An Experimental Study of Electrocoagulation Process Applied For Influence of Fluoride Ions on Hardness Removal
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 1
Abstract
This paper demonstrated influence of fluoride ions on hardness removal and simultaneous removal efficiency from water by Electrocoagulation process. The process parameters such as initial pH, applied voltage, DO level and Electrolysis time were studied. Electrocoagulation test results revealed that a maximum hardness removal 60-70% for the concentrations of hardness of 800, and 1000 mgL-1 and a removal of 91% for fluoride concentration of 5 mgL-1 investigated at an applied voltage of 15 V and an electrolysis time of 120 minutes. Hardness removal by Electrocoagulation majorly involves adsorption on to iron flocs, while fluoride replaces a hydroxyl group from iron aggregates. In this paper, influence of fluoride ions on hardness removal was investigated and gave a marginal increase in hardness removal. This paper also include the important parameter DO level that plays a key role in the elctrocoagulation process.
