9. 2 At 40 C ANODIX reduced the number of legionella bacteria from 100 000 per ml to 1 000 per ml in about 3 hours figure 3 The difference clearly shows that legionella bacteria are more resistant than Pseudomonas bacteria and that they reproduce more rapidly at higher temperatures The deactivation with ANODIX occurred despite the extremely low chlorine content of the water This is primarily due to the treatment of the entire water flow with the pipe shaped radial special electrodes which fill the whole pipe diameter Based on the test results stated above it can be concluded that with ANODIX for disinfection of a water system infected with legionella or pseudomonas bacteria you have a system which can substitute the heating of the water to 60 C ANODIX can also be utilized for disinfecting cold water which feeds the hot water system ANODIX patent pending is available in three designs 1 The standard version type S for prevention of legionella attacks and for decontamination of systems with weaker bacteria attacks with a depot effect in the whole pipe system 2 Type M and type L consist of an ultrasound reactor and anodic oxidation for opening of the amoebas and destruction of legionella bacteria with a depot effect in the pipe system for older systems which are conducive to strong bacteria attacks Air humidifier ae Fresh air Anodix type S Anodix S installed in the air humidifier of an air conditioning unit
