Water Treatment
Untreated water
All businesses and organisations with public access to their water have a legal duty of care to ensure that a risk assessment is in place to monitor for legionella, a deadly waterborne bacterium. Over time, a biofilm can form in the water which may increase the risk of legionella outbreaks.

One of the highest profile dangers to human health and safety associated with the mechanical plant of commercial buildings is legionellosis, associated with Legionella pneumophilia bacteria. These organisms proliferate in the water storage or network environments.

Aeris sister company Novapharm Research has demonstrated that Legionella bacteria reside in the biofilm present on the surface in water passage ways.

The Aeris Environmental water treatment technology uses a combination of enzymes and biocides to digest the biofilm and eliminate the bulk of micro-organisms in the system. AerisGuard patented anti-microbial technology cleans and removes contaminants from water sources as well as protecting it from recontamination.

What is Biofilm?
A biofilm can be broadly defined as a collection of micro-organisms that have made contact with a surface and between each other secrete sticky polymeric substances that act as a protective shell and source for capturing nutrients like dust that help the biofilm to grow. Micro-organisms commonly go through stages of attachment, growth and dispersal to develop complex structures and relationships that have been described as "slime cities". In fact the biofilm "lifestyle" may well be the most common mode of existence in the natural environment. Biofilms form on many types of surfaces but one of the most common is where water is in contact with a solid surface as the two requirements for biofilm to grow are the presence of micro-organisms and moisture. These conditions exist in an enormous number of situations around the world and include air conditioning heat exchangers, cooling towers and commercial water circuits - such as those found in mines and paper mills.
