2、ment in small and medium-sized municipal wastewater treatment plant-new technical solution Anna Grobelak, Anna Grosser, Magorzata Kacprzak, Tomasz Kamizela Abstract Although sewage sludge generated by most large wastewater treatment plants is treated as waste, this waste is both a source of energy a
3、nd nutrients. Moreover, mainly in the small and medium-sized installations of municipal wastewater treatment plants is produced sewage sludge that meets the standards for soil application. Unfortunately, the overly simplied operating systems of small wastewater treatments plants cannot provide the s
4、atisfactory content of water in sewage sludge for energy recovery purposes. Therefore, new solutions for sewage sludge treatment are required. The study presents an innovative, energy effective, wastewater treatment and sewage sludge processing in one operational sequence, with signicant energy cons
5、umption decrease and autothermal biomass production. Current research contains detailed technical information about the novel integrated waste water treatment plant and sewage sludge treatment installation as well as cost analysis in comparison to conventional treatments. The aim of this study was t
6、o evaluate the operation of the one prototype line for wastewater and sewage sludge treatment and the assessment of the obtained biomass and fertilizer. This new technology is a solution for small and medium-sized municipal wastewater treatment plants and is leading to change the conception of wastewater treatment process as a whole and is resolving the management of sewage sludge at the place where it is generated. In described process the sewage sludge is adequately treated by the inst
