Silt Density Index Test Kit

To Measure the Fouling Potential of Water

The Pall Silt Density Index (SDI) test is a method often used to determine the effectiveness of a pre-treatment process to reduce the fouling tendency of feed water. This test, most suited for field application, references two American Society for Testing and Materials (ASTM) Standards, the original D 4189-95 (reapproved in 2002) and the current ASTM standard D 4189-07.

Benefits

Regular SDI measurements allow the ability to:
  • choose the correct and economical water pre-treatment
  • determine the effectiveness of a pre-treatment process
  • monitor periodically operation of the water treatment sequence
  • follow water quality changes over time
  • detect "difficult" contaminants such as colloids in the feed water

General Instructions for Use

See Technical Guidance document FBSDITGENc provided with the kit.
