Selection of An Efficient Desalination Technology to Treat Brackish Water for Domestic Application in Metropolitan Cities In India Using Multicriteria Analysis
Journal Title: International Journal of Industrial Engineering & Technology (IJIET) - Year 2019, Vol 9, Issue 1
Abstract
This paper emphasizes the requisites of desalination plants in India. Effectual desalination technology is selected to treat brackish groundwater in metropolitan cities utilizing a case-study centered on Hyderabad. It presumes tremendous significance as it supplies drinkable water in metropolitan cities, all through the year. It is emerging as the chief challenges to the government on account of escalating population and frequent drought-like conditions. In the wake of this, unfiltered groundwater is utilized for direct consumption owing to the high costs of purification. Establishing desalination units to treat brackish water would augment conventional sources to supply drinking water at a low cost. This paper proffers a model to select an effectual desalination technology by evaluating the numerous prevailing techniques utilizing MCE (multi-criteria evaluation). After consulting decision-makers, the experts in the desalination industry identify 9 criteria and 5 alternatives. Analytic Hierarchy course is ascertained as the suitable MCE technique where 5 alternatives are assessed by considering each criterion on expert’s opinions. The results exposed that RO (reverse osmosis) is the most pertinent technology for the selected city followed by electrodialysis, vapor compression, multi-effect distillation and multi-stage flash in the decreasing sequence of priority.
