Electrolytic Defluoridation process is a water purification system suitable for fluoride affected area with water containing excess fluoride. In areas having a power crisis, a system running on solar energy can be incorporated.
The process is effective to remove excess fluoride and also bring down the bacterial load of the raw water.
The Defluoridation process is based on the principle of electrolysis using aluminum plate electrodes placed in the raw water containing excess fluoride. During the electrolysis, anode gets ionized and fluoride is removed by complex formation, adsorption, precipitation, coagulation and settling.
Advantages:
Developed by NEERI, India's premier research Institute
Reduces the fluoride concentration to < 1.0mg/l
Useful for safe water supply in fluoride affected area
Easy to operate even by unskilled persons
Minimum maintenance
Produce potable water with palatable taste
Quantity of sludge produced is much less (60- 70%) as compared to conventional treatment methods
Simultaneous reduction in bacterial contamination in treated water.
