The conditions have been examined under which selected groups of microorganisms might be applied to prevent or significantly reduce the generation of odour from the processing and storage of the wastewater sludge. A series of experiments were conducted on a semi-industrial scale, using effective microorganisms (EM) activated in molasses solutions. The analysis of the results showed that the biopreparation modified the biochemical processes most effectively when a structural material was added to the sludge. The processing of the sludge with added EM caused a 20–26% reduction in odour emissions, despite an increase in ammonia emissions. It also led to a higher dry matter content, which indicates a better dewatering ability of the sludge treated with EM. It can be concluded that the treatment of wastewater sludge with EM and the structural material when the C/N ratio is low can help achieve the desired goal of reducing the odour emission.
