AMI Direct SDI Portable Silt Density Index Test Kit

AMI Direct SDI Portable Silt Density Index Test Kit

Suspended solids and colloidal materials in feed water are one of the biggest problems in reverse osmosis systems. Silt Density Index (SDI) is the established measurement of this fouling problem, in which a 0.45 micron filter is exposed to the feed water under pressure and filtration rates are calculated. In most cases, an SDI of less than 5 is considered acceptable for the reverse osmosis systems.

AMI’s direct SDI test kit is 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 is offered for pressures below 30 PSI.

  • Ensure optimum performance of reverse osmosis systems by verifying the feed water SDI is within acceptable limits.
  • SDI Testing before a system installation can determine any pretreatment required during system design.
  • Test manifold is built into a portable travel case with easy connection/disconnection for on-site testing.
  • Optional booster pump assembly (sold separately) is available for testing feed sources with pressures below 30 psi.
  • Manufactured in our ISO 9001:2015 Certified Facilities
