      Parameters:
      inletStream - a StreamInterface object

    • getPermeateStream

      public StreamInterface getPermeateStream()

      Getter for the field permeateStream.

      Returns:
      a StreamInterface object

    • getInletStream

      public StreamInterface getInletStream()
      Gets the inlet stream.
      Returns:
      inlet stream

    • getRetentateStream

      public StreamInterface getRetentateStream()

      Getter for the field retentateStream.

      Returns:
      a StreamInterface object

    • getInletStreams

      public List<StreamInterface> getInletStreams()
      Returns all inlet streams connected to this equipment. Subclasses override to report their specific inlets. Used by graph builders, DEXPI export, and auto-instrumentation to discover topology without instanceof checks.
      Returns:
      unmodifiable list of inlet streams (empty by default)

    • getOutletStreams

      public List<StreamInterface> getOutletStreams()
      Returns all outlet streams produced by this equipment. Subclasses override to report their specific outlets. Used by graph builders, DEXPI export, and auto-instrumentation to discover topology without instanceof checks.
      Returns:
      unmodifiable list of outlet streams (empty by default)

    • setMembraneArea

      public void setMembraneArea(double area)
      Set membrane area used for permeability calculations.
      Parameters:

    • getMembraneArea

      public double getMembraneArea()
      Gets the membrane area.
      Returns:
      membrane area in m^2

    • setPermeability

      public void setPermeability(String component, double permeability)
