Sediment transport - Wikipedia Sediment transport is the movement of solid particles (), typically due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained Sediment transport occurs in natural systems where the particles are clastic rocks (sand, gravel, boulders, etc), mud, or clay; the fluid is air, water, or ice; and the force of gravity acts to move the .
FILTRATION - Environmental Protection Agency pressure filtration tended to replace slow sand filtration in new plants and, in some cases, slow sand filters were replaced by rapid gravity filters following introduction of a coagulation stage The slow sand filtration process has come back into favour in recent years due to its superior ability, compared to rapid gravity filtration, to remove
