Abstract: Provided is a filtration membrane for which a nonwoven fabric formed from synthetic fibers having hydrophilicity is used. The membrane is employed as a filtration membrane which can be used for a treatment system for seawater, river water, and the like and provides a high filtration flow velocity, sufficient recovery of the filtration flow velocity by backwashing or washing with a chemical, and a long lifetime. In particular, provided is a filtration membrane fabricated using a nonwoven fabric produced by hydrophilizing hydrophobic fibers by a material having a hydrophilic functional group, based on a method such as application of a hydrophilic resin to respective surfaces of hydrophobic resin fibers or copolymerization of a hydrophilic component. Also provided is a filtration unit and a filtration apparatus for which the filtration membrane is used, as well as a filtration method for filtrating seawater and/or freshwater by this filtration apparatus.
