  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 ...

    Low power consumption of semiconductors introduce UV disinfection systems that utilized small solar cells in remote or Third World applications. [ 2 ] By 2019, LEDs made up 41.4% of UV light sales, up from 19.2% in 2014 [ 3 ] The UV-C LED global market is expected to rise from $223m in 2017 to US$991m in 2023.

    In April 2012, Chicago Mayor Rahm Emanuel, former Illinois Governor Pat Quinn, and the U.S. EPA awarded the MWRD $10 million through the Illinois Jobs Now! capital program. That funding supplemented the $21 million in engineering and design costs needed to make the MWRD's disinfection facilities possible.

    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 ...

    The intensity of the UV radiation decreases rapidly with increasing water depth. At a water depth of 10 cm (4 inches) and moderate turbidity of 26 NTU, UV-A radiation is reduced to 50%. PET soft drink bottles are often easily available and thus most practical for the SODIS application. Oxygen

  9. Infection prevention and control - Wikipedia

    en.wikipedia.org/wiki/Infection_prevention_and...

    Disinfection uses liquid chemicals on surfaces and at room temperature to kill disease-causing microorganisms. Ultraviolet light has also been used to disinfect the rooms of patients infected with Clostridioides difficile after discharge. [14] Disinfection is less effective than sterilization because it does not kill bacterial endospores. [15]
