While trace amounts of fluorine are essential for life, its excessive intake leads to a disease known as fluorosis. It is a predominant ailment in majority of the countries inclusive of India. It is caused also by drinking fluoride containing water. Retention of fluorine in bones and teeth occurs through F–(OH) exchange on their inorganic component known as hydroxylapatite. Endeavour of the present study is to design a column using activated alumina as an adsorbent for continuous defluoridation of water for domestic purpose. As a part of it, operational defluoridation capacity of alumina was determined by variation of different factors (amount of alumina, time, temperature, added salts). A family of four members was taken as a model. The initial and final fluoride concentrations were taken as 2.0 and 0.7 ppm, respectively. Dimension of the unit (adsorbent bed diameter and height) was determined.
