What is Legionnaires’ Disease?

Legionnaires’ Disease, caused by Legionella pneumophila or other Legionella bacteria, is a type of atypical pneumonia. It’s an example of legionellosis, which is a broader category of illnesses caused by the Legionella bacteria, including Pontiac fever and Pittsburgh pneumonia. Legionnaires’ Disease, however, is the most common disease that manifests from Legionella bacteria in humans

The Legionella Bacteria

The Legionella bacteria often spreads through water or water systems, as it very rarely spreads from human-to-human contact. The bacteria grows naturally in freshwater, but can spread through man-made water systems of hot tubs, decorative fountains, swimming pools, hot water tanks, cooling towers, and hospital water systems. Biofilm build-up in water systems permits for the Legionella bacteria to grow, and it sloughs off into the water system’s circulation. The infections can occur at any time of year, but often seem to peak in frequency in the fall months

Those with Legionnaires’ Disease are likely to start seeing symptoms two to ten days after being infected with Legionella bacteria. The preliminary symptoms to develop in most patients are a headache, muscle aches, and a fever. As the infection progresses, other symptoms might pop up, including a cough, mucus buildup, a shortness of breath, chest pain, gastrointestinal distress (i.e. vomiting, nausea, and diarrhea), and mental confusion. While these symptoms alone can be caused by a number of other infections that could go away on their own, if an individual suspects any exposure to Legionella bacteria, it’s best to seek medical treatment as soon as possible

A medical professional will likely prescribe a course of antibiotics, along with other treatments, to shorten the recovery period and ensure that complications don’t develop. This is important for anyone, but especially those at a heightened risk of complications in a lung infection like Legionnaires’ Disease, such as the elderly, the immunocompromised, and frequent smokers

How Does Chlorine Dioxide Combat Legionella and Legionnaires’ Disease?

Chlorine dioxide is an oxidizing biocide composed of chlorine and oxygen, which has been proven effective in eliminating Legionella bacteria in cooling towers and hospital water systems. The compound works by eliminating the bacteria at the source, thus preventing its spread to humans. Chlorine dioxide works to eliminate the bacteria at its source, and it inhibits biofilm to prevent growth of Legionella and the eventual contraction of legionellosis among individuals breathing in air with infected droplets

The United States Centers for Disease Control and Prevention (CDC) states that 9 out of 10 CDC investigations show that almost all outbreaks of Legionnaires’ Disease were caused by problems preventable with more effective water management. The United Kingdom Government Health and Safety Executive (HSE) also mentions on its website that Chlorine Dioxide is effective as a control method to assist reductions in the occurance of Legionaire’s disease and controls against outbreak in the workplace. Thus, any large-sized building owner or operator looking to prevent a Legionnaires’ Disease outbreak at their facility should invest in proper maintenance of their water treatment systems. Using chlorine dioxide for regular preventative treatment is one way to prevent the spread of Legionnaires’

Frequently Asked Questions

  1. Why is chlorine dioxide used in water treatment?
    Chlorine dioxide (ClO2) is used in water treatment because it is an effective oxidant, biocide, and disinfectant at relatively low concentrations. It also has minimal reactivity with organic matter and minimal byproducts are formed during the treatment process. Chlorine dioxide can kill bacteria, viruses, and other microbes in water that will help prevent the spread of waterborne diseases without hydrolyzing. Chlorine dioxide will stay as a dissolved gas in a solution, is around ten times more soluble than chlorine, and can be removed by aeration. This potency, combined with safety, makes it an appealing option for water treatment use
  2. When is chlorine dioxide the preferred choice for disinfection?
    ClO2 is a disinfectant, best utilized in systems with surface germs and biofilms. Chlorine dioxide removes biofilms and inactivates germs by destroying cell walls. Furthermore, the oxidation and disinfection capabilities of ClO2 are independent of the pH of the water across a wide range. ClO2 can be used effectively in water with a pH 6 to 9
  3. Is chlorine dioxide safe for water treatment?
    Chlorine dioxide is a safe form of water treatment. It is used in various applications, including the treatment of drinking water for human consumption. The Environmental Protection Agency (EPA) set the maximum allowed concentration of chlorine dioxide in drinking water at no more than 0.8 parts per million (ppm). The Occupational Safety and Health Administration (OSHA), an agency of the United States Department of Labor, has an 8-hour exposure limit of 0.1 ppm in air (0.3 mg/m3) for people in contact with chlorine dioxide. The EU DWGL 98/83 sets the limit for chlorine dioxide application as low as 0.2 ppm. Due to this low addition ratio, the DBP levels are 0.2 ppm for chlorite and 0.25 ppm for chlorate being on a very low level
  4. What is the difference between ClO2 and chlorine?
    Chlorine dioxide (ClO2) is a compound, composed of a chlorine atom and two oxygen atoms. Chlorine and chlorine dioxide are both oxidizing agents, meaning they remove electrons from other compounds during chemical reactions. But whereas chlorine has the capacity to take in two electrons, chlorine dioxide has the capacity to absorb five in highly acidic environments. In a neutral ambient, as in swimming pools and drinking water, ClO2 takes only one electron. In addition, chlorine dioxide does not react with many organic compounds, meaning it does not create chlorinated organics, which can be environmentally dangerous
  5. Is ClO2 corrosive?
    When used at the concentrations required for disinfection without accumulation e.g., in loops, chlorine dioxide is minimally corrosive. Chlorine dioxide is approximately ten times more soluble in water than chlorine and safe methods for chlorine dioxide production have been developed, meaning the corrosive effects of using chlorine dioxide for treatment are minimal
  6. Can ClO2 contribute to reducing biofilms in pipelines?
    ClO2 removes biofilms and keeps them under control. Through this, it helps to reduce steel corrosion in an indirect way.
  7. How reactive and efficient is ClO2?
    Chlorine dioxide is known as an effective water treatment method because of its oxidation capacity at low levels. The predominant effect is the enrichment of dissolved gaseous chlorine dioxide at boundary where microorganisms find their ideal conditions for survival. The high efficiency of chlorine dioxide at low concentrations versus other disinfectants can be seen when comparing its c x t – numbers with other chlorine species.
  8. How is ClO2 produced?
    For water treatment purposes, chlorine dioxide is usually prepared on-site, using methods that produce solutions without a gaseous stage. There are five common methods of production:
    1 – The sodium chlorite or the sodium chlorite–hypochlorite method:
    2 NaClO2 + 2 HCl + NaOCl → 2 ClO2 + 3 NaCl + H2O
    2 – The sodium chlorite–hydrochloric acid method:
    5 NaClO2 + 4 HCl → 5 NaCl + 4 ClO2 + 2 H2O
    3 – The chlorite–sulfuric acid method:
    4 ClO−2 + 2 H2SO4 → 2 ClO2 + HClO3 + 2 SO2−4 + H2O + HCl
    4 – The chlorite persulfate method:
    2 NaClO2 + Na2S2O8 → 2 ClO2 + 2 Na2SO4
    5 – The sodium chlorite – citric acid method:The concentration of chlorine dioxide produced by these methods varies between 1 and 3 g/L. Whereas methods a., b., and c. are used for the disinfection of municipal drinking water, method d. is limited to the disinfection of mains and tanks as it requires highly extended exposure time for complete conversion of the precursors into chlorine dioxide
  9. Is ClO2 expensive?
    Depending on the cost of the precursors that are used to produce chlorine dioxide, for example the Acid Chlorite vs. Chlorine Chlorite process when compared to chlorine, it’s between five and ten times more expensive. The efficacy of ClO2 for biofilm control makes it attractive for operators.
  10. Is ClO2 toxic and can it be stored safely?
    Chlorine dioxide cannot be stored as a gas because at concentrations over 10%, or under pressure, there is a risk of explosion by self-decomposition. If stored for extended periods of time, chlorine dioxide will mainly form the intermediate byproduct chlorite, finally ending in chlorate. A dissociation into chlorine and oxygen only occurs in the gas phase. For these reasons, chlorine dioxide is stored as a solution at concentrations of around 0.3 % ClO2 (3 g/L) and kept away from light and heat. Under these conditions, chlorine dioxide is stable and soluble.
  11. Can I produce my own ClO2 in the facility?
    Chlorine dioxide is usually made on site using one of the production methods mentioned in Question 8, or by using a generation system provided by suppliers
  12. Does the use of ClO2 affect the environment?
    Chlorine dioxide is considered hazardous to the environment. However, chlorine dioxide does not last long in air, water, or soil environments – up to minutes in air and up to hours in water or soil. Due to its reactivity, chlorine dioxide photolyzes rapidly in the atmosphere. It has a tropospheric half-life of just a few seconds and will breakdown rapidly in natural waters or waters that contain a moderate level of organic matter. Chlorine dioxide is converted to the intermediate product chlorite and the final product chlorate. Chlorate levels can be minimized with proper use of ClO2 – refer to Question 15.
  13. Which are the most common applications using ClO2 for water disinfection?
    The most common applications of CIO2 in water treatment are potable water, swimming pools & water parks, food and beverage processing, cooling towers, utility water and wastewater.
  14. How efficient is ClO2 compared with Chlorine, Hypochlorite’s, and Ozone?
    ClO2 is a relatively mild oxidant with a low ORP value in comparison to hypochlorous acid. It oxidizes to generate chlorinated DBP, including THM, as chlorine and hypochlorites do. In addition, it has an excellent residual effect in purified water whereas ozone is depleted by self-decomposition. Once ozone has vanished, the regrowth of germs accelerates, which doesn’t happen with chlorine dioxide.
  15. How do I solve the chlorate issues of ClO2 application?
    When ClO2 interacts with water ingredients and decomposes in feedstock solutions, chlorate is generated. The chlorate formation can be minimized by accurate selection of the generation process (batch or inline) and design of the system — the size of the generator, size of the dosing system, and size of the batch tank. Chlorine dioxide has been proven as a powerful disinfectant and oxidizing agent that works at lower residual levels than other common disinfectants. With a low reactivity to organic compounds, CLO2 also minimizes chlorinated organics in the treatment process, meaning it may be the optimum choice for cooling tower treatment.
  16. When is the chlorite – chlorine process preferred?
    The chlorine-chlorite process is 20 % more effective than the chlorite/acid process when considering the chemistry of generation – see Question 8 reaction A and B. Furthermore, sodium chlorite and hydrochloric acid are expensive chemicals. It is recommended to use the most economic chlorite – chlorine generation process for large-scale applications such as cooling water loops and large-scale drinking water treatment systems.
  17. Is it not better to use ClO2 from one single precursor?
    There is no system available that provides ClO2 in a definite concentration and quantity from one (generally the precursor is sodium chlorite and sometimes sodium chlorate). But each of these precursors requires being activated and transferred to form ClO2 by acidification or by oxidation usually with chlorine.
