영문 초록

To evaluate the effectiveness of water treatment using nanofiltration, ultrafiltration, and microfiltration systems, tapwater contaminated by bacteria and nitrate nitrogen was filtered, and then the rates of removal for many kinds of contaminants were comp.ared and investigated. The rates of turbidity removal by these systems are around 80% all of them. However, nanofiltration system is the most effective as hardness removal is 80%, suspended solids 90%, total residual chlorine 90% and nitrate nitrogen 69%. Among nanofiltration, ultrafiltration and microfiltration systems, nanofiltration system is the most stable in flow rate of permeate. Comparing hollow and spiral type of ultrafiltration, microfiltration each, spiral type is more stable than hollow type owing to rinsing effect of brine. The values of pH in ultrafiltration and microfiltration systems are between 7, 0 and 7.5, and that of nanofiltration system is low to 6.2-7.0. The effectiveness of heterotrophic bacteria removal is the most excellent in the nanofiltration system.
