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.
The ratio within the chemical oxygen demand (COD) and the biological oxygen demand over 5 days (BOD5) indicates the level of biodegradability of a sample. A low ratio COD/BOD5 (less than 2.0 or 2.5) indicates a high biodegradability, what means that it can be treated easily by a biological treatment.
