| Abstract | Introduction Along with expanding urban population and development of cities, and resulting increase in demand for water, in recent years production of municipal wastewater has grown drastically. On the other hand, enhanced public awareness about the water pollution problems has mandated stricter environmental rules and penalties concerning wastewater discharge. These have led to rapid the construction and installation of urban Waste water treatment plants. Now production of significant volumes of domestic wastewater and uncontrolled discharge into receptive and underground water resources, faced the planners of the national projects with serious problems. Such that predictions indicate until the year 1400 about 800 urban wastewater treatment plants are obligatory in the country that necessitate enormous financial and human resources investment. Such an investment entails conscious selection of treating process according to the economical and engineering criteria. In recent years, many studies and optimization models are considered to choose the best wastewater treatment process. Although, most of them have only regarded the financial costs of the investment and operation, while the best option is not always the cheapest one. Selection of the optimized process of municipal wastewater treatment is an important and multi-dimensional issue. If we regard outcomes of a failed plan and wasted investment, the essence of satisfaction of environmental standards based on a systematic and scientific procedure to select the treatment process will be multifold. Such a process should maintain minimal environmental effects and economic feasibility together. In selecting the appropriate option for wastewater treatment, adoption of primary factors and decision criteria require close attention as well. Since most of these factors are complexly interrelated, i.e. change in one parameter nonlinearly affect rest of the parameters, setting up a decision-making model and interpolating it with a set of effective and independent parameters is challenging. Hence, the use of Multi-Criteria Decision-Making (MCDM) techniques would be helpful. Several MCDM methods are presented up to now, such as weighted sum model, the TOPSIS method and Analytic Hierarchy Process (AHP). AHP is a useful method while working with multiple and probably opposing criteria and objectives. Adoption of AHP enables us to evaluate the different objectives and to determine differences between two options by “priority vectors”. The ultimate goal of this approach is to identify the best option and also sort all possible options according to compatibility with all decision criteria simultaneously. |
