Drinking Water
Drinking water is provided through water purification plant. The source of water is river, lake or reservoir treated by sand filtration. Sand purification removes particulate matters such as suspended sludge and bacteria to make it for drinking. At large scale water purification plant is by sand filter bed and small and medium scale purification plant is by sand filtration tank. Sand Filtration proceeds filtration and periodical backwashing (e.g. 1 time/day)over and over. In case of the water is dissolving high color matters or irons, additional treatment process or facility may be required combine with sand filtration, but sand filtration helps to improve treatment effects and reduce burden on the other systems.
