FIELD: process engineering.
SUBSTANCE: invention relates to hollow-fiber membrane module including fixing layer whereto one or multiple packs of hollow-fiber membranes are secured by moulded resin, each pack including multiple hollow-fiber membranes. Hollow part of each hollow-fiber membrane is exposed at one or both ends while pack of said membranes is divided into set of small packs nearby one of said fixing layers on exposed side of open part. Outer side of every small pack is coated with elastic material nearby fixing layer filtration part interface.
EFFECT: stable long-term filtration.
