Fluoride Removal By A Continuous Flow Electrocoagulation Reactor From Groundwater Of Shivdaspura.

The present study focuses on the technique of defluoridation by using the process of electrocoagulation (EC). Efficacy of EC process was investigated for laboratory simulated sample called as control sample and groundwater sample collected from Shivdaspura (Rajasthan) under different operating conditions. Continuous flow experiments were conducted for fluoride removal using aluminium electrodes to study the parameters such as: current density, flow rate, number of stages in treatment, fluoride uptake capacity and residual aluminium. The results obtained showed that double stage treatment system gave higher treatment efficiency than single stage system. Residual Aluminium was measured and found in the range of 0.08-0.1 ppm which shows that EC offers better quality of water when compared with other methods of defluoridation like Activated Alumina (AA) process and Nalgonda technique.
