pipelines . In addition, it contributes to the phenomenon of condensation, which leads to the formation of so-called corks and erosion, increasing the volume and decreasing the calorific value of gas. In addition, liquid water accelerates the corrosion process and makes it difficult to measure the flow rate, especially when the gas contains carbon dioxide and/or hydrogen sulphide. For the above reasons, it is necessary to dehumidify the gas before transportation or processing [8, 9].

interaction of hydrogen sulphide, which average concentration in the sewage air, during an exemplary 84 hours was 29 ppm. Concrete was gelatinous fine with noticeable outer pellicular layer of 1 mm thick and the inner layer containing aggregates (grain < 1 cm). Sulfur oxidizing, sulfates reducing, Fe2+ oxidizing bacteria, aerobic heterotrophs, anaerobic heterotrophs, nitrifiers and denitrifiers were determined. In the concrete sample, no sulfate-reducing bacteria were detected under the film-like layer
