Abstract

Disclosed are systems and methods of preparing dialysate for use in a home dialysis system that is compact and light-weight relative to existing systems and consumes relatively low amounts of energy. The method includes coupling a household water stream to a dialysis system; filtering the water stream; heating the water stream to at least about 138 degrees Celsius in a non-batch process to produce a heated water stream; maintaining the heated water stream at or above at least about 138 degrees Celsius for at least about two seconds; cooling the heated water stream to produce a cooled water stream; ultrafiltering the cooled water stream; and mixing dialysate components into the cooled water stream in a non-batch process.

A method of preparing dialysate for use in a dialysis system, comprising:

coupling a household water stream to a dialysis system;
filtering the water stream;
heating the water stream to at least about 138° C. in a non-batch process to produce a heated water stream;
maintaining the heated water stream at or above at least about 138° C. for at least about two seconds;
cooling the heated water stream to produce a cooled water stream;
ultrafiltering the cooled water stream;
and
mixing dialysate components into the cooled water stream in a non-batch process;
and
wherein the water flows through a single fluid microfluidic heat exchanger during the heating, maintaining and cooling steps.
