Role of the Decentralized Wastewater Treatment in Municipal Water Management

Abstract

Wastewater from various sources may cause public health risk and deteriorate the quality of the receiving water body, where the key factor is on the performance of the collection and treatment system. Design of a sewerage system shall support the transportation of sewage without an extensive biological activity and sludge deposition in the system. Due to urbanization the existing network could be overloaded, the residence time of the fluid is increased. The expansion of the collection system supports the spread of alternative decentralized solutions, such as multiple small capacity wastewater treatment plants (WWTPs) as well as package plants or individual systems including extensive systems. Goal of this study is to analyze the possible decentralized wastewater alternatives. This work has been undertaken as a part of a project founded by the EFOP-3.6.1-16-2016-00025 aiming for the development of water management in Higher Education in the frame of intelligent specialization.
