Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.
This study evaluates the performance of the filter under various set-ups, to investigate long-term removal efficiencies to improve the filter design and to implement the filter in arsenic affected villages.
