Because a coffee filter is permeable by liquids, it releases the liquid into the carafe below. The hot water is usually dripped or poured slowly on top of the coffee grounds in the filter. As the water drains down through the grounds, it takes on the properties of the grounds and becomes brewed liquid coffee.How do cotton balls filter water?
To do filtration using cotton balls, one need to flow water through the cotton balls in a tube. When this happens, large particles which were present in the water gets tangled in the cotton fibers and fail to exit the tube. This process cannot be used to remove salt, most of the chemical impurities from water.How does Clay filter water?
