This study is related to purification of sugar beet effluents, brine solution and the artificial waste water containing chlorophenol by the use o electrochemical methods which has so many advantages compared to the current purification methods. After the completion of the pre experiments the optimization tests were carried out using Design Expert program with response surface method . The first step was the investigation of the sugar beet effluent obtained from the waste water storage unit. Then it was subjected to a electro purification method using Al electrodes . The effect of solution pH , current density, operation period, upon the turbidity and color removal processes were investigated . A model for the removal of turbidity and color was established by the use of optimum conditions. Then the optimum values were found to be 1mA/cm2, 67.5 dk , 7.5 and 1g/L for the current density, operation time, pH and NaCl concentration respectively which gave %82.1 FTU efficiency for the removal of color and % 83.94 NUT efficiency for the removal of turbidity. In the second part of the study the optimum conditions for the purification of artificial waste water containing phenol, 2-chlorophenol and 4- chlorophenol were carried out using the electrochemical method monitoring the COD values and GC-MS data to find the optimum conditions .The optimum current density , , NaCl concentration, operation time and pH value s were found to be 0.49 mA/cm2, 1.19 g/L, 87.03 min and 7.77 which resulted a COD value of % 59.89.

The final stage of the study was the purification of the brine solution obtained from Konya Cihankur salt plant by the use of EC methods using the current density of 0.70 mA/cm2 and pH value of 8.0 the operation time of 43.24 minutes which resulted %77.21 sulphate, % 85.62 magnesium and % 72.53 calcium removal efficiencies with a COD value % 57.70 . The study was supported as a R&D of brine project by number of 01164.STZ.2011-2 within its SAN-TEZ scheme.
