Chlorine Dioxide

Legionella is a genus of bacteria that can cause Legionnaires’ disease, a serious respiratory infection. Legionella bacteria can grow in water systems, including building plumbing systems, cooling towers, and hot tubs.

Chlorine dioxide is a disinfectant that is effective against Legionella bacteria. It is a powerful oxidizer that can penetrate biofilms, which are slimy layers of bacteria that can protect Legionella from other disinfectants.

How Chlorine Dioxide Works

Chlorine dioxide works by oxidizing the cell walls of Legionella bacteria, killing them. It is also effective at removing biofilms, which can harbor and protect Legionella bacteria.

Benefits of Using to Treat Legionella

There are several benefits to this product over other disinfectants for treating Legionella:

  • It is effective against a wide range of microorganisms, including Legionella bacteria.
  • It is effective over a wide pH range.
  • It is effective at penetrating biofilms.
  • It is relatively stable in water.
  • It is non-corrosive to most metals.

Applications for Legionella Control

It can be used to treat Legionella in a variety of water systems, including:

  • Building plumbing systems
  • Cooling towers
  • Hot tubs
  • Industrial water systems
  • Municipal water systems

How to Use to Treat Legionella

it can be generated on-site or purchased as a pre-generated solution. It is typically injected into the water system at a concentration of 0.4-0.7 mg/L. A residual chlorine dioxide concentration of 0.1-0.5 mg/L should be maintained throughout the water system to control Legionella.

Safety Considerations

While a safe disinfectant when used properly, it is important to note that chlorine dioxide is a gas and can be dangerous if inhaled. It is also important to avoid contact with solutions, as they can irritate the skin and eyes.

Here are some additional things to keep in mind when using this solution to treat Legionella:

  • It can react with some chemicals in water to form harmful disinfection byproducts. It is important to have your water tested to ensure that it is compatible with chlorine dioxide use.
  • It can also cause corrosion of some metals, such as copper and brass. If your water system contains these metals, you may need to take additional precautions to prevent corrosion.
  • It is important to monitor the chemical concentration in your water system regularly to ensure that it is at a level that is effective against Legionella but not so high that it causes other problems.

If you are considering using chlorine dioxide to treat Legionella, it is important to consult with a qualified water treatment professional.

Chlorine dioxide is an effective disinfectant for treating Legionella bacteria. It is a good choice for treating Legionella in a variety of water systems, including building plumbing systems, cooling towers, and hot tubs.
