The Grundfos Oxiperm Pro system ensures effective disinfection of water in a series of application areas Legionella control begins here The problem Naturally, the water we drink and shower in has to be clean if we are to stay healthy. Unfortunately, one of the most widespread health hazards in drinking water installations worldwide is connected to exceptionally resistant bacteria – legionella. Legionella exist mainly in hot water systems with a low flow rate, areas of stagnation or badly serviced hot water tanks. A layer of slime in the water pipes called biofilm is the habitat for...

Disinfection facts Tough problem – gentle solution What are legionella bacteria? Legionella bacteria are the primary source of legionnaire’s disease – a potentially fatal disease, particularly for those with a weakened immune system. It is estimated that legionnaire’s disease is responsible for 15-20,000 deaths in Europe every year.∗ Legionella bacteria and the biofilm where they live and feed are highly resistant to most disinfection methods. That makes effective combat against them difficult, and their successful elimination calls for specific and highly specialised solutions....

The chemistry of great benefits Removes both free legionella and biofilm The Oxiperm Pro system uses chlorine dioxide for the disinfection of water. This particular chemical compound presents a number of advantages that cannot be matched by any other disinfection method. Legionella bacteria grow and reproduce in biofilm as does 90% of all bacteria in water systems. Biofilm is a layer of slime that exists in water pipes and especially in hot water tanks. Chlorine dioxide diffuses into the biofilm and destroys it from within, whereas other disinfectants only attack the surface of the film. No...

Typical dosing rates in building applications are between 0,1 and 0,4 g/m³. The required total consumption and maximum flow requirement depends on the building type. There is a big difference in annual water consumption, daily maximum consumption and the peak consumption in a block of flats compared to a five star hotel. If you have no reliable flow measurements in the building, the table below gives you an example of how to calculate peak water flow in various types of buildings in order to select the right Oxiperm Pro. Example of calculation of maximum hourly flow rate in a 200-bed hotel...

Injection points Injection of chlorine dioxide into the water system can be done wherever it is deemed suitable. If a total disinfection is desired, the injection point should be located where the water main enters the building. In most cases, it is sufficient to treat only the hot water system where there is the highest risk of bacteria growth.
