1 GRUNDFOS alldos Data booklet Reliable preparation and dosing of chlorine dioxide from diluted solutions for water disinfection

2 General General Oxiperm Pro systems produce chlorine dioxide using diluted solutions of sodium chlorite (NaClO,5%) and hydrochloric acid (HCl %). They are available in four capacity levels, producing 5, 10, 30 and 60 g/h of chlorine dioxide respectively. This capacity is sufficient to treat up to 150 m³ of drinking water per hour at the maximum admissible concentration of 0. mg/l ClO. Chlorine dioxide is produced on demand from diluted solutions using the reliable sodium chlorite / hydrochloric acid, in accordance with the German Drinking Water Directive. The chlorine dioxide solution produced is stored in an integrated or external batch tank and is added to the drinking water pipe as required using the integrated dosing pump or an external dosing pump. Applications Usually, disinfection is the first step of pathogen reduction, in order to continue operating a drinking water installation. An ideal means of ensuring the sterility of drinking water is to use chlorine dioxide as a disinfectant. Chlorine dioxide is highly effective against all types of germs and has a long dwell time in the tubing system, which means it disinfects even without re-dosing. The big advantage of chlorine dioxide over other disinfectants is its effectiveness against biofilms. It destroys the existing biofilm, thus removing the breeding ground for microorganisms, and prevents it from building up again. Ideal application areas for Oxiperm Pro include combating germs and pathogens, such as legionella in building installations, disinfecting cooling water systems, and disinfecting drinking water in water plants or industrial processes. Chlorine dioxide is often used in the food and beverage industry for disinfection of process water or for CIP and bottle washing because it doesn t change the taste or smell of the treated water. No chance for pathogens Legionella are rod-shaped bacteria that enter drinking water systems and start to reproduce. Especially in temperatures between 30 and 0 C Legionella reproduce quickly. The bacteria can enter the lungs when a person inhales aerosols containing Legionella when showering. They can cause a life-threatening form of pneumonia known as legionellosis. The ideal breeding ground for legionella in drinking water systems can be found in biofilm, a slimy layer on the inside of water pipes, where other pathogens also build up and reproduce. Legionella also establish themselves in amoebae, which offer them protection against conventional disinfection methods. Using Oxiperm Pro ensures reliable removal of the biofilm with all pathogens and Legionella present in piping and prevents reinfestation. For decontamination, disinfection represents only a part of the accompanying measures, e.g. constructional modifications. Oxiperm Pro OCD-16-5 and -10 systems are designed for small or medium-sized buildings with water flows up to 5 m 3 /h. Oxiperm Pro OCD and -60 systems are suited for disinfection tasks in waterworks or applications in the food and beverage industry Effectiveness diagram 100 Residual germs [%] residual germs with CIO residual germs with HCIO ph >, Concentration of disinfectant [mg/l] HClO = hypochlorous acid ClO = chlorine dioxide

3 General Product benefits Compact system Oxiperm Pro can also be installed in confined spaces, as operation and maintenance are performed exclusively from the front. Low operating costs This intelligent method for producing chlorine dioxide functions with minimal need for chemicals and thus saves up to 0% of chemical costs over other systems on the market. In comparison with thermal disinfection, up to 0% of the operating costs can be saved. Stable product solution With a chlorine dioxide concentration of g/l (000 ppm), the product solution can be stored for several days. The low concentration makes the solution safe to handle. Integrated measurement value logging device A chlorine dioxide control unit can be easily retrofitted as the connection for a measuring device for chlorine dioxide as well as ph or Redox (measuring cell) is already in place in the system control. Little installtion work Optional accessories simplify assembly and start-up. In fact, the system can be connected and taken into operation without even interrupting the building s water supply. This represents a decisive cost factor when it comes to decontaminating hospitals or nursing homes. Robust design Oxiperm Pro s robust design ensures high operational reliability and lower maintenance costs. Furthermore, the newly designed control system makes for straightforward and user-friendly operation and opens up a number of application areas for discrete disinfection of drinking water installations. Wide field of applications Besides continuous operation, the optional external batch tank allows the use of Oxiperm Pro for shock disinfection or in cleaning applications, such as CIP.
