Diffuser baffle for grease interceptor

A grease interceptor and diffuser assembly comprising:

• a grease interceptor including:
• a wastewater fluid inflow opening;
• a wastewater fluid outflow opening in fluid communication with the inflow opening;
• a grease collecting chamber hydraulically located between the inflow opening and the outflow opening;
• a floor disposed at a lowermost extent of the grease interceptor;
• an inlet baffle in fluid communication with the inflow opening and the grease collecting chamber, and adapted to direct the fluid downward toward the floor;
• an outlet baffle in fluid communication with the outflow opening and the grease collecting chamber, and adapted to direct the fluid upward from the floor to the outflow opening;
• a ramp disposed on the floor between the inlet baffle and the outlet baffle, the ramp being adapted to direct the fluid flow upward away from the floor;
• a diffuser disposed in the grease collecting chamber, the diffuser including:
• a first panel extending between a first panel lower edge and a first panel opposite upper edge, the first panel being disposed upright adjacent the inlet baffle, the first panel lower edge being elevated above the floor so as to allow the fluid to flow beneath the first panel lower edge;
• a second panel extending between a second panel lower edge and a second panel opposite upper edge, the second panel being disposed upright adjacent the outlet baffle, the second panel lower edge being in contact with the floor so as to prevent fluid flow beneath the second panel lower edge, the second panel having a solid deflector portion adapted to engage the fluid flow from the ramp, deflect the fluid flow away from the second panel, and direct the fluid flow toward the first panel, the second panel and the ramp forming a solids retention area therebetween so as to collect heavy entrained solids;
• a top portion extending transversely between the first panel upper edge and the second panel upper edge;
• an interior space enclosed by the first panel, the second panel, and the top portion, the interior space being in fluid communication with the grease collecting chamber;
• and
• apertures through the first panel and the top portion, and openings through the second panel, so as to allow the fluid to flow from the interior space through the first panel, the second panel, and the top portion, into the grease collecting chamber;
• wherein
• the diffuser is adapted to cause the fluid to flow from the inlet baffle beneath the first panel lower edge into the interior space, upward through the apertures and openings into the grease collecting chamber, and downward into the outlet baffle;
• and
• fats, oils and grease (FOG) will separate from the fluid in the grease collecting chamber.
