    Abstract: Provided are filter media for liquid filters and a method of manufacturing the same, in which a thin filter layer is formed and the content of nanofibers weighs light, by laminating a low weight nanofiber web on a porous nonwoven fabric, and thus a less differential pressure is applied before and after filtering, to thereby increase a pass flow rate. The filter medium includes: a porous support that plays a strength support role; and a nanofiber web that is laminated on one side of the porous support and is made of nanofibers of a polymer material, in which the nanofiber web comprises fine pores of a three-dimensional structure, through which a liquid to be treated passes, wherein content of the nanofibers is less than 5 gsm.

    Abstract: A filter apparatus includes: a housing having an inlet for supplying sewage or waste water into the housing, and an outlet for discharging purified water from the housing; and filter media arranged inside the housing. Each of the filter media includes: a porous substrate; a nanofiber web laminated on both surfaces of the porous substrate; and a fuse reinforcement material interposed between the nanofiber web and the porous substrate. The porous substrate is surrounded by the nanofiber web except for an upper edge of the porous substrate to form a protruding portion. The apparatus further includes: a discharge pipe connected to the outlet and including a fixing portion fixed to the protruding portion of the porous substrate and a connection tube connected to the fixing portion and connected to the outlet; and a pump connected to the outlet for pumping the purified water out of the housing.

    Abstract: A filter medium includes: a porous substrate; a nanofiber web laminated on both surfaces of the porous substrate, the nanofiber web being formed of accumulated nanofibers made of a polymer material and having a number of fine pores; and a fuse reinforcement material interposed between the nanofiber web and the porous substrate for adhesion with the nanofiber web and the porous substrate integrally. The porous substrate is surrounded by the nanofiber web except for an upper edge of the porous substrate, the upper edge of the porous substrate protrudes with respect to the nanofiber web to form a protruding portion, and the protruding portion is configured to be connected with a discharge hole through which purified water via the porous substrate is discharged.
