Emission of microorganisms from biofilters [PDF]

Bioprocess Engineering, 1991
Experiments are reported on the discharge of microbial germs by biofilter systems used for the treatment of waste gases containing volatile organic compounds. The systems investigated concern six full-scale filter installations located in the Netherlands in several branches of industry, as well as a laboratory-scale installation used for modelling the ...

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.

Nitrogen uptake and internal recycling in Zostera marina exposed to oyster farming: eelgrass potential as a natural biofilter [PDF]

, 2016
Oyster farming in estuaries and coastal lagoons frequently overlaps with the distribution of seagrass meadows, yet there are few studies on how this aquaculture practice affects seagrass physiology.

Fouling-resistant biofilter of an anaerobic electrochemical membrane reactor

Nature Communications, 2019
Membrane fouling is a considerable challenge for the stable operation of anaerobic membrane-based bioreactors. Membrane used as a cathode is a common measure to retard fouling growth in anaerobic electrochemical membrane bioreactors (AnEMBR), which ...

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
