Gravitational Settling

Gravitational settling is the process where particles or heavier substances in a fluid or gas move downward under gravity's influence. In natural or industrial contexts, this means denser particles, such as sediments in water or dust in the air, gradually sink to the bottom because gravity pulls them downward. This separation allows lighter components to rise or remain suspended, aiding processes like water purification or sediment formation. Essentially, gravitational settling relies on the natural tendency of heavier materials to move downward in a gravity field, leading to separation based on density differences.
