ABSTRACT:
An improved food, oil and grease accumulating apparatus and method of use is disclosed. The improved apparatus includes a pump station to discharge contaminated effluent at a higher flow rate at periodic intervals into a first food separation station for removing food particles. Effluent leaves the food separation station into a second food separation system and then an oil and grease separation station which uses an oleophillic material to attract and coalesce oil and grease particles and permit their advancement along channels to the top region of the oil and grease separation station. The oil and grease are removed through an evacuation system while the water is permitted to discharge from the oil and grease separation station into the sewer system.
