Abstract

Electrolytic soln. for haemodialysis is regenerated from conc. soln. by dilution with deionised water in an appts. having a circuit for introduction of the conc. soln. at a constant rate and a second circuit for introduction of water. The water flow rate is controlled in response to an instrument sensing the final concn. This instrument is typically a conductivity meter and its output signal may be used to provice "on-off" or continuous control. For use with homehaemodialysis machines, the appts. is compact and relatively inexpensive. It des not require skilled operators.
