This study has studied the dissolvability of natural organic substances from drinking water (DOM) through the process of electrocoagulation (EC). For this purpose, raw water samples were taken from the entrance of the Sivas drinking water treatment facility, where the waters of the Sivas 4 September Barge were purified. The measurement of processing efficiency has taken into account the soluble organic carbon (CO) and UV254 absorption parameters. The effect of operating parameters such as the starting pH, current intensity and electrolysis time in the EC reactor where the monopols of iron and aluminum electrots are used parallelly connected is studied on the COC and UV254 absorption discharge. In the EC process in which aluminum electrots were used, the starting pH, flow intensity and electrolysis time optimum values were found respectively; 5, 20 A/m2 and 20 minutes. Under these conditions, the COK and UV254 removal effects were obtained respectively; 78% and 94.5% respectively. In the case of the use of iron electrots, the optimal operating conditions were found as the starting pH 6, the flow intensity of 20 A/m2 and the electrolysis time of 20 minutes, in these conditions the COK and UV254 removal effects respectively; 65.4 % and 80.3 %. In addition, the economic assessment of the EC process was made by calculating the operating cost in terms of energy and electrots (aluminium and iron) spending. As a result, the EC process has been shown to be an effective process in removing DOM from drinking water.
