Introduction to 5-Stage Water Purification Model
This 5-stage water purification model demonstrates a basic approach to cleaning water using common materials. Each stage in the model targets different types of impurities, illustrating how a combination of filtration methods can improve water quality.
Components of the Model:
Big Rocks: The first stage uses big rocks to remove larger particles and debris from the water, such as leaves, sticks, and large sediments. This stage acts as a preliminary filter to remove coarse impurities.
Small Rocks: The second stage uses small rocks to further filter the water, capturing smaller particles and sediment that were not removed in the first stage.
Coal (Activated Carbon): The third stage employs coal or activated carbon to remove chemicals, odors, and some contaminants that affect the taste and quality of the water. This stage also helps absorb smaller impurities.
Sand: The fourth stage uses sand to filter out fine particles and sediments, providing additional purification by trapping smaller debris that passes through the previous stages.
Tissue Paper: The final stage uses tissue paper as a fine filter to catch any remaining particles and impurities, ensuring that the water is as clean as possible by the end of the process.
This working model demonstrates the purification process through five distinct stages, each utilizing different materials to filter and clean the water. Contaminated water will pass through each stage, starting with the big rocks and progressing through small rocks, coal, sand, and finally tissue paper. The model will visually show how each material contributes to improving the water quality.
