This study aims to derive operating properties by membrane material in membrane processes applied to maintain the concentrations of algae harvesting using artificial feed water replicating algae raw water and then to analyze the fouling formation mechanisms. This study selected two types of membranes: polyvinylidene fluoride polymeric membrane representing hydrophobicity and silicon carbide ceramic membrane representing hydrophilicity. Existing Hermia's model was used to analyze the fouling formation mechanisms when inpouring algae. When filtering polymeric and ceramic membranes in high concentrations of artificial algae raw water, it was able to operate ceramic membranes with much higher LMH (L/m2 h). It was confirmed that fouling occurs less frequently due to ceramic membranes' properties such as hydrophilicity and highly negative charge. Hermia's model was used to examine the membrane fouling mechanisms. Both results showed different fouling formation mechanisms. It is considered that this was caused by the hydrophilicity of the polymeric membranes and the relative hydrophobicity of the ceramic membranes. It was confirmed that the fouling tendency varied from membrane materials. Membrane materials are regarded as a major reason. Results, examining the fouling formation mechanisms using Hermia's model is considered as an important factor in fouling control when applying membrane processes from the perspective of algae harvesting.
