Chlorine dioxide generators

WATER DISINFECTION Before treated water reaches the customers it must undergo a disinfection process aimed at destruction and deactivation of microorganisms and inhibition of their growth and reproduction. In order to carry out effective disinfection, it is very important to choose the right disinfectant, the optimal dose, as well as to determine the time of contact with water. An effective disinfectant should be characterized primarily by: • high bactericidal and virucidal potency; • ability to protect water from secondary contamination; • no influence on the organoleptic characteristics of...

DISADVANTAGES: • in the initial period of its application excessive dissolution of sediments in the pipelines may occur, therefore the introduction of ClO2 dose must be gradual, well-thought-out and with technological control; •p ossibility of formation of chlorites and chlorates. WHEN TO USE CHLORINE DIOXIDE DISINFECTION? when you want to solve a problem with Legionella and Mycobacterium when you want neutral taste and smell of water when your water has a pH above 7.4 CHLORINE DIOXIDE when you want to use an effective and safe disinfectant when you want to keep your water supply network clean...

HOCl hypochlorous acid This is not the case with chlorine dioxide - unlike chlorine or sodium hypochlorite, its disinfectant properties remain practically unchanged over a wide pH range (from 4 to 10). ClO2- chlorine dioxide Disinfection activity 80 60 Cl2- chlorine gas NaOCl - sodium hypochlorite Another parameter indicating the effective action of chlorine dioxide is CT (C - concentration, T - time), which determines the bactericidal effect of a given disinfectant. This parameter is nothing but the required disinfectant’s concentration in water [mg/l] and the contact time with the disinfected...

METHODS FOR OBTAINING CHLORINE DIOXIDE COMMERCIAL SOLUTION OF ClO2 Similar to sodium hypochlorite, a stabilized solution of chlorine dioxide is available on the market with a concentration of approximately 6 g ClO2/l. Unfortunately, due to its unit cost and shelf life, it can only be used periodically for very small applications. ClO2 PRODUCTION ON SITE Chlorine dioxide can be produced in generators, directly at the point of dosing. The process of disinfectant production is not complicated and consists in proportional mixing of sodium chlorite (7.5%) and hydrochloric acid (9.0%) solutions, their...

SELECTION OF CHLORINE DIOXIDE GENERATOR When selecting a chlorine dioxide generator for drinking water disinfection, the flow rate of the medium and the dose of disinfectant required to achieve optimum sanitary and hygienic water quality must be taken into account. capacity of chlorine dioxide generator [g ClO2/h ]=max media flow [m3/h] x max dose [g/m3] When disinfecting water with chlorine compounds, it is important to know that the chlorine they contain first oxidizes the reduced iron, manganese and hydrogen sulfide compounds present in the water, as well as organic substances, bromides and...
