Abstract
A grease interceptor for use with a wastewater treatment system comprises a tank which is divided by a baffle into a first chamber and a second chamber. Wastewater flows from an inflow pipe into a first chamber of the tank. The wastewater may then flow through openings in the baffle to a second chamber of the tank. The wastewater may then flow through an outlet pipe in the second chamber to exit the system. The inflow pipe may comprise a flow restrictor which may restrict the flow of wastewater within the inflow pipe.
Claims20
An adjustable flow restrictor configured to regulate a flow of wastewater through an inflow standpipe of a grease interceptor, wherein the adjustable flow restrictor comprises:
- a rotatable cap, wherein the rotatable cap comprises at least one handle configured to adjust the rotatable cap within the inflow standpipe;
- and
- a flow restrictor projection extending from the rotatable cap into the inflow standpipe, wherein the flow restrictor projection comprises a curved projection configured to restrict the flow of wastewater within the inflow standpipe.
A grease interceptor for treating wastewater by separating and retaining contaminants, wherein the grease interceptor comprises:
- 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, dividing the tank lengthwise into a first chamber and a second chamber, wherein the baffle comprises at least one exit opening for discharge of wastewater from the first chamber into the second chamber;
- an inflow pipe configured to direct wastewater from a source through an inflow standpipe to the first chamber;
- an adjustable flow restrictor comprising a rotatable cap and a flow restrictor projection configured to regulate a flow of wastewater into the inflow standpipe;
- and
- an outlet pipe configured to direct wastewater from the second chamber through an outlet standpipe to an outlet.
