Abstract
The present invention constitutes dialysate formulations that are suitable for use in preparing dialysate solutions for use in batch and/or proportioning systems and for improving dialysis efficiency by reducing or preventing clotting of the dialysis flow paths. The dialysate chemical formulations for one batch of dialysate comprise an acid concentrate stored in a first vessel, and a citrate-containing bicarbonate concentrate stored in a second vessel. The contents of the first and second vessels are emptied into a dialysate preparation tank and mixed with water to form a batch quantity of dialysate solution. Alternately, a dry acid and/or a dry citrate-containing base concentrates are dissolved separately in measured quantities of water to form liquid concentrates which are then used in conjunction with a proportioning machine to generate on-line a final dialysis solution stream.
