“…The H 2 S removal performance of the HFMBs (∼ 100% RE with an EC of 17.0 g m −3 h −1 ) was similar to that of the steady-state performance of the BTFs reported by Watsuntorn et al 40 and Khanongnuch et al, 9 and it was better than a hybrid membrane bioscrubber (MBS), where the MBS fabricated with a PDMS tubular membrane (non-porous, dense, and hydrophobic in nature) achieved ∼80% RE with a maximum EC of ∼8.0 g m −3 h −1 . 22 However, similar (∼ 20 g m −3 h −1 ) 42 or higher (∼ 85 g m −3 h −1 ) 43 ECs have also been reported for the BTF system, even with a lower EBRT (∼ 30-60 s). Comparatively, a longer gas contact time (EBRT of 187 s) has been chosen in this feasibility study of the HFMB to allow adequate time to the functional microorganisms for the H 2 S bioconversion, and to test the HFMB performance in the absence of possible limiting factors, such as a shorter gas contact time (e.g., 40 s) 44 that can affect the H 2 S mass-transfer and removal performance.…”

BACKGROUND Hydrogen sulphide (H2S) must be treated at its emission source to avoid health risks, odour, and corrosion. Conventional physico‐chemical H2S removal technologies (for example, membrane contactors or chemical scrubbers) have several limitations, such as requiring high amounts of absorption chemicals and energy. In contrast, biological H2S removal technologies are environment friendly, easy to operate, and less expensive due to their low energy requirements. In this study, the feasibility of a porous hydrophilic polyethersulfone hollow fibre membrane bioreactor (HFMB) was tested for the biological removal of gas‐phase H2S by employing three lab‐scale reactors (two biotic and one abiotic). The HFMBs were operated at ~20 °C for ~3 months, employing different H2S inlet loading rates (ILR) and an empty bed residence time of 187 s. RESULTS Biotic performance of the HFMBs demonstrated that the removal efficiency (RE) varied between the different inocula and was in the range of 80–100% for the applied H2S ILR of ~5.0–7.5 g m−3 h−1. The RE reached a constant value of ~100% in both biotic reactors at an ILR of ~17.0 g m−3 h−1 when using acclimatized inoculum. The biotic HFMBs demonstrated ~5–9 times higher H2S flux and ~ 20–26 times higher mass transfer compared to the abiotic control. Surface morphology revealed attached microbial growth on the outer surface of the membranes, while the high throughput sequencing confirmed the richness of H2S oxidizing microbial communities on the shell side. CONCLUSION The obtained results confirm that the HFMB configuration is suitable for biological treatment of H2S laden waste gas. © 2021 Society of Chemical Industry (SCI).

“…B1, B. licheniformis and B2.2.2 had a strong ability to remove hydrogen sulfide gas in comparison with the control treatment, and there were significant differences with the control treatment (p < 0.05). The highest removal rate of B. licheniformis was 99.29%, which greatly reduced the concentration of hydrogen sulfide gas, and was about 8% higher than the deodorization device designed by Huang et al [22]. The removal rate of hydrogen sulfide gas by P. denitrificans was also above 80%, but there was no significant difference with that of the control treatment (p > 0.05).…”

Human living environments and health are seriously affected by the odor produced from fermentation of livestock and poultry manure. In order to reduce the odor pollution caused by livestock and poultry manure, efficient strains were screened and two methods were tried in this study. The orthogonal test design was used to analyze the gas produced by pig manure under different conditions of temperature, time, wheat straw doping amount and calcium carbonate doping amount. Then, according to ammonia, hydrogen sulfide and comprehensive odor removal effects, the high efficiency of deodorizing strains were screened. The results showed that pig manure produced the least odor when the temperature was 20 °C, added 0% calcium carbonate, 20% wheat straw and waited for 48 h. Three strains were screened to inhibit the odor production of pig manure: Paracoccus denitrificans, Bacillus licheniformis and Saccharomyces cerevisiae, showed that their highest removal rate of ammonia and hydrogen sulfide gas could reach 96.58% and 99.74% among them; while for three strains of end-control pig manure stench: Pichia kudriavzevii, P. denitrificans and Bacillus subtilis, the highest removal rate of ammonia and hydrogen sulfide gas reached 85.91% and 90.80% among them. This research provides bacteria resources as the high-efficiency deodorizing function for the source suppression and the end treatment of the odor gas of pig manure, which has high application value for the control of odor pollution.

“…The presence of polyhedral spheres in biotrickling filters had shown simultaneous removal of hydrogen sulfide and ammonia with efficient compost deodorization. The theoretical evaluation was done to identify the microbial community engaged in the degradation of pollutants [ 119 ]. However, the microbial metabolism pathway had required a deep insight to expand the technique from lab or pilot scale to application scale.…”

A review on biofiltration techniques: recent advancements in the removal of volatile organic compounds and heavy metals in the treatment of polluted water

Good quality of water determines the healthy life of living beings on this earth. The cleanliness of water was interrupted by the pollutants emerging out of several human activities. Industrialization, urbanization, heavy population, and improper disposal of wastes are found to be the major reasons for the contamination of water. Globally, the inclusion of volatile organic compounds (VOCs) and heavy metals released by manufacturing industries, pharmaceuticals, and petrochemical processes have created environmental issues. The toxic nature of these pollutants has led researchers, scientists, and industries to exhibit concern toward the complete eradication of them. In this scenario, the development of wastewater treatment methodologies at low cost and in an eco-friendly way had gained importance at the international level. Recently, bio-based technologies were considered for environmental remedies. Biofiltration-based works have shown a significant result for the removal of volatile organic compounds and heavy metals in the treatment of wastewater. This was done with several biological sources such as bacteria, fungi, algae, plants, yeasts, etc. The biofiltration technique is cost-effective, simple, biocompatible, sustainable, and eco-friendly compared to conventional techniques. This review article provides deep insight into biofiltration technologies engaged in the removal of volatile organic compounds and heavy metals in the wastewater treatment process.
