Advantages and disadvantages of biotrickling filters technology [2, 10, 13, 14]

Biotrickling filters
Advantages	Disadvantages
Effective removal of pollutants	Risk of bed blockage by excessively growing biomass increase in a pressure drop in gas phase due to clogging of the bed and the need to remove inhibitors formed as secondary process products
Process conditions: 25-30°C, atmospheric pressure	Low efficiency in removing compounds insoluble in water
Low operating costs - no need for bed replacement and disposal, low energy consumption	Inability to use this technology for non-biodegradable compounds
Very good process control ability
Ecological purity - no secondary pollutants
No risk of explosion

A review of recent work on the effectiveness of biodegradation in relation to packing material [29, 30, 31, 32, 33, 34, 35, 36, 37]

References	Pollution	Packing material	Degradation Effectiveness/Conclusions
Hernandez et al. 2013 [30]	Ethylmercaptan, NH₃ and H₂S	Poplar wood chips and polyurethane foam	Both biotrickling filters achieved complete NH₃ removal, and more than 90% degradation of H₂S, ethylmercaptan reported lower performance in biotrickling filters packed with polyurethane foam. Polyurethane foam requires a longer time for the immobilization of microorganisms, poplar wood shows greater resistance in terms of NH₃ elimination, the durability of poplar wood is 2 years and much more profitable compared to polyurethane foam.
Sun et al. 2019 [31]	H₂S from municipal wastewater treatment plant	Polypropylene rings	The average H₂S removal efficiency was 91.8%
Chen et al. 2019 [32]	H₂S from sewage lift station	Bamboo charcoal	The average H₂S removal efficiency was 99%
Huan et al. 2020 [33]	NH₃ and H₂S	Polyhedral spheres	The average H₂S removal efficiency was 98.25% and NH₃ was 88.55%
Liu et al. 2020 [34]	removal of odors (mainly H₂S and NH₃), from the sludge dewatering room in wastewater treatment plant.	Polyurethane, Volcanic rock, modified activated carbon fiber	Odor (mainly H₂S and NH₃) removal efficiency was 98,5%
Ying et al. 2020 [35]	H₂S and NH₃	Porcelain Raschig rings and ceramsite	The average H₂S and NH₃ removal efficiency was over 99%
Chen et al. 2016 [36]	H₂S	Activated carbonloaded polyurethane (upper layer) and with modified organism-suspended fillers (lower layer)	The average H₂S removal efficiency was greater than 96%In addition, the biotrickling filter was able to withstand periods of contaminated starvation (1.5 days and 7 days) with several hours of recovery time
Lebrero et al. 2021 [29]	H₂S, methylmercaptan and toluene	Conventional plastic packing material and new clay-based materials (Saint Gobain)	The use of new fillings in the biotrickling filter has increased the efficiency and buffer capacity compared to plastic rings. Similar conclusions apply to biofilters, almost complete reduction of H₂S and toluene and 80% methylmercaptan removals were investigated. Clay-based packing materials (Saint Gobain) were found to have high buffer capacity, high water retention and good gas-liquid mass transfer
Tu et al. 2019 [37]	Mixed sulfur compounds	Plastic balls in the upper layer and with lava rocks in the bottom layer	Improvement in sulfur removal efficiency and a higher bed pH using the new packing combination compared to a lava rocks only packing.
