SUCCESS STORY: SWEDISH HOSPITAL LEGIONELLA CONTROL

PROJECT BACKGROUND

Uppsala Univeristy Hospital, Sweden

  • Pilot project commissioned by Uppsala Property Operations

  • Purpose was to review performance of Flow-Tech's ability to reduce biofilm and thereby reduce the risk of legionella in hot water lines

  • A secondary purpose was to see if the technology could reduce the need for hot water system flushing

INSTALLATION

Domestic Water System

  • One (1) 6" Flow-Tech unit

  • Domestic water system

  • Hot water lines

RESULTS

Non-detect achieved. Legionella controlled.

  • Existing biofilm removed and future growth prevented

  • Flow-Tech successfully reduced legionella counts across all 17 test sites throughout hospital

    • Some test sites were as far as 350' away from installation

  • Fan Room C2 experienced a reduction in legionella counts from nearly 6,000 CFU/L to less than 1000 CFU/L (non-detect)

"This pilot project is very valuable. Use of the tested technique appears to be a reasonable addition/alternative to treating water for a general purpose to keep bacterial levels down."
