# '''Sediment removal performance''': Mass balance testing at a minimum of seven surface loading rates to determine the capacity of MTDs to retain suspended solids
# '''Sediment removal performance''': Mass balance testing at a minimum of seven surface loading rates to determine the capacity of MTDs to retain suspended solids
# '''Sediment scour and re-suspension test''': Sediment is pre-loaded into the unit and effluent concentrations are measured at a minimum of five surface loading rates to determine how well the units retain captured sediment.

# '''Light liquid capture and retention test''': An optional test in which beads with a density similar to motor oil are pre-loaded into the unit and the number of beads in the effluent during pre-loading and testing are measured to assess the capacity of the unit to trap and retain light liquids.

As of October 2023, there were nine OGS vendors with ISO 14034 verifications (as shown in the [[Oil and Grit Separator#Testing and Verification|table]] above), and 12 different OGS designs that have been verified.

Sediment removal performance results were relatively consistent across different MTD designs, with slightly more variation at higher surface loading rates (see Graph below). <br>
