1. A control system for a blood treatment apparatus, said control system comprising:
a memory; and
a processor in operable communication with the memory, the processor configured to:
instruct an operator to install a first flow circuit for conducting a fluid provided by the blood treatment apparatus through a dialyzer;
instruct the operator to install a second flow circuit that is separated from the first flow circuit by a semi-permeable membrane of the dialyzer, the second flow circuit comprising connectors for connection to a vascular system of a subject during blood treatment, wherein the second flow circuit is configured to be disconnected from the vascular system and form a closed loop that includes a sterilizing filter;
operate the blood treatment apparatus to pump a human-compatible fluid into the first flow circuit so that a portion of the human-compatible fluid flows through the semi-permeable membrane into the second flow circuit; and
operate the blood treatment apparatus to circulate said portion of the human-compatible fluid in the closed loop of the second flow circuit, to thereby sterilize said portion of the human-compatible fluid by the sterilizing filter.
