The most prevalent environmental problems that are presented by modern Wastewater Treatment Plants (WWTPs) are, on the one hand the pollution of water bodies, on the other hand the excessive amounts of energy that are required for their proper operation. In the wake of these issues, the exploitation of the energy content of wastewater is a promising solution for improving the performance of traditional WWTPs.An innovative treatment system of biosolids has been installed at the existing WWTP in Rethymno. The system has a capacity of 5,000 m3/day (which is approximately a third of the average daily wastewater supply) and consists of the following processes in sequence: microsieving, drying and gasification. As a result of this treatment there is energy production through microsieved biosolids. That leads to reduced total energy requirements of the WWTP, while simultaneously the discharge of pollutants due to the disposal of sewage sludge is minimized.The continuous wastewater discharges are putting constant pressure on the modern ecological situation. As a result, many of the water bodies across Europe are not in line with the European Union’s Water Directives. The scope of this thesis is to map the laws, regulations and directives for the project in order to indicate its contribution to the formation of the legal framework for wastewater management.The proposed method of wastewater treatment and the utilization of the produced biosolids, contributes to the improvement of the environmental problems arising from the traditional WWTPs. The main objective of the project is the optimization of the output performance of the WWTP in Rethymno during the removal process of the solids contained in the wastewater, resulting in significant reduction of the pollution of water bodies. Furthermore, thanks to the energy production through biosolids, the microsieving - gasification system is energy effective, thus remarkably reducing the energy requirements of the existing WWTP.
