1. General
Oxiperm OCG-166Oxiperm OCG-166 systems generate 0.75 to 10 kg/h of chlorine dioxide directly on site according to the proven sodium chlorite/chlorine process. The produced chlorine dioxide solution in the batch tank has a concentration of 3 g/l.
Safety and convenience• Menu-controlled plain-text operator prompting,
messages for operating state and errors• Saved error messages are always available.• The interaction of precise dosing technology,
perfect mixture of components and almost complete chemical conversion of the sodium chlorite within a short time keeps your costs at a low level permanently.
Technical characteristics• Optional Profibus interface for the connection of
Oxiperm OCG-166 to a PLC or process control system.
• State-of-the-art sensors and precise control electronics provide high precision and process reliability.
ApplicationsUsually, 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.
RemarkLegislation on the use of disinfection products in watertreatment applications is country-specific. Please contact your local Grundfos sales office for further details 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.
