Introduction: microbiological contamination of the hemodialysis water treatment is a present problem mainly because of the persistence of certain microorganisms in the biofilm formation, such as the case of Pseudomonas aeruginosa. Objective: to update the knowledge on the health importance of Pseudomonas aeruginosa and their disinfection in hemodialysis water for adequate decision-making. Methods: data were taken from international bodies such as the Association for the Advancement of Medical Instruments, the International Standardization Organization, expert criteria and lab results as well as work guidelines. Information synthesis: there are different ways of acting upon the bacterial contamination; one of them is to prevent it. This can be accomplished if certain elements of the system are improved to create a turbulent flow that prevents the presence of biofilm; it may also be attained by using heat or disinfectant chemical products that should be validated. However, for the purpose of preventing the presence of Pseudomonas aeruginosa and other microorganisms, emphasis must be made on regular and preventive cleaning and disinfection of all the parts of the water treatment and distribution systems and of the hemodialysis equipment. Conclusions: the process of disinfection of Pseudomonas aeruginosa in a water treatment plant is casuistic, taking into account the diversity of water treatment systems, distribution systems, operating time and need of taking point measures aimed at each of them.

Keywords : Pseudomonas aeruginosa; disinfection; hemodialysis water.
