subject: On Water Purification [print this page] The process of water purification is a compound procedure. The water must undergo intensive process of cleansing before it is made ready for use. The procedure removed biological contaminants, chemicals and other materials from water. Note that there are contless ways that a water may be contaminated, but, there are also ways to purify it.
Generally, the procedure includes the use of filtration systems to filter and clean water. Our environment has it natural purification procedure - waters are filtered by the roots, soil, and stones on the ground. However, with the number of manmade contaminants that add to the undesirable state of ground water, extra means must be employed in order to clean water for human consumption.

Purifiers can also be larger appliances, similar to a water softener, and capable of filtering water for the entire home through a single, larger unit.
There are many type of methods on how to purify and cleanse water. Physical processes include filtration and sedimentation, but biological processes can also be quite common, including activated sludge filtration and the use of slow sand filters. There is also a process that uses chemicals that involves chlorination and flocculation. Advance methods of water purification applies ultraviolet light and electromagnetic radiation.
