Abstract:

The selection of optimum high strength wastewater treatment process is complicated. Be familiar with wastewater treatment methods is not enough to design a plant. In this research, five alternative wastewater treatment methods (upflow anaerobic sludge blanket (UASB) + membrane bioreactor (MBR), UASB + Extended aeration (EA), Anaerobic baffled reactor (ABR), anaerobic lagoon (ANL) + aerated lagoon (AL), and sequencing batch reactor (SBR) + ABR) for high strength wastewater were investigated and ranked based on the analytic hierarchy process (AHP) fuzzy method. These treatment methods were investigated and ranked based on five criteria (energy consumption, effluent total suspended solid (TSS), effluent chemical oxygen demand (COD), cost, and level of technology). Rating the different options of wastewater treatment plant was done by expert decision makers in this field. The results show that for typical high strength wastewater using an UASB reactor followed by a MBR is the most appropriate alternative to treating the wastewater.

A fuzzy multi-criteria decision method for ecotourism development locating

The County of Khorram-Abad enjoys a high potential for ecotourism because of its mountains, forests, natural mineral springs, natural waterfalls and diversity in folks and cultures. But, un-planned and uncontrolled ecotourism can have negative effects on environment, economy, culture and even the security of eco-tourists. The main purpose of this study is to present a fuzzy multi-criteria decis...

A Hybrid Fuzzy Multi-criteria Decision Making Model Based on Fuzzy DEMATEL with Fuzzy Analytical Network Process and Interpretative Structural Model for Prioritizing LARG Supply Chain Practices

In recent years, taking advantage of LARG supply chain (SC) paradigm, a combination of four paradigms (clean, agile, resilience and green) has been increasingly employed. For capturing the advantages of LARG in SC, companies needed to recognize proper practices and implement them with appropriate planning and infrastructure. However, one of its deficiencies is lack of proper method in the prior...
