NOTCHED WIRE, NOTCHED WIRE ELEMENT AND FILTRATION APPARATUS

摘要

NOTCHED WIRE, NOTCHED-WIRE ELEMENT AND FILTRATION APPARATUS A notched wire 4 that is disposed in layers in a filtration apparatus. First projection stripes 4d are formed on the top surface 4b of a base 4a at prescribed intervals in the longitudinal direction of the base 4a so as to extend in the width direction of the base 4a. Second projection stripes 4e are formed approximately at the centers of the first projection stripe 4d so as to extend between the first projection stripes 4d -4d. The second projection stripes 4e are projection stripes having an approximately semicircular cross section, for example. The second projection stripes 4e is smaller in height than the first projection stripes 4d, and the width of the second projection stripes 4e is shorter than the length of the first projection stripes 4d.
