A number of low-cost synthetic filtration media have been proposed for the removal of arsenic (As) from drinking water in areas such as Bangladesh, where exposure to environmental arsenic is a major human health issue. This PhD research project examines the application of recycled glass and waste stainless steel fragments as a practical medium for arsenic removal at a household scale. To assess the performance of recycled glass media as a practical filter bed, glass granules were differentiated by colour, size and mode of glass size reduction (imploded and ground). The selected glass granules were used as media for batch adsorption and column filtration experiments using a prepared As (III) test solution and using natural As-contaminated water in Bangladesh, where recycled glass in column filtration mode was used to treat arsenic contaminated natural water in the presence of other metalloids.
