Abstract:
... This paper proposes a framework based on the group analytic hierarchy process for identifying most desirable technologies for constructed wetland segmentation. A method is defined how to select decision makers whose evaluations should be included into the group decision by calculating different consistency and statistical conformity measures, and their aggregation into the new metrics. The consist ...

Abstract:
... The reuse of discharged cooling tower water (CTW) in the cooling tower itself could reduce fresh water intake and help mitigating fresh water scarcity problems. However, this requires desalination prior to its reuse, and hindering fractions, such as conditioning chemicals, should be removed before desalination to obtain a higher desalination efficiency. Constructed wetlands (CWs) can provide such ...
