RASAYAN make sdi kit is useful for determination of silt density index of water. we are the leading manufacturer of sdi kit in ahmedabad, gujarat, india.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.Completely assembled in a portable, compact case, ready for on-site testing. Includes ASTM instructions for measuring silt density index. Minimum of 30 PSI water pressure required. Optional Pump Assembly Kit available for pressures below 30 PSI.

Suspended solids and colloidal materials in feed water are one of the biggest problems in reverse osmosis systems. Even though most systems have some pre-treatment including 5 microns pre filters, these fine particles are responsible for fouling of reverse osmosis membranes. In order to have some measure of the degree of this fouling problem, a concept called silt density index is used. Here a 0.45 microns filter is exposed to the feed water under pressure and filtration rates are calculated.

SDI test kit is to assess the extent of suspended particulate (solids and colloidal) contamination in water & can be applied in process solutions also. A SLIT DENSITY INDEX (SDI), also referred to as Fouling Index. Although most systems have some pre-treatment these fine particles are responsible for the fouling of reverse osmosis membranes.
