[0002] When separating feed liquids, polymer membranes use a feed pump and a circulation pump to pass small molecule solute particles from the high-pressure feed liquid side through the membrane to the low-pressure side. The permeate is discharged, while the polymer group is retained by the membrane. Therefore, a membrane device that increases the production of macromolecular dextran has emerged.
