DISINFECTION

Technology that aims for the destruction or inactivation of pathogenic organisms present in water.
Most of these pathogens are destroyed and/or eliminated during physical-chemical water treatment operations such as filtration. However, sometimes a specific disinfection treatment is necessary to ensure proper sanitary protection.
The most common methods of disinfection are:

  • Ozone
  • Ultraviolet
  • Chemical methods: through the use of a chemical disinfectant. Disinfectants must have a residual effect, meaning, they must remain active agents in the water after disinfection to prevent recontamination of the water in water distribution systems. Main types of disinfectants used:
    • Chlorine
    • Fenton
    • Hydrogen peroxide
    • Permanganate

A number of factors must be taken into account when choosing the appropriate disinfection treatment:

  • Type and concentration of microorganisms
  • Germicidal capacity of the disinfectant
  • Water chemistry and temperature

APPLICATIONS

  • Pharmaceutical industry
  • Food industry
  • Potabilization
  • Water reuse
