Strategies to Reduce the Impact of Fats, Oils and Grease on Publicly Owned Treatment Works
Presenter / Wastewater Training & Compliance
Approved by the TCEQ for two hours of Wastewater Operator CEU Credit.
Fats, oils, and grease (FOG) has historically been one of the biggest challenges that wastewater collection system and treatment plant operators face. Excessive FOG discharges from commercial and residential sources can result in unauthorized discharges (sanitary sewer overflows). Excessive FOG can also clog wastewater collection system piping, affect operation of lift stations, reduce life expectancy of concrete manholes and wet wells, and require costly maintenance. Wastewater treatment plants and equipment can also be adversely impacted by FOG and affect the ability to maintain compliance with TPDES discharge permits. This presentation will discuss sources of FOG and impacts on POTWs, how to prevent and control FOG, unauthorized discharge reporting requirements in Texas, what to consider when cleaning sewer lines in order to reduce slug discharges and maintain compliance with TPDES discharge permits.
