Sea animals like zooplankton are so small you can see them only with a microscope. Big fish swim through these waters too, such as great white sharks, manta rays, and ocean sunfish. The largest animal ever to live on Earth is an ocean mammal called the blue whale. It’s as long as two school buses! Dolphins, porpoises, and sea lions are also ocean-dwelling mammals. TheSand Filter - an overview | ScienceDirect Topics,The homogeneous sand filter has a 0.9–1 m deep bed of typically 0.85–1.7 mm sand (d 10 =0.9 mm) placed on a 50 mm layer of 4–8 mm or 75 mm of 6.7–13.2 mm gravel. Homogeneous sand of effective size up to 1.3 mm has also been used. The stated size ranges for sand and gravel are generally 5 and 95 percentiles.How does sand form? - National Ocean Service,Sand forms when rocks break down from weathering and eroding over thousands and even millions of years.

No single media specification (size and depth) can be applied universally for all waters; the choice depends on the water quality and upstream processes, filtered water quality objectives, cleaning method, filtration rate and length of filter runs.
