The presence of fluoride in higher concentration is probably the most common problem faced by the consumers and water treatment professionals. It may cause dental fluorosis. Hence to remove fluoride from water among the methods available, adsorption has gained popularity due to several advantages. A batch study adsorption has been conducted by adsorption process using activated carbon prepared from Bale fruit (Limonia acidissima) shell as adsorbent and the removal efficiency is determined by optimizing the parameters such as dosage, time, pH and concentration. The maximum removal efficiency was found to be more than 63 %. This experimental study proves to be an economical method of fluoride removal since the developed product is a waste product. Even small industries, with fluoride bound wastewater can adopt this method of treatment and hence prevent the polluted water entering the stream.
