Periodic operation of biofilters. A concise model and experimental validation

Combined removal of BTEX in air stream by using mixture of sugar cane bagasse, compost and GAC as biofilter media

“…From such precision, important factor such as filter media coverage, thickness and activity can be determined for modelling. The SEM of microbial growth on various types of media before and after experiment has already been shown by some researchers [44,45]. A comparison of the scanning electron microscopic images of sugar cane bagasse before and after experiment is shown in Fig.…”

Biofiltration and kinetic aspects of a biotrickling filter for the removal of paint solvent mixture laden air stream

“…Even though biofilms seem to consist of a homogeneous layer, there is a considerable non-uniformity within biofilms. Several groups of microorganisms are involved in the degradation of air pollutants in biofilters, including bacteria, actinomycetes, and fungi [30].…”

Neural networks as a tool for control and management of a biological reactor for treating hydrogen sulphide

“…Although Deshusses and Johnson [2] proposed an effective and simple protocol to rapidly determine the performance of biofilters, many difficulties arise during continuous operation. Chmiel et al [3] developed a concise model of biofiltration based on a linear driving force concept to portray the transient behaviour of biofilters forthcoming from periodic operation. Several modelling and experimental approaches regarding adverse factors on biofiltration have also been published.…”
