Types of Water Filters
If you’re like everyone else in the world, you drink water. If you’re like most of the people in the world, you like your water clean, fresh, and good tasting. For this to happen, especially in the less refined areas of the world, a filter is necessary. Multiple types of filters are available for you to use to purify and make your water as tasty as possible.
Water treatment plant filters – out of the realm of home use, these filters are for mass consumption so they can be used in masse for public consumption. Micro-versions of these filters include media, screen, disk, slow sand filter beds, rapid sand and cloth.
Point-of-use filters – Filters for use in the home, also described as Granular Actived Carbon Filters, or GAC. Can be used for carbo filtering, microporous ceramic filters, ultra-filtration, carbon block resin, and metallic alloy filters. Sometimes filters use more than one method of filtration, like the multi-barrier system. Kettles have built-in filters, and jug filters can be used in small does.
Homemade water filters – For the more technologically adept, filters can be created on-site from assorted materials such as sand, charcoal, or grass. Typically created by soldiers or outdoorsmen. This is also a typical process use by the poor who do not have access to high quality filters or good drinking water. However, these filters are of the lowest quality and often do little to prevent bacteria and other pathogens from hurting the body.
Portable water filters – Generally used by aid organizations, the military, and hikers. Tend to be portable and extremely light. Water is filtered by using a hand pump, although a small few will use a drip system to force water through. Dirty water is siphoned through into a tube into a specialized filter, ending up in a container. Portable water filters can remove bacteria and protozoa that cause a flare up of disease.
