Performance of Grease Abatement Devices for Removal of Fat, Oil, and Grease

Diesel-like hydrocarbon fuels by catalytic cracking of fat, oils, and grease (FOG) from grease traps

“…Despite the proposal of processes and devices for removal of fats, oils, and grease (FOG) from grease-containing wastewater, reported in the literature [1,5,7e10], such as grease trap filters [1,5], ultrafiltration [9], and the use of microorganism [10], the most common pretreatment for fats, oils, and grease (FOG) removal from grease-containing wastewater is a grease trap [5,7]. In this context, based on the lipid nature of fats, oils, and greases (FOG), processes have been proposed for converting this residual fat material into biofuels [4,6,11e14], as well as to improve biogas production from anaerobic digesters at wastewater treatment units [7,15,16].…”

Problems, Control, and Treatment of Fat, Oil, and Grease (FOG): A Review

“…This method involves installing a grease interceptor GI that separates the FOG from the restaurants sullage reducing, its concentration in the effluent 21 . Recent efforts have been made to enforce good management practices at restaurants and food service establishments to ensure the right disposal of residual FOG 26 .…”

“…FOG components are introduced into the sewer system either by direct dumping into the sewer or by escape from grease traps GTs that are usually installed in restaurants. The GTs interceptors are designed to trap most of the FOG in the restaurant effluent and separate it from the sewage before reaching the sewer pipe 21 . However, the efficiency of the GT depends strongly on the frequency of its maintenance 22 .…”

Experimental and Computational Investigations of Baffle Location Effect on the Performance of Oil and Water Separator Tanks

“…The oil phase is in the form of drops with an average diameter of 150 μm and a density of 910 kg/m 3 . Water is discharged through the inlet slot at a flow rate of 2 L/s, whereas the inlet slot of 5% by volume oil [9] in water mixture has a constant discharge rate equal to 30 mg/L. 300×122 grids were chosen for the computation.…”
