ABSTRACT:
A system and process for preparation of dialysis concentrate solution from dry chemicals and water. The source of hemodialysis chemicals for a batch is a drum selectively filled with dry chemicals such that an inner core region therewithin is loaded with chemicals which slurry and dissolve the least readily. The required amount of water is metered into a mix tank. Water is pumped from the tank into a spray head fitted over the selectively filled drum. Water is injected onto the chemicals within the inner core region by the use of a nozzle having a narrow spray angle. The chemicals within the inner core region are preferentially dissolved or slurried before the other chemicals within the drum. The slurried and dissolved chemicals are removed from the drum by a suction wand and are entirely solubilized in the tank. Cycling of fluid continues from the drum to the tank and vice versa until all of the chemicals in the drum have been removed. Circulation of the fluid is continued until a uniform solution results. The dialysis concentrate solution is filtered and checked for conductivity prior to dilution in a conventional proportioning system for ultimate use in hemodialysis.
