Kurzfassung englisch:
Different methods to combat H2S formation in pressure sewers were investigated in some existing sewer systems. Experimental results of H2S generation were compared with theoretical production rates according to calculation from literature. In most cases the calculated H2S formation overestimated the measured results. The removal of biofilms from the pressure pipes with different pigging technologies and chemical treatment was only effective for few days. Very successful was the application of different iron salts and nitrate solutions to either precipitate sulfide or to avoid anaerobic condition in the pipe. Equally successful was the application of compressed air for transport or aeration in pressure pipes. The different methods were evaluated for their applicability and economy depending on specific conditions prevailing.
