Vuerich R, Martinelli V, Vodret S, Bertani I, Carletti T, Zentilin L, Venturi V, Marcello A, Zacchigna S. A new laser device for ultra-rapid and sustainable aerosol sterilization. Environ Int. 2022 Jun;164:107272. doi: 10.1016/j.envint.2022.107272. Epub 2022 May 2. PMID: 35526297; PMCID: PMC9060718.

  • This study describes a new laser device able to sterilise droplets containing either viruses or bacteria.
  • A new system was developed, mimicking human droplet formation and preserving bacterial and viral viability.
  • This evidenced the efficacy of 10,600 nm laser light to kill two aerosol transmitted human pathogens, Legionella pneumophila and SARS-CoV-2.
  • A minimal exposure time of <15 ms was required for the inactivation of over 99% pathogens in the aerosol; which is a key element in the design of a device that is safe and can be used in preventing inter-individual transmission.
  • This may give an advantage over existing devices, which mainly aim at either purifying incoming air by filtration or sterilising solid surfaces.

Grime Scene

ANNOUNCING OUR NEW GRIME SCENE COMPETITION:

Following on from the successful Grime Scene competition, we have decided to continue the theme for another year, but with a twist. This year, we are asking for photographs of the grimiest pictures you can find accompanied with another photograph of how the ‘scene’ has been improved by your maintenance or cleaning.


We will display the photographs in each of the Waterline editions throughout 2024. The ‘most improved’ picture will be chosen by WMSoc members via an online vote. The winner will receive a £25 Amazon Gift Voucher after the Winter 2024/25 edition has been published.


Please send your photographs to:
waterline@wmsoc.org.uk.

Lovibond MD640 Photometer (PTSA & Fluorescein capable)

Product Spotlight Drop Test Kits

How many times have you heard … ‘we’re not sure what the system volume is’. A common problem which can be expensive - wasting chemical over dosing, or underdosing so the treatment is ineffective (i.e. shock dosing a biocide). The MD640 photometer has PTSA & Fluorescein capability built in. Simply use our System Checkers to add to an unknown system and read a PTSA or Fluorescein levels to accurately identify the system volume.

The Hydrosense PRO range

Hydrosense

The Hydrosense PRO range pioneers Legionella pneumophila detection, the cause of over 97% of Legionnaires’ disease outbreaks, by identifying all the serogroups 1-15 of this dangerous Legionella species. This easy-to-use, highly sensitive test uses unique filtration, offering a three-line test result that distinguishes between serogroup 1 and serogroups 2-15 within 25 minutes. The water test has a level of detection of 100 CFU/L and swab tests detect 200 CFU per swabbed area, providing crucial, rapid insights for water safety management.
