RASAYAN Silt Density Index (SDI) kit is used to determine the fouling potential of water feeding a membrane filtration process such as a reverse osmosis (RO) system.This test is defined by its specific procedure (ASTM D-4189). The ASTM procedure should be referenced for a more detailed description of the procedure.
The nature of this test is such that it cannot be run in the laboratory. The SDI test should be run daily on the water entering the RO membranes after the cartridge filters. This frequency can be reduced to weekly once background data proves that less frequent sampling is sufficient. As such, a sample tap should be installed on the RO machine after the cartridge filters.
This test can also be run across vessels such as filters or clarifiers to see if they are doing the job expected of them. SDI tests on the raw supply water should be part of every feasibility study for an RO system and it is good to run one periodically during operation of the system to make sure changes haven't occurred.
It is recommended practice to keep a record of SDI values and filters to observe changes over time.
