  2. Ultraviolet germicidal irradiation - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet_germicidal...

    UV treatment compares favourably with other water disinfection systems in terms of cost, labour and the need for technically trained personnel for operation. Water chlorination treats larger organisms and offers residual disinfection, but these systems are expensive because they need special operator training and a steady supply of a ...

    They are also called point-of-use water treatment systems and field water disinfection techniques. Techniques include heat (including boiling), filtration, activated charcoal adsorption, chemical disinfection (e.g. chlorination , iodine, ozonation , etc.), ultraviolet purification (including sodis ), distillation (including solar distillation ...

  6. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Ultraviolet light (UV) is very effective at inactivating cysts, in low turbidity water. UV light's disinfection effectiveness decreases as turbidity increases, a result of the absorption, scattering, and shadowing caused by the suspended solids. The main disadvantage to the use of UV radiation is that, like ozone treatment, it leaves no ...

  7. Ozonia - Wikipedia

    en.wikipedia.org/wiki/Ozonia

    It is a well-known fact that ozone, a very strong oxidant, is used in water treatment disinfection.. It shows an extensive range of applications; drinking water, wastewater, water disinfection, color removal, micropollutants, pulp & paper bleaching, process water, ballast water, cooling towers, beverage and water bottling, aquaculture, aquariums (zoos), cyanide regeneration, food/ produce ...
