Hydrodynamic Separators

Hydrodynamic separators (HDS), also known as oil/grit separators (OGS), are widely deployed as stormwater treatment BMPs, both in stand-alone applications and as pretreatment devices in a treatment train. HDS target the removal of high specific gravity suspended solids (such as sand, grit, and degraded asphalt), as well as free-floating oil …

SAVI Vortex Grit Removal System

The rotating blades maintain a constant vortex circular flow against the tank sides that allows the grit to slide down the sides of the tank and settle to the bottom. The degritted flow exits the top of the tank and proceeds downstream. The highest grit capture occurs when the grit removal system is preceded by a high capture fine screen.
