Slowly pour this turbid liquid into the top of the filter, allowing gravity to pull the fluid through the media layers. Testing and Analysis Procedures Prepare a sample of dirty water by mixing soil, food coloring, and grass clippings in a separate container.
Testing Different Filter Layers and Observing Purification Results
Scissors or a utility knife are required for cutting, while measuring cups ensure consistent layer thickness for reproducible results. Biological action within the sand layer creates a biofilm that consumes organic waste, enhancing the purification process.
The fine sand layer completes the filtration stack, responsible for removing microscopic particles and bacteria. Observe the transformation as the water drips into the collection vessel, noting changes in clarity and odor.
Test Different Filter Layers and Observe Water Purification Results
Physical filtration occurs when water passes through layers of gravel and sand, trapping larger particulate matter against the media’s surfaces. This process allows students to visualize the complex steps municipalities use to convert raw water into potable fluid.
