By filtering sea water
Yes, clams and oysters are alive. They are muscles (bivalves). bivalves are a type of marine animal with a shell on both sides. They bury themselves in the sand in the ocean and eat plankton. Oysters can get very big, clams don't get to be as big.
Filter feeder get their food by straining (filtering) it from water, most often sea water. Examples of filter feeders are: sponges, clams, oysters, barnacles, basking sharks, whale sharks...
Oysters are mollusks that live in saltwater habitats, often found in clusters called oyster beds. They have a hard shell that protects their soft body and can vary in size and shape depending on the species. Oysters are filter feeders, meaning they extract nutrients from water by filtering microscopic algae and particles.

Oysters eat phyto and zooplankton, these are tiny plants and tiny animals that are always present in the worlds oceans.They are filter feeding mollusks, and as such capture their tiny meals with filaments extended in the water like very fine fingers.
Oysters live in the water, and thus have an abundance of water. They die if they dry up, but can conserve water by closing their shells.
Water!
Oysters thrive in the tidal zones of sea or ocean water. There are intertidal and subtidal types of oysters, which both provide a habitable place for smaller sea animals to live within their hard shells.
Filtering is a process that removes particles from a liquid. Filtering also cannot add anything to a liquid. Seeing as muddy water is water with dirt in it, filtering is not a process that can make muddy water.
