Abstract

 Water is one of the most precious and  important resources. We must consume safe, wholesome,  and drinking water. The level of fluoride in the  groundwater varies greatly among regions in India.  Fluoride poisoning has reportedly gone out of hand and is  currently harming at least 267 districts spread over 19  states in India, according to the Ministry of Water  Resources. Thirteen districts in Andhra Pradesh have a  fluoride contamination problem in eleven of them.  According to IS 10500 - 2012, drinking water fluoride  values must be between 1.0 mg/L and 1.5 mg/L. The  Nalgonda method is one of the methods used to remove  too much fluoride from groundwater. These strategies all  have a variety of shortcomings. Adsorption techniques  have been shown to be more efficient. ResearchersDue of  their affordability and effectiveness, adsorption  techniques are more frequently used by researchers.

It has been noted that at an initial fluoride concentration of 5 mg/L, only 73% of the fluoride is removed. This results in a fluoride level that is 1.35 mg/L after treatment, which is significantly less than the 1.5 mg/L permitted limit defined by IS 10500 - 2012. The removal rate is 95% at a starting fluoride concentration of 20 mg/L, leaving a residual fluoride concentration of 1 mg/L.

The amount of fluorides removed is significantly impacted by the pH variation of the sample. With a drop in pH, the percentage removed rose. Although the percentage reduction is modest at lower fluoride beginning concentration levels, the water after treatment nevertheless conforms well with the permitted fluoride limits set by IS 10500 - 2012.

It follows from the study that as Tulsi powder dosage increased, so did the percentage of removal.

Fluoride elimination increased with contact time, reaching its maximum during a 3-hour contact period.
