“…In order to evacuate hydrogen sulfide from wastewater treated for the AD process, physicochemical processes such as absorption have been used [ 112 , 113 ], scrubbing [ 114 ], and using water-containing chemicals [ 115 , 116 ]. Nonetheless, these procedures are expensive and can result in chemical waste accumulation.…”

“…On the other hand, Kang et al [30] showed that sulfide oxidation decreases the pH values in the liquid phase. The latter agrees with our experimental results, since the main pH value in the reactor with zeolite (7.55) was lower than the system without zeolite (7.72).…”

This work aimed to achieve partial nitrification (PN) in a Sequencing Moving Bed Biofilm Reactor SMBBR with zeolite as a biomass carrier by using sulfide pulses in the presence of organic matter as an inhibitor. Two conditions were evaluated: sulfide (HS−) = 5 mg S/L and vvm (air volume per liquid volume per minute, L of air L−1 of liquid min−1) = 0.1 (condition 1); and a HS− = 10 mg S/L and a vvm = 0.5 (condition 2). The simultaneous effect of organic matter and sulfide was evaluated at a Chemical Oxygen Demand (COD) = 350 mg/L and HS− = 5 mg S/L, with a vvm = 0.5. As a result, using the sulfide pulse improved the nitrite accumulation in both systems. However, Total Ammonia Nitrogen (TAN) oxidation in both processes decreased by up to 60%. The simultaneous presence of COD and sulfide significantly reduced the TAN and nitrite oxidation, with a COD removal yield of 80% and sulfide oxidation close to 20%. Thus, the use of a sulfide pulse enabled PN in a SMBBR with zeolite. Organic matter, together with the sulfide pulse, almost completely inhibited the nitrification process despite using zeolite.

“…Numerous physicochemical procedures have been in use to eradicate H 2 S from industrial waste gas streams such as absorption (Boumnijel et al, 2016;Taheri et al, 2016), scrubbing , and using chemicals that are water-containing (Kang et al, 2020;. Nonetheless, these operational procedures are costly and induce the production of chemical wastes.…”

The performance of experimental batch-reactor loaded with slaughterhouse waste at mesophilic temperature was investigated as well as the inhibition of both ammonia and sulfide in the aqueous phase during phase I of anaerobic digestion. The methylene blue method was used to quantify the amount of sulfide in the liquid phase whereby the amount of total ammonia nitrogen in the liquid phase was quantified by using Nessler method. The maximum CH 4 content of 69.6% was achieved at 0.37 VFA/Alkalinity ratio and pH of 7.51 during day 37 of anaerobic digestion. However, a sudden increase of ammonia nitrogen in the digester from day 44 to day 68 decreased the methane content by 62.15% from 65% to 24.6%. During phase II of anaerobic digestion, the efficacy of inorganic additives on the removal of total ammonia nitrogen and sulfide in the aqueous phase of slaughterhouse waste undergoing anaerobic digestion in the batch reactor was investigated for 65 days. A mixture of natural inorganic additives processed from the anthill and red rock soil samples collected from Arusha, Tanzania were used as adsorbents in different ratios. XRD analysis revealed that the anthill soil sample is endowed with quartz and hematite major mineral phases while red rock soil contains albite, pyroxene, and quartz as predominant phases. The anthill and red rock soil samples calcined at 900 ℃ displayed higher BET surface areas of 815. 35 and 852.35 m 2 /g, respectively. Among all the adsorbent ratios investigated at different calcination temperatures, the ratio of 1:1 and calcination temperature of 700℃ produced the highest adsorption capacities of both TAN and sulfide. Adsorption isotherm studies revealed that Jovanovich model fitted better to the experimental data than Langmuir and Freundlich models. The findings of this study have demonstrated that anthill and red rock soils can be exploited as affordable, ecofriendly and efficient adsorbents for mitigation of TAN and sulfide from the liquid phase and sustenance of methanogenesis.
