  • Systems for water extraction for up-concentration of organic solutes
    Patent number: 11813579
    Abstract: The present invention relates to a water extraction system for up-concentration of organic solutes comprising a flow cell comprising a membrane; said membrane comprising an active layer comprising immobilized aquaporin water channels and a support layer, and said membrane having a feed side and a non-feed side; and an aqueous source solution in fluid communication with the feed side of the membrane. The system also includes an aqueous source solution in fluid communication with the feed side of the membrane and an aqueous draw solution in fluid communication with the draw side of the membrane. The aqueous source solution comprises the organic solutes. The membrane module comprises an inlet and an outlet for the aqueous draw solution. The aquaporin vesicles are formed by self-assembly of block copolymers in the presence of an aquaporin protein suspension.

  • Systems for utilizing the water content in fluid from a renal replacement therapy process
    Patent number: 10293094
    Abstract: The present invention relates to systems, methods and uses for recycling at least a part of water lost during various renal replacement therapy processes, e.g. in the preparation of a fresh dialysate solution or fresh reconstitution fluid for kidney disease dialysis and hemofiltration by utilizing water from the spent fluids. The system of the invention is useful in hemodialysis and in peritoneal dialysis as well as in hemofiltration for reuse of water from filtrates and spent fluids. In addition, the system of the invention is useful in the development of a renal assist device or artificial kidney.
