14. A catchment header adapted to be immersed in a fluid that is to be filtered, said catchment header adapted to receive and be connected to a plurality of membrane modules which are to be immersed in the fluid to be filtered, said catchment header comprising:
-
a hollow tubular-shaped catchment part formed from synthetic resin for collecting and removing filtered liquid from a plurality of the membrane modules, wherein said hollow tubular-shaped catchment part has a side surface, a Young'"'"'s modulus of 4.0 GPa or less, a plurality of membrane module connection parts on said side surface that are each adapted to receive and be connected to a respective membrane module, and at least one outlet for removing the filtered liquid collected from a plurality of membrane modules, and a reinforcement member having a Young'"'"'s modulus of 4.0 GPa to 250 GPa which covers at least a part of said hollow tubular-shaped catchment part. - View Dependent Claims (15, 16)
