The contributions of this thesis bridge two disciplines: environmental science (specifically, wastewater management) and computer science (specifically, artificial intelligence). Wastewater management as a discipline operates using a range of different approaches and methods which include: manual control, on-line automatic control, numerical or non-numerical models, statistical models and simul...

Considering the global climate changes that have disrupted availability of fresh water and led to emergence drought, an effective management strategy for quality must be implemented. In this work, we analyzed possibility used treated being reused effect its use on soil development plants. case irrigation with wastewater, following parameters increased: calcium carbonate equivalent, organic matt...

Presented in this paper is a graphical technique for freshwater and wastewater minimisation in completely batch operations. Water minimisation is achieved through the exploitation of inter- and intra-process water reuse and recycle opportunities. In the context of this paper, a completely batch operation is one in which water reuse or recycle can only be effected either at the start or the end ...

Many wastewater managers in developing countries struggle with the daily operation of urban wastewater systems. Technically well-designed wastewater collection and treatments are often degraded and/or not properly functioning. In this paper, a realistic rehabilitation strategy is developed for the urban wastewater system of Coronel Oviedo (Paraguay), in which the actual performance is unsatisfa...

the aim of this study was to investigate the impact of management information system on employees’ performance of tehran province water and wastewater company in district 5. the present study was an applied research in terms of purpose and a descriptive correlational survey in terms of method. cochran's formula was used to determine sample size which was 219 employees. the statistical samp...

background : application of strategic management processes at the local level can lead to modeling and development of efficient systems of energy, wastewater, and environmental protection through air pollution prevention. this process is only possible through attention to the strengths, weaknesses, opportunities, and threats of hospitals. this study was conducted with the aim of the presentatio...

Across the nation, food service establishments using onsite wastewater treatment systems often experience pretreatment system and/or drain field performance problems. This study used statistical analysis of restaurant management practice and primary cuisine type to observe their influence on five-day biochemical oxygen demand (BOD5), total fats, oils, and greases (FOG), total suspended solids (...

In order to achieve ecological wastewater treatment, a “closed-loop treatment system” is recommended. Many present day systems are a “disposal-based linear system”. The traditional linear treatment systems must be transformed into the cyclical treatment to promote the conservation of water and nutrient resources. Using organic waste nutrient cycles, from “point-of-generation” to “point-of-produ...

Prolonged drought which has occurred everywhere around the world has caused water shortages, leading many countries to consider more sustainable practices, which are called source management practices (SMPs) to ensure water availability for the future. SMPs include the practices of water use reduction, potable water substitution and wastewater volume reduction such as water demand management, r...
