What we have Learned – Death of FOG Urban Myths:
A look at commonly held beliefs and what experience has taught us.
Andria Swann, Clark Regional Wastewater District, Vancouver, WA
FOG 101 and Case Studies:
Introduction to problems caused to collection and treatment systems by fats, oils and greases and best practices for minimizing the impacts. Case studies will be described to illustrate the range of issues and approaches for mitigating problems.
FOG Ordinance Basics:
Different approaches to developing and enforcing municipal FOG ordinances and the advantages and disadvantages of different approaches.
Sizing Grease Removal Devices:
The size of FOG removal devices can have a significant impact on their efficiency and also the trade-off between operating costs and capital costs. This presentation will identify the different approaches to sizing and how to identify the capital and operating costs of different devices.
Plumbing Code and Pretreatment Collaboration:
Many communities have Pretreatment programs with federal Clean Water Act requirements to establish local pollutant limits and prohibit the discharge of materials that cause collection system obstruction. To meet these requirements, Pretreatment programs enact local sewer use ordinances independently of plumbing codes. This presentation will examine how pretreatment program and plumbing code goals conflict and how they can better complement each other.
FOG Energy Recovery:
Discharging FOG to sewer systems causes problems for maintenance and high energy costs for wastewater treatment. Collecting for energy recovery reduces costs and also reduces greenhouse gas emissions. This session will focus on energy recovery and how Energy Trust of OR can help. There ill be detail on the case study of a FOG to energy project.
Challenges Setting up a FOG Program:
Experts who have faced the challenges of setting up FOG programs will discuss the challenges they have experience and share their approaches and the key lessons they have learned.
“FOG Scout” Preview:
Automated data collection and management is an important element in an effective program so that timely data is readily available. This discussion will describe the FOG Scout approach.
Vince Chavez, Clean Water Services, Hillsboro, OR
Sensor Technologies and Their Application:
Effective sensor technology is essential to knowing what is going on in FOG interceptors and optimizing efficiency and pump-out frequency – this session will review the options and their application.
