      다국어 초록 (Multilingual Abstract)

      To minimize fouling in ultrafilitration process, pretreatment such as coagulation, ozone, or activated-carbon is required.
      In this study, activated carbon adsorption was applied as pretreatment to UF process. Batch experiments were conducted to test the performance of ultrafiltration following activated carbon adsorption. The model of particle trajectory was used to compare with the experimental results. Sensitivity analysis was also performed to predict the better operation conditions in adsorption and ultrafiltration.
      Sensitivity analysis showed that the linear velocity was one of the main factors to maintain the high permeate flux in the pretreatment process using activated carbon. Fouling would be efficiently decreased by the active lateral-migration of suspended particles when the linear velocity of higher than 80cm/sec was used.
