Defluoridation of drinking water using a new flow column-electrocoagulation reactor - Experimental, statistical, and economic approach
The results obtained showed that 98% of fluoride was removed within 25 min of electrolysis at pH of 6, ID of 5 mm, and CD of 2 mA/cm.sup.2. The general relationship between fluoride removal and operating parameters could be described by a linear model with R.sup.2 of 0.823. The contribution of the operating parameters to the suggested model followed the order: t > CD > C.sub.0 > ID > pH. The SEM images obtained showed that, after the EC process, the surface of the anodes, became non-uniform with a large number of irregularities due to the generation of aluminium hydroxides. It is suggested that these do not materially affect the performance. A provisional estimate of the operating cost was 0.379 US $/m.sup.3. Additionally, it has been found that 0.6 kW/m.sup.3 is potentially recoverable from the H.sub.2 gas.
