As techman has highlighted the presence of Chrlorine Dioxide in the water can cause hemolysis. Where is your water from this treatment taken being supplied from? Is it possible that the Estates Dept have added Chlorine Dioxide to the supply and not advised the Renal Unit?
What does your suppy system consist of, Charcoal Filters, Central RO?
Can the supply be tested using a DPD kit? (Between Carbon Filters) This wll detect Chlorine and Chloramine.
Has this occured with just the one patient, is it possible the machone has not been rinsed properlly post bleaching?
