Comparative analysis of wastewater treatment technologies

摘要: The aim of this study is to apply the principle multi-criteria decision-making (MCDM) theories on different types wastewater treatment technologies. An increase in production and discharge increasing; therefore alternatives are needed. With population growth, urbanization industrialization increasing amount pollutants our environments that leads more from both domestic industries. These wastewaters produced large volumes must be absolutely treated before discharge. Therefore, there need for technologies cost effective, easy maintain, low energy use etc. This will some criteria Fuzzy PROMETHEE analyze based these criteria. outcome help concern parties chosen best among give an insight concerned such as engineers, town planners other government personnel’s making decisions. common most commonly used were evaluated compared certain using fuzzy theory Nano-filtration Method recommended followed by Activated Sludge (AS) research.
