FOG Control Additive Field Testing Evaluations Orange County Fats, Oils, and Grease (FOG) Control Study Phase II
Based on the results of the Sewer Line-applied evaluations, the Sewer Line-applied additives do not appear to be comparable to effective line cleaning based on the CCTV images of cleaned sewer pipe compared to the CCTV images after 4 to 6 months utilization of the additive. The Study determined that improving line cleaning practices through the use of post-cleaning CCTV monitoring alone will typically reduce line cleaning frequencies. Therefore, improving line cleaning practices through the use of post-cleaning CCTV monitoring appears to be a more logical focus for sewering agencies until Sewer Line-applied additives are shown to be more effective. There were encouraging results in four of the five FSE-applied evaluations which may provide some evidence that FSE-applied additives could be considered as an alternative to the requirement to install a grease interceptor at FSEs that cannot install a grease interceptor. However, kitchen best management practices (BMPs) were also newly implemented at the four evaluations that provided encouraging results; therefore, it is EEC's opinion that further Study of FSE-applied additives should be conducted evaluating the effectiveness of the additive after improved kitchen BMPs have already been implemented.
