What is bio filteration,explain in details?

Answer 1

Biofiltration is an air treatment process where contaminants and odor causing agents are filtered through a biologically active media. Biofilter media may consist of compost, activated carbon, bulking agents, buffering agents and inorganic additives. The role of the media is twofold, to filter and adsorb contaminants from the air stream and to provide an environment for biological growth. The biology of biofilters is very complex and includes various types of bacteria, fungi and macroscopic life such as worms and nematodes. A healthy biofilter is self-sustaining and includes a balance of organisms.

Since 1978 we have been exporting tropical fish to the American market. Our customers demand healthy, good looking fish at a reasonable price. To do this we must maintain excellent water quality.


We had quite a challenge of trying to maintain excellent water quality. We keep about 20,000 Arius Jordany (a small catfish that comes from brackish waters) in 2000 liters of water. This catfish must be caught in city sewers where they feed all day on waste products and some toxic matter. We catch these fish, then transport them, to clear waters where they must be cleaned and maintained for three weeks until they are ready to export.

Highly sophisticated filtering equipment, where use, and much filtering substrate must be changed periodically, with high expenses, hurting our final price with increasing costs.


We had to find another way to filter the water. In 1995 we started using bacteria as a filter and the results were fantastic! The results of this bacteria bed were so astonishing that we were able to pack 250 fish per box instead of only 80!.

We then began creating the filters for personal aquariums and have had fantastic results here as well. We have aquariums that requires only minimal maintenance.

In our experience during two years period testing we only needed to perform partial water changes when vacuuming debris for the filter bottom. All fish in it are healthy and in perfect conditions, showing to this point no symptoms of distress or sickness. You have to see it to believe it.

Charles Chamberland was a French microbiologist who worked with Louis Pasteur. In 1884 he developed a type of filtration known today as the Chamberland filter or Chamberland-Pasteur filter, constituting of an unglazed porcelain bar. He was also credited for starting a research that led to the invention of the autoclave device.
this is the highest relevance you know.. although i don't see some connection..
