Highlights

  • Higher temperatures increased biofilm formation on High-Density Polyethylene (HDPE) pipes in a chlorinated drinking water distribution system (DWDS).
  • Material accumulation was accelerated by temperature but this did not effect biofilm strength
  • Temperature triggered changes in the microbiome of the DWDS and changes were more notable in biofilms.
  • Pseudomonas and Fusarium proliferated with temperature increase and have an enhanced capability to promote biofilm development, thus compromising further water quality.
  • Temperature rise increased detection of Mycobacterium in biofilms and favoured presence of M. avium complex in water and biofilm samples.
  • Risks need to be mitigated to prevent the effects of unavoidable climate change

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.
