Using Analytical Hierarchy Process (AHP) for Selecting the BestWastewater Treatment Process (Case Study in Amol City)

In current work, Analytical Hierarchy Process (AHP) method is applied to select the ideal anaerobicwastewater treatment process. This strategy can be used for complex multi-criteria choice making toget perceptible outcomes. Thedistinctive anaerobic procedures utilized in Iranian industrial domainsincluded Up-flow Anaerobic Baffled Reactor (ABR), Up-flow Anaerobic Sludge Blanket (UASB),Up-flow Anaerobic Fixed Bed Reactor (UAFB), Anaerobic Lagoons (AL) and Contact process (CP).The procedures are measured based on overall circumstances in wastewater treatment plants (WWTP)in industrial domains and on expert decisions applying financial, technical, ecological, andorganisational principles. The outcomes are evaluated by means of the Expert Choice Software.Eventually, the presented procedures are positioned as 1 to 5 in a gradually decreasing order of UAFB,ABR, UASB, AL and CP. Theanalysis presents the impacts of the parameters on variations in theoutcomes which are connected for the aforementioned principles
