Technologies for wastewater treatment appropriate for reuse: potential for applications in Greece

Abstract

During the past 15 years, a wide variety of technologies have been developed that can be used for the treatment of wastewater for reuse applications. To assess the need for alternative technologies, potential reuse applications are reviewed. Changes in wastewater management, including the growing importance of decentralized wastewater management, is examined. The role of decentralized wastewater management is considered with respect to wastewater treatment, reclamation, and reuse. Technologies are presented and discussed for a wide range of reuse applications, ranging from individual homes to large centralized systems. The performance of representative technologies is assessed. A brief review of the water resources of Greece is presented to provide some perspective on the potential for wastewater reclamation and reuse in Greece.
