Abstract
An operation method of a hollow fiber membrane module is described, the operation method including: a filtration step of performing cross-flow filtration by supplying a feed to an outer surface side of a hollow fiber membrane, in which in the filtration step, a ratio of a viscosity μf of the feed to a viscosity μp of a filtrate satisfies a relation of μf/μp≥1.5, and a flow rate ratio of a flow rate vp of the filtrate to a flow rate vf of the feed satisfies a relation of 0.02≤vp/vf≤0.3.
