| This paper shows the simulation of electric field distribution and removing characteristics of Escherichia coil for discharge tube with globular SiO₂ bead. At the experiments of the removing Escherichia coil used the pyrex discharge tube with dielectric(SiO₂) bead, because the electric field inner discharge tube is increased when applied voltage is increased. And the removed ratio of Escherichia coil was related with applied voltage. When a passing number of test water in discharge tube is increased, the removed ratio of Escherichia coil is increased because passing number of territory with electric field is increased. And when diameter of dielectric(Si0₂) bead is increased, the removed time of Escherichia coil was decreased because electric field for dielectric polalization of dielectric(SiO₂) bead was increased. Also, the removed ratio of Escherichia coil of the discharge tube with SiO2 bead was measured higher than the removal ratio of the discharge tube without SiO2 bead. And if reactor has air bubble, the removal ratio of Escherichia coil was measured higher than the removal ratio of Escherichia coil without bubble. |
