SELECTION OF COAGULANTS FOR CONTROLLING FLUORIDE IN WATER SAMPLES OF NALGONDA DISTRICT-TELANGANA INDIA
Abstract
The present study investigates the coagulation of fluoride by using natural coagulants such as Coccinia grandis, Abelmoschus esculant, Hibiscus rosa-sinensis and Murraya Koenigii (or) Bergera Koenigii. The physico chemical characterization of water samples collected from districts of Nalgonda was carried out in the month of (December - February) 2013. It is found that the water samples of Nalgonda district have high fluoride content than the WHO standards. Water scarcity and water quality are major problems of Nalgonda district. In this context, present study investigates for low bio based technology for removal of fluoride from ground water sources. The results revealed that percentage removal is 60-65% for both coagulants. It is found that gum of Abelmoschus esculant is efficient for removal of fluoride.
