- چکیده:
- چکیده انگلیسی: One of the main problems in the quality control of rivers is the high control cost imposed upon pollutant units. The cooperative policy approach in the treatment process between two or more pollutant units is a new and economic perspective in the environmental management of catchment basins. Origins of large amounts pollutants which require a high cost to control pollution are trying to start partnerships with smaller units in establishing joint refineries in order to reduce their own and the whole system's costs. In this study, considering the one way direction of the river's water, the Streeter – Phelps equations were used to simulate the river. The Ant Colony Optimization was used as an efficiency model in order to acquire the best scenario of cooperation based on the maximum elimination of pollution and reduction of treatment costs without straying from the river's quality standards. Also the ratio – trade system was used for commercial purposes. After this the cost of the depleting units was split evenly between them using the cooperative game theory. The efficiency of the model was evaluated by qualitative and quantitative analysis of the Zarjub River in Gilan province of Iran. Three main scenarios were taken to mind for cooperative trading to take place. Carrying out the trade – partnership model could play positively large role in sufficing the quality the control of river water.

- چکیده:
- چکیده انگلیسی: The primary objective of desalination research is the development of a way to produce fresh water at lower cost. The present study investigated two freshwater production methods of Reverse Osmosis (RO) and Multi-Effect Humidification (MEH) (artificial distillation), and analyzed them from an economic standpoint, and subsequently pointed out the important and effective factors in decreasing saltwater desalination expenditure for each one of the mentioned units. Different aspects of these units were investigated as well. However, all the prices are assumed with the current condition and expenses in Sistan Baluchestan province, Iran. The results from economic analyses, obtained employing COMFAR III, showed that, in regions where locals have access to local grid, application of RO unit has no economic justification, while MEH units, powered by solar energy, are more economic in remote regions receiving adequate solar irradiation. However, the water produced by RO can be purchased at 0.02 $/lit, and by solar MEH unit (Respect to introduced characterization), at 0.032 $/lit. Although, the sensitive analysis of IRRs’ variation in proportion to three factors namely sales income, fixed capital expenditure and operational expenditure were conducted.
