Abstract
A catchment header allowing a plurality of membrane modules to be connected thereto, having a tubular catchment part with a Young's modulus of 4.0 GPa or less for collecting and taking out filtrated liquid from the membrane modules, wherein at least a part of the tubular catchment part is covered with a reinforcement member with a Young's modulus of 4.0 to 250 GPa, the tubular catchment part of the catchment header is preferably formed of a synthetic resin, and the cross sectional area thereof perpendicular to the longitudinal direction of the tubular catchment part is preferably 4 to 36 cm2.
Claims16
A catchment header comprising:
- a tubular catchment part including a plurality of membrane module connection parts at the side surface and having a Young's modulus of 4.0 GPa or less for collecting and removing filtrated liquid 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 the side surface of the tubular catchment part.
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.
