- In seawater, plankton and suspended solids causes a problem in operating a seawater pretreatment system. Since such substances are filtered as they pass through pretreatment equipment, the importance of pretreatment emerges. This study used disc filters and UF membranes as the pretreatment equipment. As the processes of filtration and washing were repeated, flow and velocity would change as time passed. So it seems that steady experimental conditions not be achieved. This study conducted a fouling analysis using two flow conditions: constant r.p.m and constant flow rate regarding the conditions of flow in the process of filtration. For the fouling analysis, TMP(Trans Membrane Pressure) and permeability were analysed, and turbidity and SDI(Silt Density Index) value were compared. Each specimen was sampled, measured and compared using a measuring instrument.
