Development and validation of system design principles for water reuse systems

摘要

Decision support software (DSS) for Water Treatment for Reuse with Network Distribution (WTRNet) has been developed within the AQUAREC project on "Integrated Concepts for Reuse of Upgraded Wastewater",under the Fifth European Community Framework Programme.The overall objective of work conducted as part of the AQUAREC project has been the development and validation of system design principles for water reuse systems.The DSS provides an integrated framework for optimisation of treatment and distribution aspects of water reuse and the selection of end-users,and has been used in the development of the design principles.The principle components of the software (simulation and optimisation models) are presented,followed by the discussion on the software validation.A case study is then illustrated,on which WTRNet has been applied to develop least-cost design alternatives.Design principles for water reuse systems that were achieved by applying the WTRNet tool are presented,in which the importance of utilising formal optimisation in determining the most promising design alternatives is demonstrated.
