Figures & Tables

Figure 1.

Example of a change in the concentration of hydrogen sulphide and volatile organic compounds (VOC) in an expansion well, average retention time of sewage about 2 hours, pumping station for household sewage, measurements made with a multi-gas meter MX6 iBrid, measurement accuracy ±0.1ppm, enabling data registration [16]

Media used to determine the presence of selected groups of microorganisms in the samples

MediumA group of microorganismsMethod for determining the presence of microorganisms
WaksmanSulfur-oxidizing bacteriaDetermination of changes in SO4 2- ions concentration using reagent tests cat. No. 114791 (Merck, Germany) before and after incubation
9KIron (II) ions oxidizing bacteriaDetermination of changes in Fe2+ and Fe3+ ions concentration using a titration method with a EDTA solution against the sulfosalicylic acid index
WinogradskiNitrifying bacteriaDetermination of changes in NH4 + and NO3- ions using reagent tests cat. No. 100683 and cat. No. 109713 (Merck, Germany) before and after incubation
