DEFLUORIDATION PLANT (SOLAR/ELECTRIC)
NEERI has developed the plant which run on solar energy / electrical energy & is based on electrolytic process for removal of Fluoride from Ground Water. The process is free from chemical. The basic principle of process is adsorption of fluoride with freshly precipitated aluminum hydroxide which is generated by the anodic dissolution of aluminum in an electrochemical cell.
Electricity is the main raw material & hence where ever electricity is not available a suitable solar panel can be installed. The anode is continuously consumed & needs to be replenished.
