Lovibond SDI Silt density index manual test kit

Manual SDI kit- silt density index kit

• SDI calculations in just 15 minutes
• Ideally suited for reverse osmosis plants

Enables calculation of membrane fouling time, backwash frequency and membrane lifespan

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. The SDI of the feedwater is required to calculate membrane fouling time, backwash frequency and, ultimately, membrane lifespan. The Lovibond® test kit gives the RO engineer instant SDI values, increasing the speed and effectiveness of the installation.

Suspended solids and colloidal materials in feed water are asignificant issue in maintaining membranes in reverse osmosis systems.  Pre-treatment can address some of these isue for example membrane pre-filters, any fine particles in the feed water can be esponsible for the fouling of reverse osmosis membranes.

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