Grease Trap Odor
Grease Trap Odor
(OP)
Does anyone have any referenaces or informaiton about odor problems in terms of grease traps?
Here's the problem:
We have a client, a retirement home that installed a grease trap from Monarch Products Company Inc., which we specified. Conventionally, only kitchen waste enters the grease trap. The effluent from the grease trap then enters a standard grinder pump along with the waste from one (1) bathroom. Both are then pumped up to a gravity sewer elevation and drain to the plant.
The problem occurring is smell from the grease trap travels through grinder pump back the line to the bathroom and vents to the top of the building.
The trap smells is so bad that the building ventilation on the roof picks up the odor and spreads it through the entire building. We have tried extending the vent approximately 10’ but that didn’t work.
I believe just placing a standard lateral trap between the bathroom and the grinder pump will solve the problem but I want documentation that I can reference.

We use a biocatalyst to treat a restaurant grease trap in the Sacramento area. They to had been experiencing odor from the grease trap prior to treatment. The hydrosulfate off gassing even discolored the copper vent pipe. Since use of the biocatalyst, the odor problem has been eliminated.

I used to empty fast food restaurants in about 30 seconds when the lid came off the fat trap!
Biocatalysts/enzymes can actually make this problem worse if not used properly. We recommended continous dosing, and a trap designed not to retain the grease, but to allow reaction with the enzyme.
