• Far UV-C radiation: An emerging tool for pandemic control

  Critical Reviews in Environmental Science and Technology · 2022 · 173 citations

  1st authorCorresponding

  Far UV-C, informally defined as electromagnetic radiation with wavelengths between 200 and 230 nm, has characteristics that are well-suited to control of airborne pathogens. Specifically, Far UV-C has been shown to be highly effective for inactivation of airborne pathogens; yet this same radiation has minimal potential to cause damage to human skin and eye tissues. Critically, unlike UV-B, Far UV-C radiation does not substantially penetrate the dead cell layer of skin (stratum corneum) and does…

  reviewOpen access

  • The photodecay rate constants of 5 micropollutants at 222 nm are summarized from literature. • Molar absorption coefficients of 8 oxidants, 5 matrix components, and 7 DOM isolates at 222 nm are reported. • UV 222 promotes radical generation better than UV 254 for all known oxidant precursors on a per photon basis. Concerns over human health risks associated with chemical contaminants (micropollutants) in drinking waters are rising due to the increased use of reclaimed water or water supplies i…

  book-chapterOpen access1st authorCorresponding

  The 1st edition of the textbook Biological Wastewater Treatment: Principles, Modelling and Design was published in 2008 and it went on to become IWA Publishing's bestseller to date. In 2020, the 2nd updated and extended edition of the textbook was published because, since 2008, the knowledge and understanding of wastewater treatment had advanced extensively and moved further away from empirically-based approaches to a fundamental first-principles approach based on chemistry, microbiology, physic…
