“…In addition, the packing material can be irrigated even in the shutdown periods. Baltr ėnas et al [42] designed the BF with packing material consisting of several plates arranged vertically next to each other (Figure 4). To irrigate the packing material, the lower part of the packing material was immersed in a nutrient solution.…”

“…The use of such an irrigation system helped to avoid an insufficient or excess moisture level in the packing material. In addition, the use of a capillary system to irrigate the packing material helped to avoid possible leaching of biomass from the packing material [42].…”

“…This can result in its clogging and increase in the pressure drop. To solve this issue Baltr ėnas et al [42] designed BFs with packing materials consisting of several plates with millimetre gaps between them (Figure 4). In such a plate-type biofilter, air can flow more smoothly and distribute more evenly over the entire volume of the packing material [42].…”

Biofilters (BFs) and biotrickling filters (BTFs) are two types of bioreactors used for treatment of volatile organic compounds (VOCs). Both BFs and BTFs use packing materials in which various microorganisms are immobilised. The water phase in BFs is stationary and used to maintain the humidity of packing materials, while BTFs have a mobile liquid phase. Optimisation of irrigation of packing materials is crucial for effective performance of BFs and BTFs. A literature review is presented on the influence of water content of packing materials on the biofiltration efficiency of various pollutants. Different configurations of BFs and BTFs and their influence on moisture distribution in packing materials were discussed. The review also presents various packing materials and their irrigation control strategies applied in recent biofiltration studies. The sources of this review included recent research articles from scientific journals and several review articles discussing BFs and BTFs.

“…Volatile organic compound (VOC) emissions to the atmosphere are one of the most important environmental problems [1]. Nowadays, biofilters are being increasingly used for mitigation of contaminants such as butanol, toluene, xylene and other VOC from air [2][3][4][5][6]. VOC emissions often have an unpleasant odor.…”

Effect of Packing Material Composition on the Aerodynamic Processes in a Wavy Lamellar Plate-Type Biofilter

2021

Reducing the pressure drop in biofilters is important for the reduction of the energy consumption of these devices. Usually, the pressure drop increases with time due to the biomass growth within the packing material. The aim of this study was to evaluate the aerodynamic processes in a laboratory-scale wavy lamellar (WL) plate-type biofilter equipped with a capillary system for humidifying the packing material. The packing material of a designed biofilter consisted of wavy polymer plates (WPP) vertically arranged next to each other. The pattern of arrangement of the plates allowed sufficiently large spaces, and therefore, the use of such structure had an impact on a decrease in the pressure drop of the biofilter. WPP were coated with three different kinds of materials, namely (I) wood fiber (WF), (II) non-woven caulking material (NWCM) and WF, and (III) linen material (LM) and WF. The results showed that the composition of the packing material influenced pressure drop of the biofilter. The packing material, which consisted of WPP covered with WF, had the lowest pressure drop compared with the other two packing material compositions. In this study, the experimental results were also compared with the results of the performed mathematical modeling of airflow movement.
