Final answer:
Different types of filter media used in water filtration systems include sand, gravel, anthracite, activated carbon, and zeolite.
Step-by-step explanation:
In water filtration systems, different types of filter media are used to remove solids from the water. One type of filter media is a conventional gravity filter that consists of sand, gravel, and anthracite. These filter materials have different sizes and densities, allowing them to trap particles of varying sizes. Another type of filter media is activated carbon, which is used to remove undesirable taste and odor from drinking water. Zeolite is also used as a filter media due to its ability to remove certain metal ions from water.
