TO CONFISCATE FLUORIDE FROM GROUNDWATER

Journal Name:

Publication Year:

Abstract (2. Language): 
Presence of fluorides in drinking water has become a public health problem. The adverse effects have increased the need to defluoridate water. Several methods like adsorption, coagulation, membrane processes and electrochemical techniques have been studied for defluoridation of water. However, the generation of large volumes of sludge, hazardous waste categorization of metal hydroxides, and high costs associated with chemical treatments have made them less acceptable. Membrane processes are effective, but they increase the operational cost and also remove the beneficial contents of water. Researchers have investigated the influence of various parameters like solution pH, current density, flow rate, residual aluminium, and operational cost on the process of electrocoagulation (EC). Experimental results also suggest that using a multi stage treatment over single stage treatment would be a better option as it increases the defluoridation efficiency and reduces the energy requirements. Identifying the potential of this process can make it the distinct economical and environmental choice for defluoridation of water.
