# '''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 are measured to assess the capacity of the unit to trap and retain light liquids.

There are currently eight OGS vendors with ISO 14034 verifications (as shown in the [[Oil and Grit Separator#Testing and Verification|table]] above). The list of manufacturers and test results of all OGS products and other verified technologies can be found [https://etvcanada.ca/home/verify-your-technology/current-verified-technologies/ here]. Sediment removal performance results were relatively consistent across different MTD designs, with slightly more variation at higher surface loading rates (see Graph below). <br>
