This is the Interceptor Whisperers Grease Interceptor Training Course. Attendees will receive an 85-page downloadable guide titled, Interceptor Whisperers Grease Interceptor Training Guide, a certificate of attendance, and 6 Contact Hours (subject to approval by CWEA). The course includes the following 6 modules:
Module 1: The History and Evolution of Grease Interceptors (50 minutes)
Attendees 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: Gravity Differential Separation – How All Grease Interceptors Work (50 minutes)
Attendees 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 emulsifications to understand the impact of emulsions and soaps or detergents on grease interceptor performance.
Module 3: How Grease Interceptors are Regulated in Model Plumbing Codes (50 minutes)
Attendees 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 (50 minutes)
Attendees 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 Properly Size and Select Grease Interceptors (50 minutes)
Attendees 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: Inspection and Maintenance Considerations for Grease Interceptors (50 minutes)
Attendees 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.
