Roof Gutter Biofilter - Series DRBF
The biofilters of the series DRBF have been specially designed for the odour elimination and corrosion reduction in roof drain pipes. Especially where rain water and waste water are lead to the same dewatering pipes there are often problems with odour and corrosion.
By the stack-effect of the roof drain pipe waste air which is contaminated with hydrogen sulfide and odor comes in contact with the windows of a house and gets inside. This annoying waste air is bad for the health as well; it causes headache and sometimes shortage of breath.
Another problem is that this waste air is causing corrosion at the roof drain pipes which are made for example of copper. The copper pipes first become black inside and during a few months only they can be completely perforated. At that stage they would have to be replaced.
