Abstract

In recent years there has been extensive use of RO systems for water purification. Aim: To study the effectiveness of 3 commercially available RO systems in removing fluoride from water. Methodology: An observational study was undertaken, fluoridated water samples were prepared. After purification pH, TDS and fluoride concentration were analyzed. The same procedure was repeated after 1 week. Results: All RO systems showed no statistically significant difference in mean pH values. Kent RO system reduced TDS level at all water fluoride concentrations. Conclusion: All the RO systems were able to bring back the fluoride levels to the optimal range.
