<p>Oil and grit separators (OGS) are devices which use physical principles to improve water quality. Typically these are underground chambers installed in catchbasins or manholes. Many commercial and custom configurations exist for both new installations and retrofit scenarios.

<p>One method is to incorporate baffles within a tank or chamber:

<li>The first baffle slows the incoming water flow, encouraging any larger, heavier particles to drop out of the water, </li>
<li>A second baffle skims the surface of the water, preventing floating debris, oils and grease from passing. </li>

<p>Another option is a hydrodynamic device, which forces the incoming water flow into a circular vortex:
<ul>
<li>The vortex motion forces the larger, heavier particles are outwards and downwards into a lower chamber, </li>
<li>Floating debris, oils and grease are trapped behind a baffle or in small tank area, towards the top of the main vortex chamber. </li>
</ul>
