The present invention also provides a fine filtering system to reduce time required for a filtration process and thus, the efficiency of the process is increased. According to an aspect of the present invention, there is provided a fine filtering system including : a filtering apparatus in which a source water tank is connected thereto through a source water inlet pipeline and a filter media is disposed in the filtering apparatus, wherein source water flowing through the source water inlet pipeline is filtered using the filter media so as to become filtered water; a chemicals storage tank in which chemicals used to condense suspended solids remaining in source water are stored, wherein the source water flows into the filtering apparatus from the source water tank; and a re-filtering apparatus with which the filtering apparatus is combined and a re-filter media is disposed in the re-filtering apparatus, wherein filtered water discharged from the filtering apparatus is re-filtered using the re-filter media and thus becomes treated water to be used for water supply.
