Physico‐chemical Characterization of Grease Interceptors with and without Biological Product Addition
Hardened and insoluble fat, oil, and grease (FOG) deposits are the primary cause of sewer line blockages leading to sanitary sewer overflows (SSOs). However, there have been very few long‐term assessments of the physico‐chemical characteristics of full‐scale grease interceptors (GIs), the first “line of defense” against FOG buildup in sewer lines. In this study, we assessed the physico‐chemical characteristics of two full‐scale GIs (at a restaurant and a retirement community kitchen) over a one‐year period. Statistically significant differences between bioaugmented and untreated cycles were detected for several chemical and physical properties. The treated cycles had lower BOD and COD at the grease interceptor outlet. While the combined data for all treated cycles did not show lower FOG concentrations in the GI outlet compared to the combined data for all untreated cycles, comparison of specific individual treated and untreated cycles show a positive effect due to the addition of product.
