Abstract

This cartridge type hollow fiber membrane module is provided with: a housing; a plurality of hollow fiber membranes accommodated in the housing; a first potting section bundled in a state in which a first end part of the hollow fiber membranes forms an opening; a second potting section bundled in a state in which a second end part of the hollow fiber membranes forms a seal; an affixing section that affixes the first potting section attachably and detachably to the housing; a seal section that creates a watertight seal between the first potting section and the housing; and a holding section that holds the second potting section attachably and detachably to the housing and allows liquid to pass between the second potting section and the housing.

Description

technical field [0001] The present invention relates to a cartridge-type hollow fiber membrane module used in the fields of water treatment, fermentation industry, pharmaceutical manufacturing, food industry and the like. Background technique [0002] Fermentation method is a material production method involving the cultivation of microorganisms and cultured cells, and can be roughly classified into (1) batch fermentation method (Batch fermentation method) and fed-batch fermentation method (Fed-Batch fermentation method) and (2) continuous fermentation method . [0003] Regarding the above-mentioned (2) continuous fermentation method, the following method has been proposed: use a separation membrane to filter microorganisms and culture cells, recover chemicals from the filtrate, and at the same time make the microorganisms and culture cells in the concentrated liquid be maintained or refluxed in the fermentation culture liquid, Thereby maintaining a high concentration of mi...
