Aqua Disinfect

Aqua Disinfect, a division of Aqua Service, is a service company providing chlorine dioxide generators and CLO2 in solution (Aqua D3000) to solve bacteria problems in a building’s mechanical (process water) and drinking water (potable) systems as well as bacteria problems in many other industries and businesses.

Potable Water Bacteria Control

LEGIONELLA PREVENTION AND CONTROL

In the prevention and control of Legionnaire’s Disease-causing microbes, chlorine dioxide has taken an eminent role. The specific characteristics of the disinfectant make sure ClO2 gets the job done where others fail. Biofilm in the piping can protect Legionella from most of the disinfectants. Chlorine dioxide, however, removes the biofilm and kills the bacteria, spores, and viruses.

Other advantages are:

  1. The bactericidal efficiency is relatively unaffected by pH values between 4 and 10
  2. The required contact time for chlorine dioxide is lower
  3. Chlorine dioxide has better solubility
  4. Chlorine dioxide does not react with ammonia or ammonium
  5. It destroys THM precursors and increases coagulation
  6. ClO2 destroys phenols and has no distinct smell

POTABLE WATER DISINFECTION

Chlorine dioxide has been used for years in potable water disinfection (in the US since 1944). The need arose when it was discovered that chlorine and similar products formed some dangerous DBP’s (disinfection by-products) like THM (trihalomethanes).

Since then, many UK- and US-based water companies have started using chlorine dioxide. There are, however, more reasons to use chlorine dioxide:

  1. The bactericidal efficiency is relatively unaffected by pH values between 4 and 10.
  2. Chlorine dioxide is clearly superior to chlorine in the destruction of spores, bacteria, viruses, and other pathogen organisms on an equal residual base.
  3. The required contact time for chlorine dioxide is lower.
  4. Chlorine dioxide has better solubility.
  5. No corrosion associated with high chlorine concentrations. Reduces long term maintenance costs.
  6. Chlorine dioxide does not react with ammonia or ammonium.
  7. It destroys THM precursors and increases coagulation.
  8. Chlorine dioxide destroys phenols and has no distinct smell.
  9. It is better at removing iron and magnesia compounds than chlorine, especially complex bounds.
