In this work, an airlift reactor with internal loop using electrocoagulation technology for superficial raw water treatment has been studied. The objective was the evaluation of the effect of applied voltage on turbidity reduction.For this purpose, synthetic solutions with known turbidities were prepared and tested. The airlift reactor has two parallel compartments, separated by a partition: an upward flow compartment, called riser, in which aluminum electrodes were immersed, and another down flow compartment called downcomer. Different potentials generated by an electric generator were applied on electrodes (0 to 12 Volts). During electrocoagulation, small gas bubbles generated on electrodes (hydrogen at the cathode and oxygen at the anode) cause recirculation synthetic solutions between the riser and the downcomer. Evaluation of removal performance of the turbidity in the reactor internal airlift loop with electrocoagulation led to conclusive results. The yield increases with time, it is best when the applied voltage increases. At 12 V, it reached 96%.
