Whether you are a seasoned pretreatment professional or brand new to the industry, a good understanding of grease interceptors is essential to your success. It's just that obtaining the knowledge you need isn't easy. Searching online for even rudimentary information can be confusing and frustrating because there is so much misinformation out there. Grease traps, hydromechanical grease interceptors, automatic grease removal devices, and gravity grease interceptors are all industry terms used to define various types of devices, but what differentiates them? How do they work? How should they be approved?

This course provides a comprehensive education on commercial grease interceptors including the various types, what distinguishes them and how they work. You'll learn the history of grease interceptors and how they have evolved over the years. The course also dives into the model plumbing codes and product standards that govern grease interceptors including connected fixtures, flow control, venting, and installation requirements. The course further teaches traditional sizing practices including fixture volume, pipe diameter and drainage fixture unit methods as well as newer grease production calculation and selection strategies.

The course comes with an 85-page downloadable guide titled, IWs Grease Interceptor Training Guide - 2019, that should be a handy resource. Also, the course will never expire, so after completion, students can go back and review any of the modules in any order as many times as desired. Finally, each student that pays for and successfully completes the course will be issued a certificate of completion to keep for their records.

If you want to become more knowledgeable and have confidence in how to manage grease interceptors in your pretreatment or FOG program, then get started on your education right away by enrolling in this course.

Course Curriculum

Module 1: The History and Evolution of Grease Interceptors

Students will learn the history of commercial grease interceptors and how they have evolved over time. They will understand how rationing and salvaging of fats, oils and grease (FOG) during World War 2, exposed the need for grease interceptors. They will see how testing and rating protocols were developed both for the military and later, commercially. They will learn what led to residential septic tanks being adapted for use as gravity grease interceptors (GGI). They will also learn how grease interceptors have changed and improved in recent years and why it's important to incorporate newer technologies in pretreatment programs today.

Module 2: How all Grease Interceptors Work

Students will learn about gravity-differential separation and how all grease interceptors work. They will learn about the factors that affect gravity-differential separation including bubble size, specific gravity, temperature, viscosity, velocity, flow pattern and emulsification. They will also be given a demonstration of mechanical and chemical emulsification's to understand the impact of emulsions and soaps or detergents on grease interceptor performance.

Module 3: The Model Plumbing Codes that Regulate Grease Interceptors

Students will learn how model plumbing codes deal with the sizing, selection, installation and maintenance of grease interceptors. They will understand the basic requirements of the Uniform Plumbing Code (UPC), the International Plumbing Code (IPC), the National Standard Plumbing Code (NSPC), and the National Plumbing Code of Canada (NPCC). They will also be taught what to look for in local plumbing codes that undermine pretreatment outcomes.

Module 4: The Product Standards that Govern Grease Interceptors

Students will learn what each of the nationally recognized product standards are and how they govern the design, construction and testing of grease interceptors, all types. The module reviews ASME A112.14.3, A112.14.4, A112.14.6, CSA B481, PDI G101, PDI G102, and IAPMO/ANSI Z1001.

Module 5: How to Effectively Size and Select Grease Interceptors

Students will learn how to correctly size and select grease interceptors with the ASPE’s nationally recognized and published two-step method and how it can be incorporated into pretreatment policy. The method uses both flow rate and grease production calculations to determine the appropriate grease interceptor.

Module 6: Maintenance and Inspection Considerations

Students will learn about FOG deposit constituents and the causes of FOG deposit formations. The module teaches basic inspection criteria for investigating field installations of grease interceptors, including setting the correct maintenance intervals, identifying corrosion problems, determining the operating condition of grease interceptors including all component parts and the role and impact of additives.

"As a former Environmental Services Manager responsible for FOG abatement within our pretreatment program, I understand how important is to “get it right” when it comes to protecting collection systems, recovering FOG, and not imposing undue burden on small businesses. This course is the go-to resource for anyone who wants a solid foundation in selecting and managing grease interceptors."

- David McNeil, Founder & CEO, Bluebridge Coops, LLC

"I have worked in the FOG inspection field for several years and I have not found anyone more qualified than Ken to train individuals on the history of grease interceptors, why we need them and how they work. I would highly recommend this course for anyone working in the field of FOG inspection and enforcement. I encourage all to utilize this outstanding resource and training opportunity to enhance your career skills and overall knowledge!"

- Angela Walker, Pretreatment Compliance Coordinator, Brunswick-Glynn JWSC, Pretreatment

"As the former Source Control Manager at Clean Water Services, a surface water and sanitary sewer district in Oregon, I was responsible for managing the industrial pretreatment and industrial stormwater programs and developing and implementing a FOG abatement program within the District and its twelve member municipalities. If this training course had been available at that time, it would have saved us a great amount of time and energy. I would have had my entire staff take the course to better understand grease interceptors and how to more effectively manage them within our program."

- Clayton Brown, MBA, Pollution Prevention Resource Center, Western States Alliance program manager

"Having been involved in the industrial pretreatment program for over 25 years, I can honestly say Ken’s presentation skills and style are top notch! Ken presented at the 20th Annual EPA New England Workshop and did not disappoint with his visuals and live demonstration. He is an energetic and enthusiastic speaker who really know his grease. Ken gives a great talk along with a well-organized presentation."

- Jay Pimpare, Regional Pretreatment Coordinator, EPA Region 1
