. Markers or paints
  11. Water (for testing)

Step by Step Video Instructions:

  1. Prepare the Factory Structure:
    • Use cardboard to create the structure of the factory. You can make it look like a building with several floors or sections.
    • Use markers or paints to add details such as windows, doors, and signs indicating different areas of the factory.
  2. Create the Waste Water Depiction:
    • Place the plastic tray outside the factory structure to represent the waste water generated by the factory.
    • You can simulate pollutants in the waste water.
  3. Set Up the 5-Stage Water Purification Plant:
    • Arrange five paper cups in a row steps to represent the stages of water purification.
    • Label each cup accordingly: “Big Gravel,” “Small Gravel,” “Coal,” “Sand,” and “Tissue Paper.”
    • Fill each cup with the respective filtering material: big gravel in the first cup, small gravel in the second cup, coal in the third cup, sand in the fourth cup, and tissue paper in the fifth cup.
  4. Connect the Purification Process:
    • Use plastic tubing to connect the bottom of each paper cup to the top of the next cup in line.
    • Ensure that the tubing allows water to flow from one stage to the next.
  5. Set Up the Water Pump and Containers:
    • Place a plastic container at the end of the fifth cup to collect the purified water.
    • Place another plastic container at the bottom of the first cup to collect the waste water.
    • Connect the DC water pump to the waste water container using plastic tubing. The pump should be submerged in the waste water.
  6. Test the Model:
    • Pour water (representing waste water) into the plastic tray to simulate the waste water generated by the factory.
    • Turn on the water pump to start the purification process.
    • Observe how the water flows through each stage of purification, filtering out impurities.
    • Collect the purified water in the container at the end of the fifth cup.
  7. Demonstrate and Explain:
    • Use the model to explain each stage of the purification process, highlighting how each filtering material removes different types of pollutants.
    • Discuss the importance of wastewater treatment in protecting the environment and public health.

This working model provides a visual representation of wastewater purification and can help demonstrate the process of treating wastewater for reuse or safe disposal.
