WebApr 30, 2024 · Pressure drops directly indicate the clogging situation inside the biofilters with visual data. Increased biomass accumulation indicates high pressure drop. Therefore, in this study, the pressure drops between the import and export of the filter bed were measured to monitor the clogging situation in the biofilter ( Figure 1 ). WebSeveral measures that could limit the clogging of fungal biofilters with fungal biomass were investigated. The introduction of mites helped to control excessive fungal growth and pressure drop. The pressure drop of a perlite/fungi/mites filter of 1 m height, loaded with 200 m3 gas/m3 filter/h stabilised around 130 Pa. Biofilters based on the ...
