ELEKTROKOAGÜLASYONLA ARSENİK GİDERİMİNDE AKIM YOĞUNLUĞUNA BAĞLI OLARAK ENERJİ TÜKETİMİ ve GİDERİM ORANININ BELİRLENMESİ
DETERMINATION OF ENERGY CONSUMPTION AND REMOVAL RATE DEPENDING ON CURRENT DENSITY FOR ARSENIC REMOVAL BY ELECTROCOAGULATION

Summary/Abstract: The fact of high arsenic limit in drinking water in cities causes various health problems. Arsenic (As) pollution is observed due to natural reasons (geological structure and arsenic rich soil) in the water resources with contamination from human activities. The maximum amount of arsenic in drinking water is determined as 10 μg / L by World Health Organization and concentrations above this value is declared as toxic water. The higher As amounts from maximum admissible level in drinking water should be removed. In this context, it is aimed to investigate the arsenic removal from waters by electrocoagulation (EK) method, which is known as a cheap and easy method and preferred due to its simplicity in operation. The electrocoagulation process is an electrochemical process for the treatment of contaminated water and is a water treatment technology used to remove a wide range of pollutants. A 10 L electrocoagulator was designed for electrocoagulation experiments. Five electrode plates with a surface area of 180 cm2 were used in the system. The clearance between each electrode is 5 cm. As a power source, the GPS-3303 6020 1200 Watt model is used with a maximum of 30 volts and 3 A current. The voltage is between 5V-15V and the current is determined as 1A2A. As a result of the experimental study, over 95% of the As were removed at the end of 10 minutes. Optimum current conditions were obtained at 5 V and 2 A values. Since there is no significant change in the treatment efficiency in high flow conditions, it is recommended not to exceed 5 volts in order not to increase the cost.
