Microbial Community in a Biofilter for Removal of Low Load Nitrobenzene Waste Gas. [PDF]

PLoS ONE, 2017
To improve biofilter performance, the microbial community of a biofilter must be clearly defined. In this study, the performance of a lab-scale polyurethane biofilter for treating waste gas with low loads of nitrobenzene (NB) (< 20 g m-3 h-1) was ...

A Mathematical Model for Removal of VOC’s From Polluted air Utilizing a Biofilter

Chemical Engineering Transactions, 2012
Recently, for the elimination or reduction of volatile organic compounds (VOC’s) biofilters are being utilized more often. Degradation of the VOC’s is made possible upon different packing of immobilized microbes.

Effects of aerated and non-aerated biofilters on effluent water treatment from a small-scale recirculating aquaculture system for Nile tilapia (Oreochromis niloticus L.)

Die Bodenkultur, 2020
Most recirculation aquaculture systems (RAS) use aerated biofilters to maintain suitable water quality for fish production. However, application of non-aerated biofilters may provide opportunities to lower aeration costs, water usage and concentration of
