GREASE INTERCEPTOR HAVING A BAFFLE

Disclosed embodiments relate to a grease interceptor for treating wastewater by separating and retaining contaminants. In some embodiments, the grease interceptor may comprise a tank having a top wall, a bottom wall, opposing side walls, an upstream end wall, and a downstream end wall, a baffle extending transversely between the opposing side walls and dividing the tank lengthwise into a first chamber and a second chamber, wherein the baffle comprises, a hollow center compartment having an inflow opening for receiving a flow of wastewater and a slot opening for discharging the flow of wastewater into the first chamber, a first outer compartment and a second outer compartment located on opposing sides of the center compartment, wherein the first outer compartment and the second outer compartment each comprises an inlet opening for receiving the flow of wastewater from the first chamber and an outlet opening for discharging the flow of wastewater into the second chamber. The grease interceptor may further comprise an inflow pipe configured to direct the flow of wastewater from a source to the inflow opening and an outflow pipe configured to direct the flow of wastewater from the second chamber through an outlet standpipe to an outlet.
