WebBiofiltration is defined as a filtration process where the filter medium comprises porous material (e.g., sand, granulated active carbon (GAC), or a synthetic carrier material), which is colonized by indigenous microbial communities and where the microorganisms perform at least one of the essential treatment functions of the process. 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. Generally, the biofilm is formed by a community of different microorganisms ( bacteria, fungi, yeast, etc.), macro-organisms ( protozoa, worms, … See more Biofiltration is a pollution control technique using a bioreactor containing living material to capture and biologically degrade pollutants.
