Abstract:

In this study, the process of electrocoagulation (EC) and chemical coagulation (CC) has been studied. The measurement of the processing efficiency has taken into account the outcomes of deformation.In the EC process where iron and aluminum electrots are used, the electrots are linked parallelly to monopols, on the deformation; the type of electrots, the starting pH, the flow intensity and the electrolysis time are influenced. Optimal operating conditions for both electrot materials were found as the starting pH of 7.9, the flow intensity of 10A/m2 and the electrolyte time of 3 minutes. Under these circumstances, the output and operating efficiency of disruption for aluminum and iron electrots are 99% respectively, $0234/m3 and $0247/m3. In the CC process, the type of coagulate substance, the initial pH and the dose of coagulate were studied. Also, the direct costs of the processes are compared by calculation. In the coagulation process where three different types of coagulated substances (Al2(SO4)3.18H2O, FeSO4.7H2O,FeCl3.6H2O) were used, the optimal conditions for all coagulated substances were found at the starting pH7.9 and the coagulated dose was 20 mgMe+/L. In these circumstances, the output and operating efficiency of disruption are calculated respectively; 94.5%, 93.9%, 95.3 and 0.0987 $/m3, 0.0397 $/m3, 0.0328 $/m3.In addition, after the EC and CC process, the filtering process was applied to the drinking water samples and the optimum conditions of process filtration (F) was studied. As a result, it has been determined that the EC process has a higher reliability resolution efficiency than the CC process and is a more economical process.
