This paper presents a continuous-time mathematical formulation for freshwater and wastewater minimisation in multipurpose batch plants with and without a central reusable water storage facility. The minimisation of wastewater is achieved through the exploitation of recycle and reuse opportunities. A superstructure that entails all the possible recycle and reuse possibilities is used as the basi...

When addressing urban water problems, it is no longer adequate to consider issues of water supply, demand, disposal, and reuse independently. Innovative water management strategies and opportunities for water reuse can only be properly evaluated in the context of their interactions with the broader water system. An integrated linear deterministic optimization model is applied to Beirut, Lebanon...

Public support is crucial for successful implementation of wastewater reuse projects. This paper analyses the findings of a questionnaire-type survey (256 participants) conducted to determine the attitude of Israeli urban public towards possible urban reuse options. The paper summarises the support/objection to 13 reuse options and the correlation between support and environmental awareness and...

Wastewater reuse is being widely promulgated to help address the global freshwater resource crisis. It can assist in reducing extraction of freshwater from the environment, and reuse of wastewater lessens the need for environmental discharge, which is clearly beneficial to receiving waters. But the practice itself also has the potential to be detrimental to natural and human environments: soil ...

The current paper assesses the reliability coefficients of fifty six low-cost, full-scale wastewater treatment plants, including nine different treatment technologies for wastewater reuse in aquaculture and agriculture in northeast Brazil. This was carried out with the aim to evaluate alternatives for sustainable wastewater reuse in communities experiencing water scarcity. The technologies eval...

Majority of the industrial activities in Thailand are concentrated around Bangkok Metropolitan Area. The ever increasing industrial activities have led to over exploitation of water resources and discharge of significant pollution load. Therefore, it is important to identify the wastewater reuse potentials and develop strategies for its promotion within the industrial sector. Although technolog...

this study aimed to identify problems arising from lack of knowledge in interest groups about wastewater reuse and delphi survey was conducted. according to experts, the most important factor that may cause the public resistance against the use of treated wastewaters is “health concerns”. this factor may be resulted from “lack of trust on the responsible organizations” and “ignorance about trea...
