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 form...

| 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. 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
utilized for developing the CFD model. The kinetic parameters and physical values are
based on previous experimental work and literature. The CFD Eularian-DEM
multiphase model has shown a good potential for simulating the wastewater flow
and demonstrated the applicability of CFD to simulate and track the transport and
deposition of FOG particles into the sewer pipe walls. |
