The problem of a proper water management is not only the decreasing water resources in the world, the consumption of which exceeds possibilities of their renewal, but also deteriorating water quality to the extent preventing from natural self-cleaning processes. Due tothe above, it is extremely important to protect water resources, that are treated wastewater receivers. Removal of microorganisms found in sewage and sewage sludge is a significant problem of the 21st century.

The paper presents the evaluation of the possibility of the use of a biomass with high moisture content in a cogeneration plant with gas piston engine. The dried sewage sludge-derived syngas is used as a fuel. Sewage sludge are characterized by about 70 wt% of moisture content after the dewatering process. The drying process which is applied as the next step requires great amount of energy. For this reason the thermal integration of the drying process with a piston engine which produce a

The use of low-calorific value gases is a way to gaseous fuels supply diversification. LCV gases present an application potential in various technologies e.g. reburning process. The experimental investigation of the reburning process in small scale coal-fired boiler using sewage sludge-derived syngas was carried out. The influence of the LCV gas stream on the nitrogen oxides emission reduction was analyzed. The emission reduction reached almost 30% with 11% gas share in thermal input.

Basing on the data provided by the Central Statistical Office, in 2016 the length of the sewerage network in Poland exceeded 154 thousand kilometers, with the number of connections to buildings being approx. 3.2 million. The volume of sewage discharged from households in 2016 amounted to 938.1 hm3. The generated municipal sewage is subjected to treatment processes in over three thousand treatment plants, of which 106 produce biogas from the fermentation of sewage sludge [1

strategy of dealing with municipal sewage sludge for several years. Both concepts combine common objectives such as sustainability, prevention of climate change and progressive water eutrophication. The basic principle behind both concepts is the resource saving, recovery and use of renewable energy .

Wastewater and sewage sludge is a place of occurrence of the many microorganisms, including pathogenic and relatively pathogenic bacteria. Their number is subject to significant changes over time, and depends on many factors such as: type of wastewater flowing into the treatment plant, or the presence of substances that are a source of food for microorganisms. Wastewater allows microorganisms to enter other environments, such as receiver waters or soil. The type of pathogens
