Legionella Prevention During Lockdown

8 Permanent Solutions to Prevent Legionella

Article 3 of 3

During these challenging times, many buildings are currently not in use such as offices, schools, museums, sports centres, and holiday parks. Water services that have low use and stagnant areas have an increased potential risk for Legionella growth. On the other hand, hospitals, nursing homes, and residential care are in operation and are 100% focused on the health and care of their patients. In both situations (lockdown or not lockdown building) extra precautions must be undertaken to protect their exposure to Legionella bacteria.

In last week's article we provided 7 helpful tips to prevent Legionella.

In article 3 of 3, we provide 8 permanent solutions for buildings and factories to prevent Legionella.

Legionella Bacteria in London

Water is used in various ways in today's factories and offices, and each use should be risk assessed as advocated by the local authorities. An easy tip to prevent Legionella is 'enhanced flushing'. This should be introduced on the floors and areas that have become vacant or empty, so effectively adding additional outlets to the little used outlet list which are then covered by the existing weekly flushing regime.

NIJHUIS DEBA - Permanent Legionella Prevention Solutions

Depending on the outcomes of the Risk Assessment report, a permanent NIJHUIS DEBA Legionella compliance and control solution can be installed. This includes 24/7 monitoring for cooling towers and cold / hot water services. Below you find 8 possible permanent solutions.

Depending on the situation, a solution can consist of silver stabilised hydrogen peroxide, chlorine dioxide, ozone, electrodeposition, metal ionization, UV filtration system, a patented environmentally friendly bio organic catalyst solution for control of biofilms and online monitoring.
