An Integrated Approach to Understanding and Reducing Fat, Oil, and Grease (Fog) Deposit Formation for Sustainable Sewer Collection Systems

The proposed project seeks to understand and reduce the formation of FOG deposits that lead to environmentally detrimental SSOs in sewer collection systems by achieving the following objectives: a) perform detailed bench scale tests that attempt to recreate FOG deposits and determine parameters that significantly influence their formation rate, b) perform bench scale tests to explore treatment options that improve FOG deposit chemical precursor removal with grease interceptors, c) perform pilot scale experiments on a continuous flow sewer collection system that characterizes spatial variations in FOG deposit formation, and d) develop a model to predict FOG deposit formation in sewer collection systems.
