The Silt Density Index (SDI) is a measure of the solids or particulate content of water and is of specific importance when commissioning reverse osmosis plant.

• SDI calculations in just 15 minutes
• Ideally suited for reverse osmosis plants
• Enables calculation of membrane fouling time, backwash frequency and membrane lifespan

The kit utilises a membrane/flow meter system to enable SDI calculations in just 15 minutes. Sufficient membranes included for 100 tests.
