  • Reciprocating freeze concentration for urine-based fertilizer production
    Patent number: 11897822
    Abstract: A system for generating a concentrated product from a feedstock includes a reciprocating concentration system that includes first and second chambers to which the feedstock is alternately provided and from which the concentrated product is alternately removed, and a heat transfer system in thermal communication with the first and second chambers, the heat transfer system being configured to reversibly transfer heat between the first and second chambers such that the first chamber alternates between melting a frozen portion of the feedstock in the second chamber and having a frozen portion of the feedstock in the first chamber melted by the feedstock in the second chamber. The system further includes a heat dump system in thermal communication with the reciprocating concentration system, the heat dump system being configured to remove heat from the reciprocating concentration system.
