FILTRATION

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

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
