Lovibond Manual SDI kit for determination of silt density index in pure water systems.
Kit includes the following:
Manual SDI kit- silt density index kit
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.
Silt Density Index (SDI) is a test used to determine the levels of colloidal and particulate suspended solids in the feedwater to reverse osmosis (RO) systems. This in turn will enable you to estimate the fouling potential. This measurement is of importance as it can be used to predict the lifetime of the RO membrane. This can help save time and money. It is measured following the test...
