Fluoride Removal Crushed Limestone Calcite Wiki

Pre-acidified fluoride water using two edible acids viz. acetic acid AA and citric acid CA have been used for treatment by crushed limestone of diameter 3-4 mm to precipitate fluoride as CaF 2 in addition to adsorption of fluoride on limestone. The study has been carried out in batches by varying the acid concentration and contact time.

Pdf Fluoride Removal From Water Using Crushed Limestone

An examination of defluoridation by industrial grade limestone indicated that a combination of precipitation and adsorption of fluoride can be more effective for defluoridation of water. Pre-acidified fluoride water using two edible acids viz. acetic acid AA and citric acid CA have been used for treatment by crushed limestone of diameter 3-4 mm to precipitate fluoride as CaF 2 in .

Fluoride Removal By Calcite Evidence For Fluorite

Oct 04 2005 When HCl-cleaned calcite was used the observed fluoride removed was similar to that of raw crushed limestone but constitutes 5.1 1.2 of the available number of adsorption sites. These results compare to a removal of 0.4 determined by Fan et al. 6 using a calcite size fraction of 212 to 250 m with a surface area of 0.0057 m2g 4.72 x .

Fluoride Removal By Hydrothermally Modified Limestone

Mar 01 2016 Reardon et al. reported that bubbling of CO 2 through crushed limestone-bed column can reduce fluoride from 10 mg L 1 to 2 mg L 1 by precipitation of fluoride as CaF 2. Turner et al. reported that both precipitation of CaF 2 and adsorption of fluoride on limestone surface are dominant mechanisms of fluoride removal by limestone treatment .

A Study Of Suitability Of Limestone For Fluoride Removal

Dec 01 2020 Fluoride removal quantitatively related with surface area porosity and density of limestone. Fe 2 O 3 and Al 2 O 3 impurities make the pH of treated water more acceptable for drinking. The results may help in screening limestone for use in fluoride removal by PACLT.

Fluoride Removal From Contaminated Water By Limestone

This fluoride removal efficiency was higher than with the limestone reactor of Reardon and Wang by a further reduction of 1.19 mgL fluoride in total yet still lower than the predicted efficiency. One important reason of the lower fluoride removal efficiency than with prediction is that the citrate ions suppressed the precipitation of calcite.

Fluoride Removal From Groundwater By Limestone Treatment

Apr 01 2015 The present work reveals that addition of dilute phosphoric acid to the influent water before treatment with crushed limestone can efficiently remove fluoride from groundwater. Fluoride removal from initial 0.526 mM to final 0.5052.6 M along with near neutral pH of the treated water has been achieved with 10 mM initial phosphoric acid in 3 h.
