How is drinking water purified?

The two most common methods to kill microorganisms in the water supply are -

  • Oxidation with chemicals such as chlorine or ozone

What is water disinfections?

Water is disinfected to kill any pathogens that may be present in the water supply and to prevent them from growing again in the distribution systems, without disinfections, the risk from waterborne disease is increased.

Disinfections has both advantages and disadvantages.

Disinfections is used to prevent the growth of pathogenic organisms and to protect public health and the choice of the disinfect depends upon the individual water quality and water supply system.

The key factors in selecting a disinfections system depend upon:

  • Its effectiveness in killing a range of microorganisms.
  • Possibility of producing harmful disinfections by-products.
  • Residual effect - the ability of disinfections agent to remain effective in the water throughout the distribution system.
  • Safety and easy handling of chemicals and equipments.
  • Cost effectiveness.
