Oxiperm OCD-164 1 1. General Oxiperm OCD-164 Oxiperm OCD-164 uses diluted 9 % HCl solution and 7.5 % NaClO 2 solution to generate 30 to 2000 g/h of chlorine dioxide. Precision and process stability High efficiency and user-friendly ergonomics State-of-the-art sensors and electronics as well as unique calibration technology provide high precision and process reliability. The interaction of precise dosing technology, perfect mixture of components and complete chemical reaction within a short time keep your costs at a low level permanently. Dual control LEDs in a clearly arranged flow scheme allow possible errors to be identified quickly and precisely. In addition, all operating states and messages are shown in the plain-text display. Compact design and function All components that require regular maintenance are very easy to access. Remote communication Optionally, Oxiperm OCD-164 can be connected to higher-level integration systems and process control systems via bus interface. 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 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. Remark Legislation on the use of disinfection products in water treatment applications is country-specific. Please contact your local Grundfos sales office for further details on the on the use of our products in your application and area. No chance for pathogens Legionella are rod-shaped bacteria that enter drinking water systems and start to reproduce. Especially in temperatures between +30 C and +40 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 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, such as constructional modifications.
