The dihydroxylation process produces activated alumina from aluminum hydroxide to give a porous solid object. These are widely used as desiccants and filters for water purification. Natural drinking water contains many minerals like fluoride, arsenic, selenium, etc. These minerals are the reasons for considering water as a precious part of our diet and good health. But if any of these minerals exceed the permitted limit, it can lead to severe health issues. Thus, the purification of water is highly recommended. In this article, we will see the role of activated alumina in water treatment.

Collection of artworks in shades of blue by Nathan Altman, Arsen Kurbanov, Sergei Osipov, Mikhail Nesterov, Konstantin Gorbatov, Konstantin Grabowski, Konstantin Somov and other Russian painters. The assigning of symbolic meanings to colors is probably as old as symbolism itself. In fact, words are well adapted for description and the arousing of emotion, but for many kinds of precise thought other symbols are much better. (John B. S. Haldane)
