Preliminary study on the application of multiphase DEM for the prediction of fat,oil and grease (FOG) deposition in sewer pipe lines
Fat oil and grease (FOG) deposition into sewer pipes can block the pipes and restrict the wastewater flow causing backflows and sanitary sewer overflows (SSOs). Understanding the wastewater flow and transport of FOG particles is a key step for predicting the particles deposition and blockage forma...

| Summary: | Fat oil and grease (FOG) deposition into sewer pipes can block the pipes and restrict the wastewater flow
causing backflows and sanitary sewer overflows (SSOs). Understanding the wastewater flow and transport of
FOG particles is a key step for predicting the particles deposition and blockage formation. In this research,
ANSYS FLUENT was used for simulating the flow of FOG particles and its deposition onto the sewer pipe.
The multiphase Eularian-Lagrangian model with discrete Phase method (DPM) was used for developing the
CFD model. The kinetic parameters and physical values are based on previous experimental work and
literature. The model will assist in predicting blockages by acting as an early warning system for the
wastewater municipalities.
