Student is pouring a water and mud mixture into a glass funnel with a filter paper. Heavier elements in the mud have already settled in the beaker. The remaining sediment is in suspension in the water but can be removed by filtering through a fine paper filter. Although the water is clear after filtering the paper filter does not remove anything, like chemicals or microbes, that is too fine to be filtered by this method. | |
