“…For T. thioparus, an EC of 14.9 g H2S-S /m 3 /h was obtained in a similar biotrickling filter (Ramírez et al, 2009a). A similar performance was observed by Aroca et al (2007) using polyethylene rings as the carrier.…”

a b s t r a c tThe present work aims to use a two-stage biotrickling filters for simultaneous treatment of hydrogen sulphide (H 2 S), methyl mercaptan (MM), dimethyl sulphide (DMS) and dimethyl disulphide (DMDS). The first biofilter was inoculated with Acidithiobacillus thiooxidans (BAT) and the second one with Thiobacillus thioparus (BTT). For separate feeds of reduced sulphur compounds (RSC), the elimination capacity (EC) order was DMDS > DMS > MM. The EC values were 9.8 g MM-S /m 3 /h (BTT; 78% removal efficiency (RE); empty bed residence time (EBRT) 58 s), 36 g DMDS-S /m 3 /h (BTT; 94.4% RE; EBRT 76 s) and 57.5 g H2S-S /m 3 /h (BAT; 92% RE; EBRT 59 s). For the simultaneous removal of RSC in BTT, an increase in the H 2 S concentration from 23 to 293 ppmv (EBRT of 59 s) inhibited the RE of DMS (97-84% RE), DMDS (86-76% RE) and MM (83-67% RE). In the two-stage biofiltration, the RE did not decrease on increasing the H 2 S concentration from 75 to 432 ppmv.

“…The minimum time between each inlet concentration value was 6 h. Ramírez et al (2009a) reported that the steady-state on working with T. thioparus for H 2 S removal was reached after 40 times the EBRT. The total durations of the Experiments were 5 and 8 days for MM and DMDS, respectively.…”

This paper focuses on the study the possibility of phosphogypsum utilization in the biotechnological processes for hydrogen sulfide removal from biogas. The optimal parameters of the process of granulation dihydrate phosphogypsum were determined. The biochemical characteristics of granular carrier based on phosphogypsum was studied. The efficiency of the gas cleaning under immobilization of the thiobacillus on the surface support medium was analyzed. The main parameters of the gas cleaning process were determined. The degree of H 2 S removal from a gas stream was 98.22% at pH = 5.0 and optimum empty bed residence time of 10 h. The possibility of the phosphogypsum using as a new type of mineral support medium for the associations of sulfur-oxidizing microorganisms developing was determined in the process of biological gases purification from sulfur compounds. It was the first time both theoretically and experimentally proved that the mineral support on the basis of phosphogypsum has a sufficient micro and macro elements that necessary for the thiobacteria development. Thus it is eliminating the need to supply additional sources of feeding organisms to biofilter. The gas purification biotechnology with support medium using on the basis of phosphogypsum was developed. This technological solution which allows providing the high quality of gas stream purification with a high content of sulfur compounds, particularly hydrogen sulfide (more than 10% of the gas total volume).
