Use of Enzymes within Grease Interceptors: There are many factors to consider in your assumption that enzymes are the fix for Food Service Establishment, (FSE) grease interceptor preventative maintenance. I would like to address biological approaches to control Fats Oil and Grease, (FOG) compared to standard waste removal process being applied to a FSE greases interceptors. Conventionally speaking the term biological remediation means the use of specific enzymes and/or the use of bacteria themselves that secrete FOG-cleaving enzymes. Through Biological Remediation the secretion of FOG cleaving enzymes causes cleaving to the glycerol backbone leaving free glycerol and triglycerides within interceptor body. Beta Oxidation is then caused, enabling the reduction in fatty acid carbon count. Depending on your species of bacteria, and the constituents of your waste-stream the bacteria may not secret the necessary enzyme to break down the oil and grease molecules, thus will not be capable to utilize the FOG as a food source. If this occurs the eventual accumulation of fatty acid, volatile organic acid and others, may accumulate and thus lower the pH within the interceptor body to a point where the pH is at or below 4.0. Additionally, the importance of retention time within the interceptor cells can not be overstated. At a minimum and depending on site specific bacteria application rate, gallons per day (GPD), and flow to interceptor, the retention time should be 24 hours to a maximum of 48 hours. As you can see the maintaining of such a process requires much more than simply dumping enzymes down the drain from time to time. The FSE owner/manager is required to inform the Cedar City Pretreatment Coordinator prior to introduction of any enzyme causing bacteria into the waste stream.
