  • 摘要:The Government of Rajasthan has started Rajasthan Integrated Fluoride Mitigation Programme (RIFMP),to provide fluoride free water in fluorosis endemic areas of the state. In the present study, communitylevel defluoridation plants are investigated with regard to their defluoridation potential and determinationof residual aluminium concentration in treated water at Nagaur and Jodhpur districts in Rajasthan,India. A total of 38 groundwater samples were collected from various community level Bio-Filter® mediabased defluoridation plants in fluoride rich villages of the study area. The fluoride concentration in rawwater ranged from 0.9 to 3.61 mg/L in Nagaur and 1.18 to 2.54 mg/L in Jodhpur. The removal efficiencyof plants operated in Nagaur lied between 88 to 100% except at Chapri Kallan II site (46%). On theother hand, the removal efficiency of plants operated in Jodhpur ranged from 97 to 100%, except atJujanda (59%). The presence of residual aluminium in treated water was found to be in traceconcentrations. The statistical analysis shows that fluoride uptake capacity has a strong correlationwith fluoride concentration and alkalinity of raw water.
