Portable Silt Density Index Test Kit

Product Description

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

AMI’s direct SDI test kit is completely assembled
in a portable, compact case, ready for on-site

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.
