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 website provides an introduction of membrane processes including microfiltration nanofiltration, and ultrafiltration.
This document gives an overview on the role of chlorination in disinfecting drinking water. It includes information on chlorine and waterborne disease, disinfection by-products, and compares chlorine to alternative disinfection methods such as ozone and ultraviolet radiation.
