Document Type and Number:
WIPO Patent Application WO/2018/008723
Kind Code:
A1
Abstract:
To provid: a carrier for microbial adhesion with which it is possible to reduce flattening when used to treat water for a long period, prevent the falling off of fiber and changes to the water flow, etc., and prevent a decrease in the yield of microbes (i.e., improve the yield); and a method for manufacturing the carrier for microbial adhesion. A carrier T6 for microbial adhesion having a nonwoven fabric f1 and a web W1, which comprises a first fiber made of a polyolefin resin and a second fiber made of a polyolefin resin having a melting temperature lower than that of the first fiber, the web W1 being bound to the nonwoven fabric f1, wherein the nonwoven fabric f1 has, on the surface on the opposite side of the surface onto which the web W1 has been adhered, raised fibers K in a lattice shape at a predetermined pitch P1 and a predetermined gauge P2. The raised fibers K are provided by needle-punching from the web W1 side, the predetermined pitch P1 is 2-6 mm on the nonwoven fabric f1, the predetermined gauge P2 is 2-5 mm on the nonwoven fabric f1, and the height of the raised fibers K is 3-10 mm.
