lüll Current understanding of ozone use for disinfecting hemodialysis water treatment systems Tarrass F; Benjelloun M; Benjelloun OBlood Purif 2010[]; 30 (1): 64-70BACKGROUND: Water treatment systems are susceptible to microbial contaminations and periodical disinfection procedures are mandatory to obtain results requested from international standards. According to the Association for the Advancement of Medical Instrumentation, ozone is the most effective method to destroy microorganisms, and to prevent, reduce or remove the biofilm. This study aims to review the literature on the application of ozone in the disinfection of water treatment systems for hemodialysis. METHODS: Data were obtained from databases (Ovid MEDLINE, Cochrane, EMBASE, and others). RESULTS: Ozone is quite effective in killing bacteria and degrading endotoxins and biofilm, with efficacy being concentration- and time-dependent. However, being a strong oxidant, appropriately compatible materials should be used. Also ozone production should be monitored and its level in ambient air should also be checked periodically to maintain a contamination air standard of 0.1 ppm. CONCLUSION: Ozone appears to be promising in hemodialysis. However, further investigations are necessary to approve its wider use.|Equipment Contamination/prevention & control[MESH]|Equipment Safety/*methods[MESH]|Hemodialysis Solutions/therapeutic use[MESH]|Humans[MESH]|Ozone/*chemistry/pharmacology[MESH]|Renal Dialysis/instrumentation/*methods[MESH]|Water Microbiology[MESH]|Water Purification/*methods[MESH]|Water/*chemistry[MESH] |
