Circular Stand-Alone Biofilter - Series SRBF
The Bioteg Circular Stand-Alone Biofilter with its compact design and long service life can be applied to solve a variety of different odor problems. Among our customers for the SRBF-Series are waste water treatment plants (WWTP), landfills and sewage storage systems as well as the food and chemical industry. They are designed to treat airstreams from 20 to 500 m3/h. To adapt to higher airstreams (of up to 2,000 m3/h) our Circular Stand-Alone Biofilters can be run in a two to four filter network.
These filters can be used as inexpensive passive biofilters and are readily upgradable to active biofilters at any time by the addition of a cover and a fan. A controlled surface irrigation system is optional.
Depending on the evnvironmental conditions, the biofilter material may last up to 7 years. The replacement of the filter material is an easy and inexpensive process. The used biofilter material can be readily composted.
