“…This change has been observed and attributed to H 2 S diffusion (Bowker, 1999). Buisman et al (1990) suggested that the presence of sulfide might result in a shift to filamentous organisms in AS such as Beggiatoa and Thiothrix. However the primary group of bacteria that metabolize sulfur compounds also include non-filamentous microorganisms such as those from the genera Thiobacillus, Thiomicrospira and Thiosphaera.…”

A combination of design configurations (tall vs. short aeration tanks and coarse vs. fine air diffusion) was tested at pilot scale for optimum H 2 S removal by activated sludge diffusion (ASD). The effects of H 2 S diffusion on the wastewater treatment performance, in terms of biological oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (SS) and ammonia (NH 3 ) removal, were also evaluated, in eight four-week trials. The results showed that although all combinations of configurations gave 85 − 100% removal of up to 25 ppmv H 2 S, a combination of fine bubble diffusers in tall or short tanks gave the best results with regard to H 2 S removal (94 and 99%, respectively). This suggests that aeration tank height has no impact on H 2 S removal when using fine bubble diffusers. However, tank height was important in the configurations with coarse bubble diffusers, with 85% removal being obtained for a short tank and 99% for a tall tank configuration. The configuration with fine bubble diffusers in short tanks gave best treatment performance (75, 72 and 80% mean removal rates for BOD, COD and NH 3 , respectively, at the highest dosing period, compared with 72, 71 and 68% for the control). A brief suspension in nitrification was observed soon after commencement of ASD of H 2 S in the configuration with fine bubble diffusers in tall tanks and that with coarse bubble diffusers in short tanks. The configuration with fine bubble diffusers in short tanks also gave the best mixed liquor suspended solids (MLSS) maintenance and was therefore chosen for further studies to investigate removal of H 2 S peaks of up to 150 ppmv. These studies showed no effects of H 2 S diffusion on the wastewater treatment performance, when the plant was fully stabilized and the microbial biomass was well acclimated.

“…Completely mixed, continuously fed biological reactors were used,each containing reticulated polyurethane foam particles in a hybrid fixed-film activated sludge configuration, now recognized as a moving bed bioreactor (MBBR). Buisman et al (1990b) showed that the addition of organics to the influent resulted in a negligible effect on sulfide removal, but that excessive organic material may have promoted the growth of Thiothrix spp. Thiothrix spp.…”

“…In biofilters, it has been shown that the presence of hydrogen sulfide has no inhibitory effects on the biodegradation of carbon disulfide, or vice versa (Yang et al, 1994c). Buisman et al (1990b) studied the effects of organic substrates, including acetate and proprionate, on biological sulfide oxidation. During the study, filamentous bacteria consistent with Thiothrix spp.…”

As a result of stormwater input, leachate currently accumulates in three surface impoundments that were filled with waste materials from the production of viscose rayon. The objective of this study was to optimize a biological treatment system that is currently treating a wastewater stream (leachate) containing high levels of reduced sulfur compounds. Due to future remediation activities, the performance of the onsite biological leachate treatment system must be improved to more stably treat the leachate and eventually treat more concentrated leachate for direct discharge to a surface water receiving stream. The performance of a hybrid attached growth system, a completely-mixed flow-through system, and a complete mix activated sludge system were compared. The hypothesis was that a hybrid attached growth system would more efficiently and stably treat both sulfide and carbonaceous chemical oxygen demand (COD) in the wastewater stream than the current onsite system, which is a completely-mixed flow-through biological process, modeled in the laboratory using a 12.5 L Plexiglas completely-mixed flowthrough reactor (CMFT). The hybrid attached growth system was created by using moving bed biofilm reactor (MBBR) technology in a 12.5 L Plexiglas reactor with 30% by volume fill with media. A complete mix activated sludge (CMAS) process was operated to determine the feasibility of treating the leachate in a typical industrial wastewater system. Results showed that there was no significant difference between the effluent qualities from the hybrid attached growth system and a suspended growth flow-through system when operated at steady-state. However, the MBBR showed significant operational improvements over the CMFT, when operated under variable loading rates and conditions (DO and temperature). Liquid phase characteristics and gas phase emissions were measured to evaluate mass balance of sulfide and COD in the system. For normal operation with the HRT between 18 and 36 hours, sulfide was near completely oxidized in the reactors, with less than 2% of the influent sulfide level remaining in the effluent and less than 0.05% of influent sulfide in the gas emissions. Under steady-state conditions, removal of COD was 73±9% in both reactors, and 40-50% of the carbonaceous COD (cCOD) was removed.

“…Undoubtedly, the major innovative development of the Ae micro WT-system lies in its capacity to convert reduced Scompounds into elementary sulfur [31][32][33][34][35][36][37]; the system enables a high rate and low-cost bio-conversion of volatile S-compounds like H 2 S and methanethiol from polluted gases, e.g., from Liquefied petroleum gas (LPG) [38][39][40][41] and from natural gas and/or biogas. The system is effective up to removal capacities of 50 tons H 2 S/day; for higher loads tentatively the well-proven amine/Claus process still looks more attractive [40].…”

Anaerobic processes for treatment of low and high strength wastewaters and solid wastes constitute the core method in the natural biological mineralization (NBM) treatment concept. When adequately combined with the complementary NBM-systems and modern clean water saving practices in wastewater collection and transport, they represent a feasible route to sustainable environmental protection (EP sus ), in essence even towards a more sustainable society. Despite the development and implementation of modern high rate Anaerobic Wastewater Treatment (AnWT-) systems and complementary innovative NBM-processes, the considerable progress made since the seventies in fundamental insights in microbiology, biochemistry and process technology, still numerous challenging improvements in the NBM-field can be realized. This contribution is mainly based on the insights attained from wide ranging literature evaluations and the results of experimental research conducted by numerous PhD students who participated in our group over the last four decades. An attempt is made here to identify major facets on which an improved insight can, and consequently should, be obtained in order to accomplish more optimal operation and design of various types of Anaerobic Degradation (AnDeg-) processes.
