Raw material liquid concentration system

Abstract

Provided is a system preventing or reducing adhesion of a raw material component to a membrane surface and increasing the recovery rate of the raw material component after concentration. A raw material liquid concentration system for a medicine production process comprising a forward osmosis membrane unit having a forward osmosis membrane, and a raw material liquid side space and an inductive solution side space which are separated from each other by the forward osmosis membrane; a raw material liquid channel supplying, to the raw material liquid side space, a raw material liquid containing a solvent and a solute; an inductive solution channel supplying, to the inductive solution side space, an inductive solution containing an inductive material; a concentrated liquid channel removing a concentrated raw material liquid from the forward osmosis membrane unit; and a diluted inductive solution channel removing a diluted inductive solution from the forward osmosis membrane unit.
