Grease and Oil Interceptor Design and Sizing with Respect Dangers of Hydrogen Sulfide - 323

Interceptor design and sizing, combined with maintenance practices, can affect the build-up of Hydrogen Sulfide inside an interceptor. This toxic gas is hazardous to employees and can be converted by aerobic bacteria inside the interceptor to Sulfuric Acid, which is very corrosive in wastewater streams. This acidity generated can contribute to concrete and metal interceptor corrosion and downstream sewer and lift station corrosion. Excellent interceptor design and sizing is necessary to prevent these catastrophic effects.

Learning Objectives:

1. Upon completion, attendee will better understand pitfalls and best practices of interceptor design that can be immediately used at their job.
2. Upon completion, attendee will be able to properly size various interceptors and understand the pitfalls of incorrect sizing, with the impact to the customer. Knowledge can be immediately applied.
3. Upon completion, the attendee will understand the dangers of Hydrogen sulfide to employee health and how to overcome them through proper interceptor design and sizing.
4. Upon completion, the attendee will understand the long term dangers and ramifications of improper design, sizing and maintenance of interceptors, to then immediately focus clients to achieve optimal client solutions
