Generally filtering drinking water involves removing smaller and smaller particles in succession. The first stage is to remove large debris by a coarse screen, the smaller heavier sediments are allowed to fall out in a settling area or pond, the water id then passed though a filter medium (either a fabric or aggregate bed of sand and other solids. This leaves only colloidal material in the water. The colloids are precipitated out with an agent like aluminum hydroxide then filtered out in a secondary filter medium. Dissolved organic may be removed by passing the particulate free water through an activated carbon bed.

There are lots of different methods. Some methods entail water passing through a filter, like sand. Others filter out impurities through chemical processes. Check out this site for a great explanation: http://en.wikipedia.org/wiki/Water_purification
Tsunami do not have steps, they are a water wave.
The steps of water cycle include:EVaporation of waterCondensationPrecipitationThe water is recycled using this method.
sequence the steps taken from water vapor to sleet?
What are the steps in the water cycle and what happens at each step
the water cycle have 3 main steps but there is really 7 steps. evaporation, condensation, accumulation, ground water, run off, transiration.
