Clean Drinking Water For Africa



Water disinfection means the removal, deactivation or killing of pathogenic micro-organisms.
Microorganisms are destroyed or deactivated, resulting in termination of growth and reproduction. Chemical inactivation of microbiological contamination in natural or untreated water is usually one of the final steps to reduce pathogenic microorganisms in drinking/process water. Combinations of water purification steps for example, oxidation, coagulation, settling, disinfection and filtration cause water to be safe after production.


Types of Disinfection

  • Chlorination: Chlorine is used almost universally in the treatment of public drinking water because of its killing power of harmful bacteria and other waterborne, disease causing organisms.
  • Ozone: Kills 99.9 percent of known harmful bacteria and is extremely effective. Ozone can be used in dirty and muddy water.
  • Ultra Violet: UV light has demonstrated efficacy against pathogenic organisms, including those responsible for cholera, polio, typhoid, hepatitis and other bacterial, viral and parasitic diseases.
