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:
Technologies
DISINFECTION
- 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
