Sedimentation produces partially clear water | Solutions | Chemistry

This video discusses one of the easiest and well known methods of purifying water. First we let muddy water remain undisturbed for a few hours. The large particles settle down due to gravity but the water still has many small particles suspended in it. Carefully, without disturbing the bottom layer, pour some of this muddy water in to another beaker, This process is called decantation. This water is not yet fit for consumption, though since it has finer particles that are visibly suspended in it, but are too small to separate through sedimentation.
