N2 - A 50 Hz low-frequency electromagnetic field (LF-EMF) could give removal effect on the growth of Escherichia coli (E. coli) in the riverbank filtration (RBF) was studied. The LF-EMF strengths were varied from 2 to 10 mT using coil column induce magnetic fields. For this study, two different columns with a diameter of 50 mm and 80 mm were applied; 1.5mm copper wires with the number of turns between 300 to 600 turns. Water samples were flowed into the column at flowrate of 50mL/min with temperature in range of 28-30°C. This study, it was found that the LF-EMF has significant removal effects on E. coli growth, where the removal of 100% of E. coli at 6 mT and 8 mT after 6 hrs exposed. Moreover, for shorter exposure period of 3 hrs exposed, 82% of E. coli removal were detected in 80 mm column for 8 mT and 10 mT magnetic field. These findings indicate that the application of LF-EMF is able to decrease the E. coli, can be and efficient in E. coli growth from river water intake. Thus, the results from this study proved that the utilization of LF-EMF is able to decrease the concentrations of E. coli, and contributes in slowing down their growth. Also, it can be indicated that the LF-EMF kill a part of E. coli exposed in the river water with the large magnetic field and long-time exposure.
