FILTER DEVICE, MANUFACTURING DEVICE FOR CHEMICAL, AND OPERATION METHOD FOR FILTER DEVICE

摘要

Provided is a filter device having separation membrane modules disposed in-series in a plurality of groups, wherein in order to enable efficient transport to the separation membrane modules of a liquid to be filtered and further simplification of equipment, the filter device is provided with a plurality of the separation membrane modules for separating a liquid to be filtered into permeated liquid and non-permeated liquid. The filter device comprises: an in-series non-permeation liquid flow path in which an in-series unit is formed by connecting in series the non-permeation sides of the plurality of the separation membrane modules; and an in-parallel permeation liquid flow path in which an in-parallel unit is formed by connecting in parallel the permeation sides of the plurality of separation membrane modules.
