The Titanium AOP leaves no residual by-products behind. In addition, it not only breaks down Legionella bacteria, but also E. coli, Pseudomonas aeruginosa, fungi and all other micro-organisms, but also decomposes any resultant matter, both organic or microbiological. The decomposition of all matter within the AOP system helps prevent biofilms developing as they are starved of the nutrients they require to multiply.
The payback period on the Titanium AOP depends on what sort of methods you are currently using to prevent Legionella. You will save the cost of having to raise the water temperatures at regular intervals and then flush through the system. You will also save the cost and environmental impact from no longer needing to purchase chemicals on a regular basis.
In a recent long term test undertaken in Southern Europe the AOP system was fitted on the cooling towers of a large hospital. Prior to this a cocktail of biocide chemicals had been used; all of which had failed to keep bacterial counts low. Environmental conditions at the site were very difficult and included hard water, elevated temperatures, air pollution and high levels of dust. However after only 2 weeks with the AOP in operation the chemical biocide dosing was stopped and bacterial counts were reduced by 99% compared to when the biocide treatment system had been used.
