ABSTRACT
The purpose of the research sought to assess the elimination of
fluoride through drinking water by electrocoagulation (EC) in batch
or continuous-flow reactors with a variety of usage circumstances.
The implications of altering applied voltage, initial concentration,
and initial pH on fluoride elimination effectiveness have been
studied utilizing mild steel electrodes. The findings with distilled
water and groundwater have been compared. The best F- efficiency of
elimination through distilled water was 84.9% and 79.4% in batch and
continuous mode, accordingly, under the maximum applied voltage of
25 V. The elimination effectiveness through groundwater was 79.6%
and 28.7% in batch and continuous modes, correspondingly. Despite
minimal F- content levels of 10 mg/L and initial pH values that
varied between 5 and 10, the final pH ranged from 6.35 to 7.96,
demonstrating the superiority of EC over traditional coagulation for
drinking water treatment. The highest F- elimination effectiveness
of 84.9% was noticed under an initial pH of 6.42. Raising the level
of fluoride from 20 mg/L to 50 mg/L caused a pH rise regardless of
the voltage used. Thus anticipated, increased starting F-
concentrations contributed to lower F- effectiveness in elimination.
These findings highlight the significance of starting F- contents in
determining both the final pH of treated water
and F effectiveness in elimination.
