Water Treatment Basics
Water found in natural sources often contains impurities, chemicals, and living organisms and is treated to remove them using several methods, (often in combination) to make the water safe for human consumption. This paper attempts to describe (at a very high level) some of the more common issues concerning water treatment. Specific attention is paid to water filtration which is an important subset of water treatment methods.
Sediments: Sediments are simply solid particles. When they are suspended in water they affect the clarity of the water and this is called turbidity. Typically when sedimentation is discussed it is considered to be inert and harmless, like sand (although that may not be the case).
A common pre-filtering technique used for larger particulates is simply to keep the water as still as possible and let gravity do its thing. Once the larger particles have settled to the bottom, the water at the top is taken out and fed into a filter system.
Filters improve water clarity by removing the remaining solid particles....
