Removal of Turbidity From Water by Electrocoagulation Technique.

Abstract

This study search’s the removal of turbidity from water by electrocoagulation technique. Bench scale with continuous flow system was designed the system consists of electrocoagulation reactor with volume (2 L), flocculation basin and sedimentation basin with volumes change due to the change in detention time of electrocoagulation. Aluminum plates (17×8) cm were used (3 plates) as the anode and (4 plates) as the cathode, the spacing between plates was taken (1 cm) and the temperature of water was kept at (25°C). The study investigates the effects of some operating parameters such as, electrical current that ranging from (0.1 – 2) A, detention time of electrocoagulation (1 , 5 , 10 , 20) minutes and initial turbidity variety of the raw water (10 , 25 , 100 , 300) ntu upon the residual turbidity. Experiment result shows that the residual turbidity decrease with increase value of the electrical current for all values of initial turbidity. Also, the residual turbidity decrease with increase time of electrocoagulation for all values of initial turbidity specialy in (0.1 , 0.25 , 0.5) A, when the electrical current increase to (1 , 1.5 , 2) A , the change in residual turbidity was small specialty in time between (10 – 20) minutes. The results also proved that increasing the initial turbidity lead to increase the residual turbidity.
