This system along with other 'patent' systems like electrolysing silver
salts into the liquid will work to a limited extent but will only affect the
'mobile' liquid, they won't get at the bugs living in the slime. As soon as
the system stops circulating, these bugs start to multiply again. These
methods are OK for systems which never get switched off but leave them off
for a week while you go away on holiday and you have a potential problem
when you first switch on again. One of the air conditioning systems I used
to manage was once targetted as being a possible source of a local
Legionnaires disease outbreak and so I had to rapidly become and 'expert
microbiologist' on this subject to be able to counter claims. Fortunately it
wasn't my system which had caused the problem, it was a bus washing system
where the people worked but, because my people hadn't kept their paperwork
right up to date, I had some very trying weeks while the Health and Safety
Executive inquisition probed every corner of every system we had in place!
