Methods of minimising the effect of integrity loss in hollow fibre membrane modules
View Patent ↗A method and apparatus for reducing the effect of integrity loss in a hollow fiber membrane module, said module including a plurality of hollow fiber membranes ( 5 ), at least one end of the fiber membranes ( 5 ) being supported in a pot ( 6 ), the method including the step of increasing flow resistance of the liquid through the lumen ( 8 ) of the fiber membrane ( 5 ) in the region of the pot ( 6 ).
1. A method of reducing an effect of an integrity loss in a hollow fibre membrane module, the module comprising a plurality of hollow fibre membranes, each hollow fibre membrane comprising a lumen, wherein at least one end of each of the hollow fibre membranes is supported in a pot forming at least one potted segment of the lumen and a remaining segment of the lumen, the method comprising:
increasing a flow resistance of a liquid through the at least one potted segment of the lumen, whereby an effect of an integrity loss is reduced,
wherein increasing the flow resistance through the at least one potted segment of the lumen comprises plugging an end of the lumen with a porous material in a region of the pot.
