Abstract:
1. A fractionation device for separating one or more solutes from a raw liquid with a membrane comprising: 1) a supply part for loading the raw liquid; 2) a filtration part connected to the supply part by a flow channel for filtering out one or more solutes from the raw liquid received from the supply part to produce a filtrate; 3) a concentration part connected to the filtration part by a flow channel for increasing the concentration of one or more solutes in the filtrate received from the filtration part to produce a concentrated solution; 4) a recovery part connected to the concentration part by a flow channel for recovering the concentrated solution obtained in the concentration part; and 5) one or more flow pumps operatively connected to one or more of the supply part, filtration part and concentration part for moving liquid through the fractionation device, wherein the filtration part, the concentration part, and the flow channel connecting the filtration part and the concentration part form a closed circuit; and
