Abstract:The process that can compile and categorize different technologies, according to established parameters, and provide a visually clear representation of the best options that a client or a decision-maker can select is known as technology screening. This research proposes a framework, based on different technology screening methods, that can be applied for selecting technologies applied for surface water treatment and alternative water sources. The technology screening concept was applied as a case study at Ceará state, which is a semi-arid state situated in Brazil that often faces prolonged periods of drought, resulting in water scarcity and the depreciation of the available surface water quality used as intake by part of the population. In this location number of rural communities do not have access to water treatment plants, and they are obliged to rely in inefficient systems that often also compromise the quality of the supplied water. This research considers water treatment and air-to-water technologies. Several drinking water technologies were considered in this research, which were ranked based on the results of the technology screening process. The technologies that received the highest scores, in order, were: nanofiltration, reverse osmosis, sand filtration, and an air-to-water technology provided by a company called Watergen.
