Biofilter - Wikipedia
A biofilter is a bed of media on which microorganisms attach and grow to form a biological layer called biofilm. Biofiltration is thus usually referred to as a fixed–film process.
Biofilter - an overview | ScienceDirect Topics
A biofilter is a mixture of wood chips and compost, which supports a good volume of microorganisms. The contaminated air is forced into this material which is ultimately converted into carbon dioxide and water with the help of microbes. To develop a successful biofilter, a proper and appropriate selection of biofilter media is needed.
Biofiltration as a treatment technology in water and ...
Biofilters contain filter medium grains (e.g., sand, granular activated carbon) that are covered with biofilms. The biofilm activities break down nutrients (e.g., nitrogen and phosphorous ...
Biofiltration: A modern technology for wastewater treatment
2022年1月1日 · Biofilters for the treatment of wastewater are a type of submerged biofilm reactor. It is generally necessary to remove nonactive biofilm and or detached biofilm, in order to maintain a good bioactivity of the biomass in the biofilters, and prevent the media bed from clogging.
Biofiltration - an overview | ScienceDirect Topics
The biofilter is a filter in which on the surface of the filter material develops biological films (biofilms) consisting of bacteria which feed with certain pollutants from the water.
