Abstract
There is disclosed an osmotic concentration cell wherein the flow chamber of the osmotic concentration cell has a continually changing flow path to provide a region of high turbulence to a semipermeable membrane defining the flow chamber. High turbulence at a first semipermeable membrane interface significantly reduces membrane fouling during osmotic concentration and allows for concentration of products with high suspended solids content. The inventive osmotic concentration cell can be used for a variety of purposes including, for example, producing low alcohol wine, concentrating a thin wine into a premium wine, concentrating a low quality grape juice into a higher quality grape juice for fermenting a more premium wine, concentrating various fruit or vegetable juices, and concentrating various beverages, such as teas or coffee.
