A field study and continuous removal of fluoride in a packed column.

ABSTRACT

The synthetic water performance in the light of fluoride removal was studied and compared with the actual fluoride contaminated water of different selected water collection stations. An indegeneous activated alumina was used as adsorbent. The performance of the column for fluoride contaminated water was about 94% fluoride reduction at a pH value of 7.0 and the presence of total dissolved solids (T.D.S.). 2114 mg/L in subsoil water decreased the fluoride removal by 5%.
