Hi Baboo,
I value your answer, as you tried to explain standard water disinfection treatment. But I have to remind you about the original question wheter there are regulations for water treatment in cooling towers. See Muhammads reply: There are no existing regulations, only recommendations and standards invented by the industry. Due to the fact that legionella pneumophila evaporated from cooling towers caused world wide serious epidemic infections with high mortality rates, officials are seeking for existing regulations or regulations in similar appliacations. Currently in Germany the parliament passes a new regulation, to list all cooling towers by the land registry office and to enforce regular cooling tower water quality, according to standards defined by the German federal environmental office. The standards will be the same as drinking water specs and limited to 1000 KBE or Germ Developing Entities per 1000 ml water. The regulation also froces all responsible operators to control and test the water quality on a regular base, to test the water through certifies labs and to document the test reports. Preventive meassurements or corrective meassurements taken so far are as you mentioned chemical treatments with negtive effects on the equipment or environment. All the standard treatments will not erradicate the biofilms - breeding ground for bakteries and germs. To disinfect cooling towers, you have to use (chorine or chlorine dioxid) continuously, treating symptoms, but never solve the problem. Please see my previous answer. I have listed cooling tower appliactions where we installed our chemical free treatment system. It works permanent and we can proof that we eliminated all biofilm and all tests over years show perfect results of the tested water.
Dont you agree that we have:
1. Regulations and standards in drinking water applications which can be easily applied to cooling tower appliactions
2. Due to the high risk of epedemic infections there is a world wide need for water quality regualtions in cooling towers systems
3. Due to futher negative impact chemical disinfection of cooling towers should be replaced by non chemical treatment processes.
I would be happy to give you further information uppon request.
