'''Water purification''' is the removal of contaminants from untreated water to produce drinking water that is [[purity|pure]] enough for human consumption. Substances that are removed during the process of '''drinking water treatment''' include [[bacteria]], [[algae]], [[virus]]es, [[fungi]], and man-made chemical [[pollutants]]. Many contaminants, such as man-made chemicals and heavy metals, can be dangerous—but depending on the quality standards, others are removed to improve the water's smell, taste, and appearance. There really is no such thing as pure water. As the universal solvent the moment that purified water is exposed to the environment it interacts, even with Carbon Dioxide in the air. Water purification therefore is a process describing the treatments employed to meet the objectives of the user. To learn more about 'pure water' visit www.cleanairpurewater.com. |

{{main|sewage treatment}} |

'''Sewage treatment''' is the process that removes the majority of the contaminants from waste-water or [[sewage]] and produces both a liquid effluent suitable for disposal to the natural environment and a [[sludge]]. To be effective, sewage must be conveyed to a treatment plant by appropriate [[Sewage collection and disposal|pipes and infrastructure]] and the process itself must be subject to [[Sewage - regulation and administration|regulation and controls]]. Other wastewaters require often different and sometimes specialised treatment methods. At the simplest level treatment of sewage and most wastewaters is through separation of solids from liquids, usually by settlement. By progressively converting dissolved material into solid , usually a biological floc and settling this out, an effluent stream of increasing purity is produced. |
