  • Patent number: 12702961
    Abstract: Even when the flow rate at which liquid is supplied varies, the variation in the resistivity of resistivity-adjusted liquid is suppressed by using a simple structure. The hollow fiber membrane module is sectioned into a liquid-phase region and a gas-phase region by hollow fiber membranes. The liquid-phase region receives liquid L whose resistivity is to be adjusted. The gas-phase region receives adjustment gas G used to adjust a resistivity of the liquid L. The module passage pipe communicates with the liquid-phase region of the hollow fiber membrane module, the liquid supply pipe, and the liquid discharge pipe and passes through the hollow fiber membrane module. The bypass pipe communicates with the liquid supply pipe and the liquid discharge pipe and bypasses the hollow fiber membrane module. The bypass pipe includes a laminarization unit including a plurality of thin tubes thinner than the module passage pipe.
