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, community level defluoridation plants are investigated with regard to their defluoridation potential and determination of 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® media based defluoridation plants in fluoride rich villages of the study area. The fluoride concentration in raw water ranged from 0.9 to 3.61 mg/L in Nagaur and 1.18 to 2.54 mg/L in Jodhpur. The removal efficiency of plants operated in Nagaur lied between 88 to 100% except at Chapri Kallan II site (46%). On the other hand, the removal efficiency of plants operated in Jodhpur ranged from 97 to 100%, except at Jujanda (59%). The presence of residual aluminium in treated water was found to be in trace concentrations. The statistical analysis shows that fluoride uptake capacity has a strong correlation with fluoride concentration and alkalinity of raw water.

Abstract


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, community level defluoridation plants are investigated with regard to their defluoridation potential and determination of 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® media based defluoridation plants in fluoride rich villages of the study area. The fluoride concentration in raw water ranged from 0.9 to 3.61 mg/L in Nagaur and 1.18 to 2.54 mg/L in Jodhpur. The removal efficiency of plants operated in Nagaur lied between 88 to 100% except at Chapri Kallan II site (46%). On the other hand, the removal efficiency of plants operated in Jodhpur ranged from 97 to 100%, except at Jujanda (59%). The presence of residual aluminium in treated water was found to be in trace concentrations. The statistical analysis shows that fluoride uptake capacity has a strong correlation with fluoride concentration and alkalinity of raw water.
