A water filter is part of a physical device built for filtering and purifying water of impurities. Water filters cleanse water for drinking. But there are cases in which the intent of chemical process of filtering water goes beyond filtering for drinking. Water may also be filtered for irrigation, aquariums and swimming pools.
There are three types of filters. These are the Water treatment plant filters, Point-of-use filters, and portable water filters. Water treatment filters may include media filters, screen filters, disk filters, slow sand filter beds, rapid sand filters, and cloth filters.
The Point-of-use filters are more commonly used at home and may include the granular activated carbon filters or GAC for carbon filtering, microporous ceramic filters, and metallic alloy filters. Also included are carbon block resin or CBR and ultrafiltration membranes. There is a water filter that uses several filtration methods like the multi-barrier system.
The Portable water filters are exclusively used for portable water purification.
In water treatment filters, the slow sand filtration system consists of a housing, water layer, filter bed, drainage system, and flow control.
