Abstract Hydrogen sulfide (H2S) is one of the main contaminants found in biogas which is one of the end products of the anaerobic biodegradation of proteins and other sulfur-containing compounds in solid waste. The presence of H2S is one of the factors limiting the valorization of biogas. To valorize biogas, H2S and other contaminants must be removed. This study evaluated the performance of a pilot-scale biotrickling filter system on H2S removal from landfill biogas. The biotrickling filter system, which was packed with stainless-steel pall rings and inoculated with an H2S-oxidizing consortium, was designed to process 1 to 10 SCFM of biogas and used to determine the removal efficiency of a high concentration of hydrogen sulfide from landfill biogas. The biofiltration system consisted of two biotrickling filters connected in series. Results indicate that the biofiltration system reduced H2S concentration by 94–97% without reduction of the methane concentration in the outlet biogas. The inlet concentration of hydrogen sulfide, supplied to the two-phase bioreactor, was in the range of 900 to 1500 ppmv. The hydraulic retention times (HRT) of the two biotrickling filters were 3.9 and 0.9 min, respectively. Approximately 50 ppmv of H2S gas was detected in the outlet gas. The maximum elimination capacity of the biotrickling filter system was found to be 272 g H2S.m− 3.h− 1. During the biological process, the performance of biotrickling filter was not affected when the pH of the recirculated liquid decreased to 2–3. The overall performance of the biotrickling filter system was described using a modified Michaelis–Menten equation, and the Ks and Vm values for the biosystem were 34.7 ppmv and 200 mg H2S/L.h− 1, respectively.

The use of Nutriox® and ferric chloride to suppress hydrogen sulphide and odour generation in rising mains is evaluatd in a pilot scale study. Without chemical dosing the hydrogen sulphide built up to the commonly predicted levels after six months. Thereafter, addition of both Nutriox® and ferric chloride to sewage entering the rising main totally suppressed the formation of H2S. Nutriox also nearly totally suppressed the odour measured olfactometrically. The use of ferric salt at near stoichiometric levels effectively removed dissolved sulphide. Odour removal was generally good though on occasions reduction of dissolved sulphide levels to below 0.1 mg/l was not guaranteed to be accompanied by near total suppression of odour generation. The use of ferric ions at stoichiometric levels, after H2S and odours have formed in the rising main, also eliminated the dissolved sulphide. When used in this way, a significant residual odour potential, 110,000 ou/m3 remained in the sewage. The simultaneous reductions of odour and hydrogen sulphide observed in this study implied an apparent threshold odour concentration of 0.1 ppb for H2S, significantly lowr than most values quoted in the literature.

Sulphate-rich industrial effluents present a serious environmental pollution problem. A biological sulphate removal process has been developed for the treatment of such effluents. In this process, sulphate is converted to hydrogen sulphide in the anaerobic stage when an energy source, such as molasses, sugar or producer gas is added. The hydrogen sulphide is stripped off in a stripping stage, with a carrier gas such as nitrogen. The gas is recycled through a ferric solution where it is oxidized to elemental sulphur. In a subsequent aerobic stage, degradation of organic carbon residuals and calcium carbonate crystallization are achieved simultaneously. In this study the anaerobic stage of the process was evaluated on pilot scale. After the inoculation period, sulphate was removed continuously for a period of 100 days from 2200 mg/l to below 200 mg/l. For the first part of the study acetic acid served as energy source as the sugar content of molasses was allowed to ferment. Thereafter fresh molasses was supplied as energy source and the bacterial culture had to adapt to utilize sugar in molasses as energy source. A volatile suspended solids (VSS) concentration of 27 g/l was present in the packing material of the anaerobic reactor. With this VSS-value, a hydraulic retention time of 12 hours was needed for sulphate removal.
